January 2021 Weather Recap - Winter Makes Late Appearance

Late bloomer

 

If you're not a "winter person", then the first three weeks of January 2021 were tolerable, as temperatures were six degrees above average (with every day but two above average), and there was no snow (average high/low was 43°/33°).  Then, the jet stream shifted, and the last nine days of the month were five degrees colder than average (high/low of 33°/22°).  On the last day of the month conditions became even more wintry.  Up until the 31st, it appeared the month was going to be among the five least snowy Januarys on record, as just 0.1" had fallen.  But then, the opening volley of snow from a snowstorm that would bury the City on Feb. 1 dropped two inches between 6:00 and midnight - the most snow to fall on this date since 1898. 

 

Despite being 2.2 degrees above average, January's mildest reading was just 51° (on Jan. 2).  This was, by far, the mildest January to have its warmest reading this cool.  Previous Januarys with mildest readings that were either 50°, 51°, or 52°, had an average monthly temperature of 28.9°, which is is 5.9 degrees colder than January 2021 (34.8°). 

 

The coldest day of the month was the 29th, with a high/low of 25°/14° (thirteen degrees colder than average).  This was the coldest day in two years (since a high/low of 21°/11° on Feb. 1, 2019).  

 

With just 2.1" measured, this was the third consecutive January with snowfall that was well below average (January 2019, had 1.1", January 2020 had 2.3").  It was the fifth string of low-snow Januarys.

 

Chart - minimal snow consecutive januarys

 

With an average high of 39.7°, and an average low of 29.8°, January's diurnal variation was just 9.9 degrees, making this just the third January whose average high and low was less than ten degrees apart.  The two others were in 2017 and 1869 (variations of 9.4 and 9.8 degrees, respectively).  This narrow diurnal variation was largely due to the month's average low being notably more above average than the average high (+2.9 degrees vs. +1.4 degrees, respectively).

Analysis of Back-to-Back Days With the Same High & Low Temperatures

The same

 

In the years I've spent poring over New York's daily weather data, I'd notice pairs of days with the same high and low.  This analysis is the product of my curiosity about how common such pairings are.  On average, two occur each year (2.3 to be exact).  The most has been ten, which happened in 1931 and 2010.  There have been ten years with five or more pairs, including 2020.  Twelve years have had none.  (Of course, if temperatures were reported to one decimal place, these type of days would be even rarer than they already are.)  Here are some more interesting findings:

 

  • There have been three streaks that had three consecutive days with identical highs/lows - in 1988 (Aug. 3-5, all with a high/low of 89°/76°); 1984 (May 5-7, highs/lows of 69°/53°), and 1879 (May 8-10, 69°/49°).  And during the summer of 2013, after a high/low of 83°/67° on July 30-31, there was another day with the same high/low two days later, on Aug. 2.
  • There have been 23 pairs that missed by one degree of having a third consecutive day with the same high/low.  The most recent occurrence was in December 2010, when 12/7 had a high/low of 36°/30° after a high/low of 35°/30° on 12/5 and 12/6.  And each of the streaks of three-days (mentioned above) narrowly missed being four-day streaks:
    • Aug. 3-5, 1988's streak missed being a four-day streak when the high/low on Aug. 6  was 89°/75° instead of 89°/76°.
    • May 5-7, 1984's streak of 69°/53° was followed on May 8 by a high/low of 69°/55°.
    • The day before 1879's streak of May 8-10, with highs/lows of 69°/49°, the high/low was 70°/50°.
  • There have been three back-to-back pairs of days: July 28-31, 2010 (89°/74° on 7/28-29 and 85°/66° on 7/30-31); March 3-6, 1952 (pairs of 36°/32° and 42°/31°); and Aug. 17-20, 1906 (pairs of 85°/71° and 87°/77°).  And there has been one instance of three consecutive pairs of days: Dec. 16-21, 1901 (26°/20° on Dec. 16-17; 28°/20° on Dec. 18-19; and 26°/19° on Dec. 20-21).  (March 1952's and August 1906's streaks narrowly missed having three consecutive pairs.)
  • Of the 12 years with no pair of days, only one occurred after 1956 - 2000.  The other years: 1956, 1954, 1943, 1934, 1930 1924, 1916, 1903, 1889, 1881 and 1869.
  • There have been two instances of back-to-back years having the same pair of dates with the same high/low.  It first occurred on July 27-28, in 1897 and 1898.  (The pair of highs/lows in 1897 was 67°/64°, and 80°/74° in 1898.)  The second time was in 2020 and 2021 on May 29-30 (highs and lows of these pair were 81°/67° and 51°/47°, respectively).  And there have been five instances of pairs of the same dates being two years apart, most recently in 2018, when it and 2016 each had a pair of days on Dec 23-24.
  • July 27-28 has had the same high/low in six years, the most of any pair of dates: 2007, 1988, 1939, 1910, 1898, and 1897.
  • May 18-19, 1932 and May 18-19, 2005 had the same pairs of highs/lows (70°/53°).
  • There have been four pairs of 85°/70° highs/lows, which is the most frequent of any pair  (occurring on July 4-5, 2017; May 27-28, 2015; June 25-26 2014; and June 27-28, 1994).
  • July and August are the months most likely to have seen pairs of days with the same high/low (48 and 51 occurrences,respectively); February and October are the months least likely to report a pair of these days (with just 12 each). 
  • Hottest pair: 100°/79° on July 9-10, 1937; Coldest pair: 23°/14° on Jan. 28-29, 1986.

Review of 2020's Weather - New York's Second Warmest Year

Looking back

 

2020 was 2.4 degrees above average and became New York's second mildest year, behind 2012.  Only two months during the year, April and May, were chillier than average.  November became the mildest on record, July the seventh hottest, and February and March each became the eighth mildest.  January finished just outside the top 10, ranking eleventh, and June made it to sixteenth.  The summer was the fifth hottest (tied with 1983).  Despite 2020's warmer than average theme, there were some moments of chilliness worth noting:

 

  • April had no highs in the 70s or 80s for the first time in 80 years.
  • For the first time since 1978, May had readings in the 30s, and the low of 34° on the 8th was the coldest reading in May since 1891.
  • The year's last reading of 80° or warmer was on Sept. 10, which was the earliest of any year with 20 or more days with highs of 90°+.  A typical 90s/100s season lasts about three months (late May through late August), but in 2020 it was two months long (late June through late August).  However, the number of days in the 90s in 2020 was slightly more than average (20 days).
  • Later in September, the low of 49° on Sept. 21 was the the earliest for a low in the 40s since 1993.
  • Halloween had its first low of 32° or colder since 1988.

OTHER HIGHLIGHTS

  • The first half of the year was dry as the 16.15" measured was eight inches below average (the seventeenth driest first half on record).  The second half, however, had nearly twice as much precipitation, with 29.20" measured (three-and-a-half inches above average).  May and June both had less than two inches of rain, the first time since 1993 that these  months were this dry.  Overall, 2020 had 45.35" of precipitation, 4.59" below average.
  • Jan. 10 and 11 had record highs of 69° and 68°, respectively.  Meanwhile, chilly April's warmest reading was 68°, the first time since 1940 that April's mildest reading wasn't 70° or warmer.
  • The winter of 2020's last measurable snowfall was on Jan. 18, the earliest date on record for a last snowfall (breaking 2002's record by one day).  At the end of the year December's snowstorm produced more than twice as much as the previous winter.
  • Four tropical systems moved through the area.  The year's biggest rainmaker was from the first, tropical storm Fay, on July 10, which produced 2.54" of rain, most of it falling in a three-hour period during the afternoon.  While Fay brought the rain, tropical storm Isaias on Aug. 4 delivered ferocious winds, with 65-75 mph gusts common outside of Central Park (which had a peak gust of 48 mph).
  • July's coolest reading of 67° was the mildest coolest reading of any July.  Furthermore, July 2020 had the most lows in the 70s or warmer of any month (26).  This helped July become just the seventh to have an average temperature of 80° or above.
  • November had its first streak of six days with highs in the 70s (Nov. 6-11).  Later in the month, Thanksgiving Day's high of 65° tied for third warmest, and its low of 55° was mildest ever on this holiday.  The 0.79" of rain in the morning was the seventh greatest amount for Thanksgiving.
  • The 10.5" snowstorm of Dec. 16-17 was the biggest December snowfall in 10 years and the 13th during the month of 10 inches or more.  And at 1.7 degrees above average, December 2020 was the second mildest to have more than ten inches of snow.
  • An intense storm system on Christmas Day morning dumped the third greatest amount of precipitation on the holiday (0.92").  The day's high of 61° was the eighth reading in the 60s on the holiday.  The temperature dropped 32 degrees by midnight, which was the biggest daily drop in temperature all year.  2020 became just the second year (2015 is the other) to have highs in the 60s on Christmas Day (61°), Thanksgiving Day (65°) and Easter Sunday (63°).
  • Finally, the temperature profiles of 2020's first and last month were nearly identical.  However, December had more than twice the amount of precipitation than January and nearly five times as much snowfall.  Despite their similar temperatures January's was much more above average.

December 2020 Weather Recap: Two Storms Grab Headlines

Janice huff wnbc dec2020

 

The lasting memory of December 2020 will no doubt be the snowstorm of Dec. 16-17.  The 10.5" of snow that piled up was the biggest snowfall in December since 2010 and the thirteenth December snowfall of 10"+.  Another highlight was the intense rainstorm that blew through the City on Christmas morning.  The month was 1.7 degrees above average - the City's 34th mildest December (since 1869).  But despite being milder than average it had more days with highs of 32° or colder than all of last winter (four vs. three).  Additionally, the big snowstorm produced more than twice as much snow as the previous winter (10.5" vs. 4.8").

 

  • Five days had highs of 55° or milder while six days had lows of 25° or colder.  There were three days with highs in the low 60s, evenly spaced, on 12/1 (62°), 12/13 (62°) and 12/25 (61°).  Five of the six days with lows of 25° or colder had lows of 24° (the outlier was the reading of 20° on 12/19).
  • The mildest and coldest periods of December occurred during the fifteen-day period from Dec. 11 thru Dec. 25.

 

Chart - december 2020 coldest_mildest periods

 

  • Christmas Day's high of 61° (before sunrise) made it the eighth Christmas with a high in the 60s, and the 0.92" of rain that fell was the third greatest amount on the holiday.  After the high was reached the temperature fell steadily throughout the day and was down to 29° by midnight.  This 32-degree drop was the greatest of any calendar date in 2020.
  • Although the month was on the mild side, five Decembers in the past ten years were even milder.

 

Chart - mildest decembers since 2011

 

  • December 2020 was the 29th December with ten or more inches of snow (nearly 20% of all Decembers).  However, it was the second mildest December (after Dec. 1912) to have this much snow.  Although their average temperatures weren't quite as mild as this December, the Decembers of 1948, 1959 and 2003 had considerably more snow (25.3", 15.8" and 19.8", respectively).

 

Chart - snowy mild decembers

 

  • Much of the month's 4.61" of precipitation (0.61" above average) fell from three storm systems, all which produced more than an inch of precipitation:  1.13" on Dec. 4-5; 1.52" on Dec. 16-17; and 1.16" on Dec. 24-25.
  • Finally, similar to November, December had a lot of days with gusty winds, with Central Park having nine days with a peak gust of 33 mph or more.  The peak gust of 47 mph occurred early Christmas morning.

Dry Months in New York

Drier than normal

 

For the purposes of this analysis a dry month is one that had less than two inches of precipitation.  In the years since 1869, 18% of all months have been this dry, or about two months each year.  The most dry months in one year is six, which happened in 1910, 1946 and 1965.  The most consecutive months with less than two inches measured is four, which occurred in 1881 from July thru October.  Finally, there have been 15 years in which no month had less than two inches - most recently in 2018 (two of these 15 years were consecutive, in 2010 and 2011).

 

Graph - precip of less than 2 inches by month

 

CONSECUTIVE DRY MONTHS WITHIN A YEAR

The most consecutive months with less than two inches of precipitation is four, which happened in 1881 between July-October (1.25", 0.86", 0.97" and 1.60").  There have been nine other years that had three dry months in a row, the most recent being in 1993.  The smallest amount of rain during one of these streaks was 2.98" in 1910 (July-Sept.).

 

Chart - 3 months in a row with less than 2 inches

 

Two of the three years that have had six months with less than two inches of precipitation, 1910 and 1965, are among New York's ten driest years, but the third, 1946, is ranked 27th.

Five Octobers in a row from 1946-1950 had less than two inches of rain.  And there have been three other months that had this little precipitation in four consecutive years: January 1954-57; May 1902-05 and September 1884-87.  And seven of the nine Novembers between 1901-09 had two inches or less.

 

LESS THAN ONE INCH OF RAIN

Nearly one out of four dry months had less than one inch of rain, or about once every two years.  The greatest number of these very dry months in one year is three and it's happened twice, in 1881 and 1955.  The most years in a row to have the same month report less than one inch is two, which has happened three times: July 1954 (0.96") & 1955 (0.51"); Sept. 1884 (0.21") & 1885 (0.41"); and Oct. 2000 (0.68") & 2001 (0.66").

 

DRIEST MONTH OF EACH YEAR

On average, the driest month of a year has had 1.24" of precipitation (and most likely to happen in October).  About 40% of all years have had less than an inch of precipitation during their driest month.  June 1949 is the driest month of all time, with just 0.02" measured; the driest month in recent years is October 2013, which had just 0.36". The most consecutive years with a driest month reporting less than an inch is four, which was between 1999-2002.  

Thirteen years have had more than two inches as their driest month.  And two of them had more than three inches: 3.04" in 1975 and 3.03" in 2011. 

In both 1980 and 1981 the driest month had 0.58" of precipitation, and it was in consecutive months - Dec. 1980 and Jan. 1981.  And later in 1981, August had 0.59".  Two other years' second-driest month also had just 0.01" more than the driest month (1900 and 1975), while 1926's second driest month had 0.02" more.  And in 2000, 2001 and 2002 the driest months had 0.68", 066" and 0.71", respectively.

In the three consecutive years between 1903-1905, May was the driest month, and in the three consecutive years 1945-1947, October was the driest month.  Finally, in the four-year period 1967-1970 three of the years had January as their driest month (1967, 1968 and 1970).

Notable December Cold Snaps

The weather outside is frightful

Nearly 40% of Decembers since 1869, or 59, have experienced cold snaps/cold waves that lasted five days or longer (about half were seven+ days).  The most recent occurred in 2017.  In addition to the five-days+ qualifier, a cold snap needed to have an average high temperature of 32° or colder to be part of this analysis.  The longest of them lasted 15 days, in 1876; six have had sub-zero readings; six had twelve inches of of snow or more; and six had no snow whatsoever (not even a trace).  Finally, six Decembers had two periods of Arctic cold.

 

COLDEST

The coldest December cold wave occurred in 1917, when the six days between Dec. 17-22 had an average high/low of 17°/2°.  Most recently, the last six days of Dec. 2017 had an average high/low of 23°/15°, which tied for ninth coldest.

 

Chart - coldest december cold snaps

LENGTHIEST

Fifteen Decembers have had cold waves lasting ten or more days.  The lengthiest was 16 days in Dec. 1904 (average high of 32°/22°), followed by a 15-day stretch in 1876 (27°/17°).  The coldest of these lengthy cold waves was one of 10 days in 1872 (24°/10°).

 

Chart - lengthiest december cold waves

 

TWO IN ONE MONTH!

Six Decembers had two significant cold snaps.  The last time it happened was in 1955, with one of five days and the other lasting six days (they were three days apart).  The two in 1917 covered 15 days (eight days apart).

 

Chart - decembers with two cold snaps

 

COLD SNAPS MORE PREVALENT 100+ YEARS AGO

The greatest concentration of Decembers with cold waves was between 1876 and 1904, when 20 of the 29 Decembers had at least one cold snap.  The most consecutive Decembers to have a cold snap is four, which has happened four times: in 1901-1904, 1914-1917, 1932-35 and 1942-45; there have also been four three-year streaks, with the most recent being 1958-1960.  The most consecutive years without a cold snap is eight, and it's happened twice, in 1981-1988 and 2001-2008.  And there was a seven-year hiatus from 2010 to 2016.

 

SNOWIEST & LEAST SNOWY

Six cold snaps received more than 13 inches of snow.  The most was 22.5" in 1883 and 21.5" in 1872.  The most recent was in 2000 when 13.3" fell.  Five of the Decembers had snowstorms that dumped a foot or more, with the most being 18.0" on Dec. 26, 1872.  And although December 1942, with 6.0", isn't found on the "most snowy" list below, it's worth mentioning because it had measurable snow on six of the cold wave's ten days.

 

Chart - snowiest december cold snaps

 

At the other end of the snow spectrum, ten December cold snaps had no measurable snow.  Eight of them were five or six days in duration, but December 1870 and December 1989 lasted 11 and 10 days, respectively.

 Chart - december cold snaps with no snow

BELOW ZERO READINGS

Seven of the Decembers had at least one sub-zero low.  The most recent was in 1980 (on Christmas Day).  These cold waves accounted for all of the twelve sub-zero lows that have been reported in December.  And although December 1872 had no below-zero readings, it had the distinction of having six days in a row with lows in the single digits (ranging from 4° to 8°).  At the other end of the spectrum, the coldest temperatures of five December cold snaps was a relatively mild 18° or 19° (most recently in 1970).

The Coldest Day of New York Winters

Frozen bryant park fountain

 

Since 1900 the average high/low on the coldest day of each winter has been 19°/6° (in the last third of the 18th century it was 14°/2°; in the 21st century it's risen to a relatively temperate 20°/9°).  The coldest day has occurred as early as Nov. 30 (winter of 1875-76) and as late as March 15 (winter of 1931-32).  Nearly half of the coldest days of New York's winters have occurred in the four-week period between Jan. 9 and Feb. 6.  For this analysis "coldest day" is based on daily mean temperature (average of high/low), not just the low temperature.

 

Chart - warming of coldest winter day

 

THE SPECTRUM OF THE BIG CHILL

The dates of the most frigid coldest winter day and the mildest coldest winter day are, in their respective years, one day apart.  The coldest of them all fell on Dec. 30, 1917, when the high/low was 2°/-13°.  At the other end of the spectrum, the mildest reading to have the distinction of being the coldest day of a winter was 31°/20° in the winter of 2001-02 on Dec. 31, 2001January 18 is the date to see the most coldest days of winter - six.  Three dates in February have been the coldest for five winters each: Feb. 2, Feb. 5 and Feb. 17.

 

Chart - coldest day jan 18
 

TWO MEASURES OF "COLDEST"

Although the coldest day is usually the same date as the coldest temperature, they have occasionally occurred on different dates (on average, in one out of four winters).  For instance, although the coldest reading of all time is -15°, the coldest day of all time, based on mean temperature, had a low of -13°.  Although this is two degrees "warmer" than the coldest reading, the day's high of 2° was six degrees colder than the high on Feb. 9, 1934, so it ended up with a mean of -5.5° compared to a -3.5° in 1934.  (The most recent instance was the winter of 2019-20 as its coldest day was on Dec. 19, with a high/low of 25°/16°, while the coldest reading was 14° on 2/15.)

 

SIMILAR DATES

A number of consecutive years, or a few years apart, have had their coldest day on practically the same date.  And in one interesting case the coldest day of winters one hundred years apart (1916 and 2016) occurred on the same date - Feb. 15.  And the coldest day of the winters of 1884 and 1984 were two days apart, on 12/23 and 12/25, respectively.

"COLDEST COLDEST, MEET MILDEST COLDEST!"

Of course, the coldest winters have a lot of very cold days that that would easily qualify as the coldest dates of many of the winters with average or above average temperatures.

SOMETIMES IT SNOWS

Snow falls very infrequently on the coldest day of the winter - just six winters have had an inch or more of snow on this day.  However, a few were significant, with the stand out being the 12.5" accumulation on the coldest day of the winter of 1966-67 (Feb. 9, which had a high/low of 16°/7°).

 

Chart - snowy coldest days of winter

Finally, the coldest day of the winter of 1963-64 was preceded by a snowstorm that dumped 11.5" the day before, while three storms that followed the coldest day of winter by one day dumped more than ten inches.  The storm in February in 2003 dumped 16.3", but started on the coldest day of the winter, with 3.5" falling that evening.

November 2020 Reigns As Mildest November On Record

WashSqPk_Nov2020

 

November 2020 was 5.2 degrees warmer than average and became the warmest November on record, supplanting November 2015 by 0.2 degrees.  Sixteen days had highs in the 60s or 70s (one fewer than the 1931 record).  What stood out was a streak of six days with highs in the 70s from Nov. 6-11, the longest such streak to occur in November.  (And the seven days between Nov. 4-10 all had clear or mostly sunny skies.) Conditions on Thanksgiving Day were noteworthy as well.  Although the high of 65° wasn't the warmest on record (it tied for third warmest), its low of 55° was.  (Just two years ago Thanksgiving Day had a high/low of 28°/17°.)  It was also one the seventh rainiest Thanksgiving, with 0.79" falling in the morning.  What follows are a few other observations:

 

  • Typically, November is 5.4 degrees cooler than April.  This year, however, it was 2.4 degrees milder and became just the tenth November to be milder than April.  (Nov. 1975 was warmer than April by the greatest margin, +4.4 degrees.)
  • The eight-day period between Nov. 5-12 was 14 degrees above average.  The rest of the month was two degrees above average.  These 22 days included four days that were ten or more degrees above average and two other days that were ten or more below average.  Overall the month had nineteen days that were five or more degrees above average.
  • At 3.99", the month's rainfall was an average amount, and that was thanks to a rainstorm that brought 0.98" on the last day of the month.  It was also the month's biggest rainstorm.  This storm was accompanied by gusty winds.  The peak gust was 35 mph, which was the seventh day of the month to report a peak gust of 30 mph or greater (the area's three major airports, LGA, JFK and EWR had gusts of 30 mph+ on ten, twelve and nine days, respectively, and their peak gusts were much higher).

  • Despite being the warmest November on record, this November is tied with Nov. 2011 for warmest average high and tied for fourth mildest average low.  Additionally, Nov. 2020 had two days with sub-freezing low temperatures (both were 30°) while half of the ten mildest Novembers had coldest readings that were above freezing.
  • Besides this November, Nov. 1994 and Nov. 1975 also had six days in the 70s (but they weren't consecutive).  But they rank second behind Nov. 1953, which had seven such days.

Weather Highlights of the Late 19th Century (1869-1899)

 

New york late 19th century

 

Central Park's first three decades of weather records, from the latter part of the 19th century, reveal that New York was significantly colder than what we've been accustomed to in the past 40 years.  These decades account for twelve of New York City's fifteen coldest years - and all of the ten coldest springs and nine of the ten coldest falls.  On average, the typical temperature of months back then was three to four degrees chillier than they are now, with March and April showing the biggest differences (6.1° and 5.4° colder, respectively).  Of course, this is not to say there weren't interludes of unseasonable warmth that wouldn't have been out of place in the 2000s.  What follows are year-by-year highlights.

 

 

- 1869 -

January 1 - The year had a snowy start with nine inches piling up - a record for the date that, amazingly, still stands.

February 15 - The City's longest-standing daily precipitation record was set today in 1869 when 2.60" of rain fell.  (This amount contributed to February 1869 being the wettest on record - and 151 years later it still is.)

February 26 - A snowfall of six inches was the third snowfall of six inches or more in Jan./Feb., joining another six inch snowfall on Jan. 19 and the nine inch snowfall on New Year's Day.  Today's snow was of the wet variety as it fell in temperatures that hovered around the freezing mark.

October 2-3 - Four inches of rain came from a hurricane that struck Cape Cod (1.84" fell on the 2nd, 2.16" on the 3rd).

 

- 1870 -

February 8 - A snowfall of eight inches was the only measurable snow in February until the last day of the month (when 1.1" fell).  This was also the biggest snow of the winter.

March 17 - This was the sixteenth day in a row with a low in the teens or 20s.  The average was 25°, with readings ranging from 19° (today) and 29°.

 

Clipart_winterblues

 

July 25 - 11 of the past 15 days had highs of 88° or hotter, including seven days in the low 90s (during heat waves of three and four days).  Additionally, every day had a low of 70° or warmer, and six had lows of 77°+ (one of which was 82°). 

September 30 - After going five weeks with less than an inch of rain, 1.63" fell today.  This was the biggest daily rainfall of the year until 10/12 (when 1.91" fell).

 

- 1871 -

February 5 - For the second day this winter the high was a frigid 11°.  The other occurrence was on 1/23.  Lows on these days were 2° and 0°, respectively.

11 degrees
 
March 21 - This was the fifteenth day of the past nineteen to have measurable precipitation, and today's amounted to 1.97", making this the rainiest of them all.  In total, 4.76" was reported (0.1" was snow).

March 27 - For the fourth day in a row the low temperature was 33°.

April 8 - Today's high of 85°, the warmest reading of the month, came just two days after a low of 33°, which was the chilliest reading of the month (tied with 4/2).  It would be another seven weeks before the next reading of 85° or warmer occurred.

July 16 - This was the eighth day in a row with a high of 85° or warmer (just one of the days was in the 90s) and the twelfth day in a row with a high of 84°+.

August 30 - This was the eighth day in a row with measurable rain, which totaled 3.85".  Two of the days (8/25, 8/26) had about an inch.

 

Umbrella 19th century
 

September 30 - Today's high was 61°, making it the eighth day since 9/14 with a high in the 56°-62° range; average high during this time of September is in the 70°-73° range.  These unseasonably cool days helped September 1871 become the coolest September on record (a mark that still stands).

October 10-11 - Just four days after the biggest rainstorm of the year (2.72" on 10/6) a low pressure system brought nearly the same amount (2.65", of which 2.44" fell on the 10th).

December 1 - This was the fourth day in a row with highs in the 20s and lows in the mid-teens.  The average high/low of these four days was 25°/16°, twenty degrees below average.  This would be the longest such streak this winter.

December 21 - The first day of winter had the coldest reading of the entire winter, two degrees below zero.  (Two days later the temperature jumped to 55°.)

 

- 1872 -

March 5 - This morning's low was 3°, the coldest reading ever experienced in March.  This was the second coldest reading of the winter (coldest was -2° on 12/21).

July 5 - This was the sixth day in a row with highs in the 90s, and was the City's longest heat wave until one of ten days broiled New York in the summer of 1896.

October 26 - The center of circulation from a dissipating hurricane got very close to Manhattan as it moved northeastward, dropping 1.56" of rain.

November 6-11 - High temperatures during this six-day period exhibited to following pattern: 55°-55°-50°-50°-55°-55°.  These readings were at seasonable levels.

December 26 - On a day with frigid temperatures (the high/low was just 12°/6°) New York City experienced its first of four crippling snowstorms on 12/26 (the others would be in 1933, 1947 and 2010).  Eighteen inches piled up, making this New York's biggest snowstorm until the Great Blizzard of March 1888.  (It's now ranked twelfth.)

December 27 - The morning low of 6° was the sixth day in a row with a low in the single digits.  There would be eight more days with lows of ten degrees or colder this winter, which ranks as New York's seventh coldest winter on record.

 

- 1873 -

February 24 - Today, with a low of -1°, became the latest date for a sub-zero low - a record that remains intact. This sub-zero low came about four weeks after another reading of -1° on Jan. 30.

 

Minus 1

February 27 - A snowfall of four inches was the fifth this month of two inches or more.  (The month's snowfall amounted to 18.9".)

March 10 - The 0.3" of snow that fell today was the last measurable snow of what was New York's snowiest winter for the next 50 years, with 60.3" measured.  (The winter of 1923 would top it by 0.1").  It's now ranked fifth.

 

- 1874 -

January 7 - The 3.14" of rain that fell today was the greatest daily rainfall in January for more than 100 years (until 1979).  It was also a mild day, with a high of 56°.

April 30 - The last three days of the month had lows of 32° or colder, joining eight other days with lows this cold.  No other April has had this many days with lows of freezing or colder, which contributed to this being the coldest April of all time.  (The following April, and April 1943, would have nine such days, the second most.)

September 29 - What was once the season's sixth hurricane moved over New York as a tropical storm and dropped 0.64" of rain on Central Park.  This was considerably less than the seven inches of rain that flooded the City from Sept. 16-18 from a non-tropical system.

December 20 - Ten inches of heavy snow piled up after starting out as rain.  As the temperature dropped below freezing (from a high of 36°) it changed over to snow.  Total liquid precipitation for the day was 1.92".  (Both amounts are records for the date that are still standing.)

 

- 1875 -

January 4 - Today's high of 40° was the mildest reading of the month, making it the chilliest mildest reading of any winter month.  (January 1875 would be the coldest January until 1888, and has since fallen to seventh coldest.)

February 23 - Today had the first low above 32° this year - the deepest into the year for this occurrence (a mark that still stands).  The reading of 42° was the mildest since Nov. 17th's low of 43°.

March 20 - An ice storm on the first day of spring dropped 0.54" of liquid precipitation in temperatures that were below freezing all day (high/low was 31°/22°).

March 23 - Five of the past six days had highs of 32° or colder.  Average high/low during these six days was 31°/18°, seventeen degrees colder than average.

April 13 - A heavy snowfall totaling ten inches began today and ended in the wee hours of the morning of the 14th.  However, the snow didn't stick around for very long as tomorrow's temperature rose into the low 50s after dark.

April 17-18 - An Arctic high delivered mid-winter cold, with highs/lows of 33°/27° and 32°/25°.  These highs were 25 degrees below average. 

April 22 - This was the sixth day in a row with a low in the 20s (average low this time of the month is in the low-to-mid-40s).  This helped this month become the second coldest April on record (behind April of last year).

 

20s

April 25 - Less than two weeks after a snowstorm of ten inches, another significant snowfall dropped three more inches - despite the fact that the temperature got no lower than 34°.  This is Central Park's latest measurable snowfall on record.

August 8 - This was the fifth day in a row with very similar highs/lows: 82°/68° (8/4)-82°/69°-82°/67°-82°/70°-81°/71° (8/8).

October 24 - This was the third day in a row with a high of 71° and it came a month after another three-day streak of 71° highs (Sept. 27-29).

November 5 - The first five days of the month were twelve degrees colder than average, with an average high/low of 42°/33°.

November 30 - It was a bitterly cold day with a high/low of just 14°/5° (31 degrees below average).  This was the earliest date for a reading in the single digits and a high in the teens.  It was also colder than any day of the winter to come (based on mean temperature).

 

- 1876 -

February 4 - Eleven inches of snow fell from a storm that began last night and continued into today, when most of the accumulation occurred.  This was by far the biggest snowfall of the winter as only 7.3" fell from eight other snowfalls.

September 17 - Heavy rain from a minimal hurricane that raced inland through North Carolina and Virginia dumped 3.37" of rain in Central Park (a record for the date that still stands).

October 15 - 0.5" of snow accumulated, the earliest measurable snowfall on record (a record that still stands).  The day's low of 32° was also a record.

Nov. 30-Dec. 2 - For the second year in a row (on the very same dates) the City was in the grips of an early incursion of Arctic air.  This year, however, temperatures were a bit "milder" (average high/low of 27°/18° vs. 23°/10°).

 

- 1877 -

January 1-2 - The year started with a snowstorm that dumped 13.0" on the City (4.8" on New Year's Day, 8.2" on the 2nd).  This amount was more than the five snowfalls in December that totaled slightly more than twelve inches.  Both days of the snowstorm had highs of 24°.

March 10 - The day after the mildest reading of the month (57°), the temperature at daybreak was 21°.  This was the first of eleven days in a row in which there were no highs milder than 40°; four days in a row would see lows in the teens (coldest reading was 10° on 3/19).  The average high/low during this very cold outbreak was 32°/22° (eleven degrees colder than average).

March 19 - Yesterday's and today's frigid highs and lows of 26°/12° and 22°/10° were comparable to the Arctic cold experienced on the same two dates the previous year (30°/9° and 27°/9°). 

April 21 - Lows of the past six days exhibited the following pattern: 40°-42°-41° and 40°-42°-41°.

October 4 - A dissipating tropical storm dumped 4.05" of rain in Central Park (a record for the date that still stands).

 

- 1878 -

January 18 - This was the third day in a row with a high of 32°.

February 1 - Today's two-inch snowfall was the last measurable snow of the winter (sleet was also part of the mix).  This would be the earliest date for a winter's last snowfall until 2002, when the last snowfall happened on 1/19 (and it occurred on 1/18 during the winter of 2020).  In total 8.1" of snow fell during the winter of 1878. 

March 25 - A mild March was interrupted by one day of mid-winter temperatures as the high/low was only 30°/13° (twenty degrees below average); the previous day with a high of freezing or colder was five weeks ago.  The low was a record for the date (which still stands).  

April 18 - Today was the sixth day this month with a low of 42°, which was the chilliest reading of the month.  This is the mildest reading to have the designation as the chilliest temperature of any April.  (In the years between 1869-1899 the coldest reading in April was typically in the upper 20s).

October 23 - The center of the dissipating "Gale of 1878" moved west of Manhattan.  Shortly after daybreak winds gusted over 50 mph and 0.73" of rain was measured in Central Park.

- 1879 -

January 16 - A snowstorm during the morning and afternoon produced an accumulation of thirteen inches.  Temperatures were quite cold, with a high/low of 20°/13°.

May 10 - This was the third day in a row with a high/low of 69°/49°.  This was the first time for this type of streak, and has since been replicated just two other times (in May 1984 and August 1988).

August 18 - 3.95" of rain flooded the City from bands of heavy rain produced by a hurricane that struck North Carolina this morning and moved up the coast during the day.  This amount was a record for the date (a record that still stands).

October 18 - Today's low of 63° was the thirteenth low in the 60s or milder this month, the most such days on record for October (October 2007 and 2017 would have 12). 

November 5 - 1.5" of snow fell on a day with a low of 23° - both are records that still stand.  This was also the third day in a row with a high only in the 30s (typical high in early November is in the mid-50s).

 

- 1880 -

April 14 - Today's high of 80° came just two days after a record low of 26° (since eclipsed in 1976).  This was the first reading above 64° since 3/5 (when it was 72°).

September 9-10 - Rain from a hurricane moving north from South Carolina started late on the 9th (0.67" of rain fell) and continued into the morning of the 10th (adding 0.54"). 

November 28 - This was the eighth day in a row with a high of 32° or colder.  The average high during the unseasonably cold streak was 29°/18°.  (Average high temperatures during this time in November are in the upper 40s.)

December 1 - The 1.5" of snow that fell today is the only time an inch or more of snow fell on this date.

December 4 - This was the fourth day in a row with a high of 38° (but each day's low temperature was different). 

 

- 1881 -

February 11 - Today's high of 52° was the first in the 50s in three months (since Nov. 12).

April 6 - During the past eight days the mildest high temperature was just 41°.  And the last two days of this streak had highs below 32° (more than twenty degrees below average).

September 7 - Today's high of 101° was the first time on record that a high in the triple digits occurred in September.  More than one hundred years later it continues to be the latest date with a high of 100°+.  (There has been only one other date with a high in the 100s in September - Sept. 2, 1953).

 

101 degrees

 

October 1 - Today's summer-like high/low of 87°/72° featured the first low in the 70s in the  month of October.  (It would be another 17 years until the next low this mild happened in October; in total, nine years have had lows in the 70s in October, with the last time being in 2018.)

 

- 1882 -

February 4 - A snowfall of nine inches followed a snowfall of eight inches on Jan. 31.  (Eight of the inches fell today.)  Temperatures were quite cold, with a high/low of 22°/13°. 

April 4 - Today had the first 80°+ reading of the year, which followed the first reading in the 70s yesterday (75°) and first reading in the 60s the day before that (61°).

 

Central park 1890s
 

September 11 - Rain from a tropical storm amounted to 3.23", with much of it (2.57") falling today.

September 23 - Less than two weeks after heavy rains from a tropical storm soaked the City another tropical system brought more flooding rains to the Mid-Atlantic states and drenched New York with its greatest rainfall for any calendar date - 8.28".  And in the preceding two days 3.52" of rain fell.  With a total of 16.85" of rain for the entirety of September (most of which fell between the 11th and 23rd), this would be the wettest month on record until August 2011 (when 18.95" was measured).

November 18 - Today's high was 63° and would be the last day of 60° or milder for four-and-a-half months, until 4/1 next year (when the high reached 70°).

November 29 - A snowfall of nine inches followed by four days a 4.5" snowfall.  And with a high/low of 27°/23°, today was the fourth in a row with a high of 32° or colder. 

December 31 - After 14 inches of snow fell in November (the second snowiest November), December had no snow at all, not even a trace (just one of six Decembers to have this distinction).  This was despite the fact that it was a cold December (17th coldest on record), with 23 days with highs below 40° and 24 days with lows of 32° or colder.  

 

- 1883 -

February 10-11 - Eight inches of snow piled up, the second biggest snowfall of the winter (one inch less than the snowstorm of Nov. 29).  However, today's snow changed to rain as the mercury rose to 36° while November's snowstorm had much colder air in place (the high was just 27°).

February 24 - High temperatures today and the previous four days: 34° (2/24)-35°-36°-37°-38°(2/20).  These were below the seasonable average of 40°.

March 12 - This was the tenth day in a row with highs colder than 40°.  (This followed the mildest reading of the month, 60°).  High/low during this time was 33°/17°, ten degrees below average.  Two snowfalls during this streak amounted to 5.5".

March 30 - A snowfall of 4.5" was the sixth snowfall of four inches or more this winter (this was despite the fact that no measurable snow fell in December).

April 24 - 0.5" of snow accumulated, the second latest date on record following 4/25 in 1875 (when three inches fell).  Despite the snow the temperature got no lower than 34° (similar to 4/25/75). 

September 4 - The earliest date for a reading in the 40s occurred today when the low fell to 47°.  The average date for this occurrence is a few days after the first day of autumn.  The high was also on the cool side, 68°, which was one degree higher than yesterday.  (Sept. 1883 is the third coolest September on record.) 

December 17-25 - Five snowfalls during this nine-day period produced 22.6" of snow, the second greatest amount of any December (now ranked third).  A little more than half fell on 12/24 and Christmas Day, when 12.3" piled up from two different snowfalls.  This nine-day period had an average high/low of 28°/17°.

December 23 - It was a frigid, frigid day with a high/low of just 10°/-1°.

 

ArcticAir

 

- 1884 -

February 29 - The day after an Arctic front changed rain to snow that accumulated five inches, today's high/low was just 12°/4° (twenty-seven degrees below average).  This was the second coldest day of the winter after 12/23 and its high/low of 10°/-1°.  The next five days (March 1-5) would have moderating temperatures but all had highs below freezing (the average high of these five days was 23°/12°).

March 30 - It was a very late date for a sub-freezing high temperature (31°) at a time of the month when the average high is around 50°.

May 30 - It was a chilly Memorial Day, with a record low of 42° (a record that still stands).  And the day's high of 55° was also a record for chilliest high for the date.

June 26 - Almost all of June's 4.98" of rain poured down from a rainstorm that began yesterday evening and continued today.  In total, 4.74" of rain was measured, with 4.29" of it falling today.  Today was also unseasonably cool, with a high/low of 67°/58°.

September 11 - This was the eighth unseasonably warm day in a row, with afternoon highs that ranged from 88° to 91° and lows that were between 71° and 77°.  The average high/low during this period, 89°/75°, was 14 degrees above average.

September 30 - The last three days of the month accounted for all of September's rain, and it was very little - 0.21", making this the driest September on record (a dubious honor that it still holds).

October 22 - Today's 0.89" rainfall was comparable to the amount that fell in the previous seven-and-a-half weeks (since 8/31), a period that would typically receive about 6.50".

November 23 - Today's high of 61° tied 11/5 and 11/6 as mildest reading of the month, which was on the cool side for the distinction.  And yet it would be nineteen weeks before a milder reading was reported (66° on 4/3).

December 20 - The day before the winter solstice began was the coldest day of the winter as the high/low was only 7°/-3°.  Feb. 11 (1885) would come close with a high/low of 11°/-2°. 

 

- 1885 -

February 11 - Although it was brutally cold, with a high/low of only 11°/-2°, there was an even more frigid day earlier in the winter - on 12/20, which had a high/low of just 7°/-3°.

March 18 - Today's low of 8° was the 18th in the single digits or colder this winter, breaking a tie with the winter of 1872-73 for most on record (later passed by the winter of 1918, which had 20 frigid lows).

March 24 - This was the eighth day in a row with lows in the teens or colder.  The average low during this stretch was just 13°, twenty degrees below average.  (March 1885 is the third coldest on record).

May 31 - Today's rainfall of 0.11" brought this spring's total rainfall to 4.95", making it the driest meteorological spring on record (a record that still stands).  And the month of June would continue these dry conditions, with just 1.32" measured. 

July 21 - Today's high was 99° and came in the midst of a sweltering eleven-day period between 7/16 and 7/26 in which eight days were in the 90s.

October 13 - A tropical storm moved northward through central Pennsylvania and dropped 1.50" of rain in Central Park. 

 

- 1886 -

January 15 - This was the tenth day in a row with sub-freezing highs (including five days in a row with lows in the single digits).  The average high was 22°, ranging between 8° and 31°.   There was one snowfall during this cold stretch - five inches on Jan. 9.

February 8 - This was the 34th day in a row with highs colder than 40°.  Twenty-one of these days had highs of 32° or colder.  Nearly 19" of snow fell from six snowfalls.

 

Winter during victorian era

 

June 23 - A tropical storm passing to the south of New York, dropped 1.20" of rain.  Cloud cover and rain kept the temperature in the 60s all day (the high/low was 66°/62°).

 

- 1887 -

March 21 - Today's high of 49° was the mildest reading this March - the only March with its mildest reading below 50° (it would happen a week later as well).  By comparison, January and February each had a reading in the low 60s.

March 29 - The temperature fell slowly throughout the day, from 29° shortly after midnight to 19° nearly 24 hours later.

April 18 - Rain changed to snow, accumulating 3.0".  This followed a two-inch snowfall on April 1-2.  Today's snow was a week earlier than the latest measurable snowfall on record, in 1875, where there was a three-inch snowfall on 4/25.

June 1 - After experiencing what, at the time, was the driest May on record (0.34" was measured; it's now ranked second after May 1903), June began with a rainfall of 2.60", which was more than what fell in the previous six weeks.  It was also a record for the date (which still stands).

July 31 - The final week of the month had high temperatures that ranged between 88° and 91°.  In total. the month had 17 days of 88°+.  And there were 18 days with lows of 72° or warmer.  At the time this was the third hottest July on record, and it would be among the five hottest until 1949 (it's now ranked 28th).

September 25 - This morning's low of 40° was the second earliest date for a reading this chilly in September (earliest date was on 9/21 in 1871; 1887 has since fallen to third earliest).

- 1888 -

March 12 - The Blizzard of '88 (also known as the Great White Hurricane) roared into an unsuspecting New York during the morning and brought the City to a standstill for the next few days.  16.5" of snow fell today, with an additional 4.5" falling tomorrow into the early morning hours of the 14th.  This was New York's biggest snowstorm until Dec. 1947 (it's now ranked fourth).  In addition to the large amount of snow, the storm's danger was magnified by mountainous snow drifts created by winds that gusted between 45 and 55 mph, and extreme cold, as the temperature dropped from 33° to 8°.  200 people died in the City, many from exposure to the elements. 

March 13 - A bit more snow (three inches) fell today from yesterday's blizzard, but what stood out today was the extreme cold (even by mid-winter standards) as the high/low was just 12°/6° - the second coldest day ever experienced in March (the high/low on March 5, 1872 was 10°/3°).  With gusty winds still prevalent, wind chills were below zero.  This was the fourth March in the 1872-1888 period to have two days with lows in the single digits; since then it's happened in just one other year (in 1916).

 

Blizzard of 1888
 

August 21 - The remnants of a hurricane that first struck south Florida, then Louisiana a day later soaked the City with 4.12" of rain (a record for the date that still stands) as it traveled just to the north of the City on its way to New England.

September 8-21 - In a two-week period (including a six days in a row, between Sept. 8-13) measurable rain fell on eleven of the days, amounting to nearly seven inches.  Three days (today was one of them) had more than an inch, another three had between 0.50"-0.99".

October 5- Today's high of 66° was the warmest reading this month - the only October to have its warmest reading cooler than 70°.  (Three Octobers' warmest readings have been 70°, most recently in 1977.)

 

- 1889 -

January 10 - Although every one of the first 10 days of January had lows in the 30s, none were 32° or colder.  The average of 36° was twelve degrees above average.

May 10 - The first reading in the 90s this year (91°) was very early but after today there would be just one more (on June 9).

August 1 - The wettest July on record (11.89" was measured) continued into the first day of August, which was the third day in a row to have more than an inch of rain.  In total 5.68" fell during these three days (1.70" fell today).

August 14 - Since July 15 nearly fourteen inches of rain fell.  Six days had an inch or more.

September 10-13 - A dissipating hurricane stalled off the Delmarva Peninsula and brought bands of rain over the course of four days, amounting to 4.46", with much of it (3.34") falling on the 12th and 13th.  Except for one hour during the afternoon of the 13th the temperature was stuck in the 60s.  These four days were the start of streak of nine days in a row with rain (and ten out of eleven); total rainfall during this period was around six inches.

 

Rainy evening 1890s

September 18 - This was the ninth day in a row with measurable rain.  In total 5.93" fell, with more than half (3.34") falling on the 12th and 13th.

December 19 - This was the last day of precipitation this year, bringing 1889's total to 57.19".  At the time this was rainiest year on record, and it would hold the crown until 1903 (it's now ranked 14th.) 

 

- 1890 -

March 19 - A late season snowfall of six inches was the largest accumulation of the winter, beating the snowfall of Dec. 14 by half an inch.

September 4 - Today's high of 88° made this the warmest reading in September.  This was the sixth year in a row in which there were no 90-degree readings in September, the longest such streak on record.

December 26 - Seven inches of snow fell today.  A month later (1/25) it would be edged out as the biggest snowfall of the winter when eight inches piled up.

 

- 1891 -

January 25 - After precipitation started as cold rain, it changed to heavy snow which accumulated eight inches.  This was the biggest snowfall of the winter, overtaking a seven-inch snowfall on 12/26.

March 2 - The morning low of 9° was the coldest reading all winter.  This was similar to last year when the only reading in the single digits was also in March (7° on 3/7).

May 6 - The day's low was 32°, the latest date for a low of freezing or colder in Central Park.  (Three days later the high was 82°.)

 

- 1892 -

March 18 - Snow that began falling late last night continued through this morning and accumulated eight inches (the 7.2" that fell today is the most to fall on 3/18).  This was the biggest snowfall of the winter (passing a six-inch snowfall on 1/16) and came in the midst of an unseasonably cold 12-day stretch (March 11-22) in which temperatures were 12 degrees degrees below average (high/low of 34°/22°).

July 29 - Today was the end of a five-day heat wave that saw the last two days reach highs of 97°.  The average high/low during these five days was 95°/76°.  (The two days preceding the heat weave had highs of 89°). 

November 9 - Rain changed to snow and then back to rain as midnight approached.  During the time when the snow fell 2.3" accumulated, making this the earliest snowfall of two inches or more (until 1953, when 2.2" fell on 11/6).  Because of the rain that fell afterwards the snow didn't stay on the ground for long; in addition, the temperature got no colder than 35°. (The following day would see 1.31" of rain.)

December 31 - This was the eleventh day in a row with highs of 32° or colder.  The average high during this streak was 26°.  This chill, however, would end on New Year's Day when the temperature rose into the low 50s after nightfall.

 

- 1893 -

January 17 - Today was the seventh day in a row with a high in the teens.  The average high/low during this streak was 17°/8°.  This streak of bitter cold was embedded in a 13-day streak with highs of 30° or colder.

February 17-18 - A snowstorm dumped 9.1", with much of it falling on the 17th.  This was the biggest snowfall of the winter (in total there were five snowfalls of four inches or more).  Both the 17th and 18th had a high/low of 28°/17°.

March 9-10 - This was the first time since Dec. 16-17 to have back-to-back days with lows above 32°.

August 19-20 - A hurricane moved over New York City, just the second time this has happened.  A wind gust of 85 mph was clocked and 3.81" of rain fell (1.34" on 8/19 and 2.34" on 8/20).

 

Hurricane

 

August 24 - Just four days after a hurricane lashed the City a tropical storm passed to the west and dumped 3.61" of rain.

October 23 - A shield of heavy rain from a tropical storm that passed over the Delmarva Peninsula soaked the City with 2.46".

 

- 1894 -

February 26 - Today's snowfall of eight inches joined snowfalls of seven inches, six-and-a-half inches, and four inches in the past 30 days.  Today's snowstorm came the day after the coldest reading of the winter, 1° above zero (a record that was later tied in 1914).  After today the next snowfall wouldn't be until 4/12, when an inch fell.

May 25 - This was the eighth day in a row to receive measurable rain.  In total, 2.40" was measured during this streak (with about half falling on the 21st and 23rd). 

July 10 - This was the fourth day in a row with a low in the 50s (59°-56°-58°-56°).  These readings were ten degrees cooler than average.  The low on the 8th is a record that still stands. (By contrast, there have been no readings in the 50s in any July between 2010 and 2020.) 

August 20 - Today's 0.08" rainfall was the last rainfall of what would be the driest meteorological summer until 1966.  Just 4.36" was measured, which was 1/3 the average amount (the summer of 1966 received 0.05" less).

September 19 - A rainstorm that moved in yesterday evening and continued through today dumped more rain (5.16") than what fell all summer (the second driest on record).  Today's rainfall of 4.30" was a record for the date (that still stands).  At the time this was the third greatest daily rainfall (now ranked 16th).

September 20 - All of September's 8.68" of rain fell in a 13-day period ending today (with nearly half of it falling yesterday).

November 5 - Today was the fifth day in the past four weeks to pick up an inch or more of rain (1.67" on 10/10; 1.69" on 10/24; 1.06" on 10/31, 1.60" on 11/3; and 1.12" today). 

 

- 1895 -

February 28 - This was the only day of this very cold month (the second coldest February at the time, now ranked fourth) with a low above freezing.  And it was the first above freezing low since 1/16.

June 3 - This was the last day of an early season heat wave, which lasted five days.  After starting with a high of 90°, three highs of 96° followed; and today's high reached 95° (but after a cold front moved thru the temperature dropped to 63° by midnight).  The highs of June 1-3 were all records that are still standing.

June 4 - The day after the heat wave ended, today's temperature got no higher than 67°, twenty-eight degrees cooler than yesterday's high.

September 23 - A four-day heat wave, the latest on record, ended today, with a high of 97°.  This is the hottest reading ever reported in the second half of September.

November 1 - For the second day in a row the high/low was 52°/41°, and followed another pair of identical high/lows on these same dates five years earlier (high/low of 50°/37°).

December 31 - The mildest reading of the month was 60° and this was the fifth day this month that it was reached - and all were since 12/20.  It wouldn't be this mild again until 3/31.

 

- 1896 -

February 17 - With a high/low of 7°/-5°, today was the coldest day of the winter, moving ahead of the previous coldest day this winter, Jan. 6, with its high/low of 12/-2°.

March 15-16 - Less than two weeks after a snowfall of ten inches on March 2 an even bigger snowstorm dumped a foot of snow.  It began early in the afternoon of the 15th and by midnight 6.5" fell; an additional 5.5" fell the next day through midday.  Then the snow changed to rain as the temperature rose into the mid-30s.

April 18 - For the first time since record-keeping began Central Park had its first reading in the 90s in April (it was also the first day in the 90s to have a low in the 50s; the second such occurrence would be three weeks later).  This followed highs of 87° and 88° on the two preceding days.  1896 would have 24 days in the 90s, which would be the most in one year until 1936.

April 20 - This was the last day of a seven-day streak with very mild temperatures, with an average high/low of 81°/61°.  This followed a six-day stretch ending 4/8 that experienced a cold average high/low of 41°/29°.

August 11 - Today was the third day in a row with a low temperature in the 80s, the first time for this occurrence.  There have been four other streaks of this length since then: one in 1906, two in 1908 and one in 2013. 

August 13 - 1895's record for most days in the 90s, twenty-three, was broken today when the high reached 90°.  This number of hot days wouldn't be surpassed for 40 years.  Today was also the last day of a ten-day heat wave, still one of the lengthiest on record.  Four of the days had afternoon heat indexes in the 110°-115° range and nine days in a row had lows between 76°-82°.  This lengthy period of heat and humidity was responsible for the deaths of 1,500 persons in the Mid-Atlantic and Midwestern states.

November 30 - The City was shoveling out from a five-inch snowfall (that started the day before) three days after the high reached 72° (a record that still stands).

December 22-23 - One week after a snowfall of seven inches, six inches fell beginning tonight and continuing through the morning of the 23rd, followed by another round during the evening after an Arctic front moved through.  What was curious about this snowfall was the fact that it had a very low liquid content (0.25" water was measured) despite temperatures that were 32° or above last night through daybreak of the 23rd, and rain was mixed with the snow at times.

 

- 1897 -

January 28 - Snow began falling after 9 PM on the 27th and continued thru mid-day today, accumulating ten inches.  The temperature was in the low 20s throughout the storm.

February 12 - Today's snowfall of 8.5" was the fourth of six inches or more this winter.  Snow started falling shortly before daybreak and was mostly over by mid-afternoon.  The snow fell heaviest between 11 AM and 1 PM when three inches accumulated.  Temperatures were mostly in the mid-20s.

October 16 - Today's high of 87°, twenty-five degrees above average, was the warmest reading in October in the years of Central Park measurement in the 19th century (since 1869).  Although this temperature would be matched in 1919 and exceeded in 1922 (89°), this year's occurred thirteen and eleven days later than 1919's and 1922's, respectively.

December 26 - Today's three-inch snowfall was the eighth time since 1872 that an inch or more fell on this date, an average of once every three years.  Thereafter, however, the rate slowed to once every fifteen years.  (12/26 is the date in December most likely to see one-inch+ of snow.) 

 

- 1898 -

July 3 - Today's high reached 100°, the first reading in the triple digits in 17 years.  However, the wait wouldn't be nearly as long for the next reading in the 100s (July 1, 1901).

July 4 - This year's high of 96° followed July 4th highs of 85° in 1897, 78° in 1896 and 69° in 1895.

July 28 - For the the second day in a row the high/low was 80°/74°.  Coincidentally, the same two dates last year also had the same high and low (67°/64°).

September 5 - This was the last day of a six-day heat wave, with highs ranging from 90° to 93° (and the next two days had highs of 88°).  Lows on these six days were between 75° and 79°.

November 30 - Just three days after a snowstorm dumped ten inches, a snowfall of six inches accumulated today.  (And three inches had fallen on 11/24.)  The nineteen inches of snow that fell this month is the most to ever fall in November.

 

- 1899 -

January 1 - The year started snowy and quite cold as three inches fell between 2:00 and 8:00 this morning and the temperature slowly fell throughout the day, dropping from 18° to 8°.  Breezy conditions (gusts of 15-20 mph) created wind chills in the zero to -5° range.

February 12 - This was the third day in a row in which temperatures failed to rise above 9°.  Highs/lows on these days were 7°/-6° (2/10); 9°/-2° (yesterday); and 9°/4° (today).  Today was also on the snowy side with snow falling most of the day; by midnight 5.3" had accumulated.

February 13 - This was the fifth day in a row of a memorable cold wave in which highs were between 6° and 11° and lows between -6° and +6°.  In addition to the bitter cold, a blizzard that began yesterday continued today burying the City under sixteen inches of snow (10.7" fell today on top of yesterday's 5.3").  Winds that gusted between 25 and 35 mph produced wind chills around -10°.  At the time this was New York's third biggest snowfall (now tied for 17th place).  This snow came five days after a snowfall of 6.5".

 

Blizzard of feb 1899

April 6 - This was the sixth day in a row with a low of 32° or colder, tying two other six-day streaks in 1875 and 1891 as the longest on record in April (and there have been none of this length since then).  

May 4 - Today had the season's last reading in the 40s (the low of 48° was seasonable for the date), the earliest date on record for this occurrence (which still stands).  In the 19th century, the average date of this occurrence was 5/28 (in the 21st century, the date is ten days earlier).

June 20 - Today was the seventh day this month with a high in the 90s, the most of any June until 1923 (when there would be eight).  These hot days contributed to making this, at the time, the hottest June on record (until 1923; it's now tied for tenth). 

October 18 - It was a very mild day, with a high/low of 79°/67° (twenty degrees above average).  This was the sixth day of a seven-day streak in which every day's low was in the 60s, which was comparable to the average high during this time of the month (low 60s).

December 27 - The 0.1" of snow that accumulated today was the first measurable snowfall of the winter, a winter that would have 13.4" of snow in total, the least since the winter of 1878.

October 2020 Weather Recap: 'Mother Nature' Dresses Up as 'Jack Frost' for Halloween

New york in fall 2020

 

October 2020 was slightly milder and wetter than average in New York.  The month's first week-and-a-half was uneventful, with just 0.06" of rain.  Then three significant rain events soaked the City, each bringing more than an inch of rain: 1.30" fell on 10/12-13; 1.36" on 10/17 and 2.17" on 10/29-30.  The first and third rainmakers were from remnants of hurricanes Delta and Zeta.  The month ended up with 5.05" of rain, 0.65" above average.  Overall, the month was one degree above average, making it the 11th October in a row that was milder than average.  The low was nearly two degrees above average while the high was just about average (+0.1 degree). 

 

Until the end of the month the chilliest reading had been 44°, which would have been one of the mildest readings for this distinction in October (October 1946's and 1971's coolest reading was 45°; October 2007's was 44°; last October's was 43°).  But then a shot of Arctic air followed the rainstorm of 10/29-30 and Halloween morning dawned with a low of 32°, the coldest reading in October since 1988.  This was three weeks earlier than the average date of the first freezing or colder reading in Central Park.

The month's mildest reading was 74° (on 10/7), which was the coolest warmest reading in October since 2009, which also had a mildest reading of 74° (October 2009 was the last time the month was chillier than average).  The last time the warmest reading was cooler than this was in 1987, when it was 72°.  (By contrast, last October's warmest reading was a sizzling 93°.)  There were just six days with highs in the 70s (the October average is nine), none of which occurred back-to-back.  This was just the third time this has happened in October in the past 100 years.  And this October was the only one of the three that was above average temperature-wise.

 

Chart - back to back 70s in Oct

Although the month was one degree milder than average, both the warmest and chilliest readings of October were six degrees cooler than what the average warmest and chilliest readings are in October.

 

Finally, there were just eight days with mean temperatures five degrees or more above average, and four days that were five degrees or more below average.  The lengthiest streak of days that were five degrees or more above average was five (10/20-24); this streak was nine degrees above average (high/low of 69°/58°).  There were no extended periods of significantly chillier than average temperatures, but the last two days of the month were twelve degrees below average (high/low of 47°/34°).
