Weather Highlights of the 1950s

 

50s

 

What weather events/trends characterized the 1950s in New York?  The decade began with the fierce Thanksgiving weekend nor'easter of 1950.  Then four tropical systems affected the area in 1954 and 1955: Carol and Edna in 1954, and Connie and Diane in 1955.  1955 also had a torrid summer, as did 1952.  Then there was the summer of '53 that ended with an unprecedented 12-day heat wave.  Five of the six summers from 1952 thru 1957 had 100-degree readings, the greatest concentration of any decade.  The second half of March 1956 and 1958 experienced harsh winter weather while half of the Decembers during the decade had the coldest and/or snowiest weather of their respective winters. 

 

Regarding precipitation, the only snowstorm of a foot or more came at the end of the '50s when 13.7" fell on Dec. 21-22, 1959.  Finally, an extended period with below-average precipitation began at the beginning of the decade and would continue through the mid-1960s.  (Ironically, the rainiest Halloween and Easter occurred this decade, in 1956 and 1958, respectively.)  What follows, in chronological order, are nearly 100 weather highlights of the decade:

 

- 1950-

January 4 - Today's low of 59° is the mildest low temperature ever reported in the month of January, and more typical of the average low in the first week of June.  The high was seven degrees warmer, and was a record for the date (which still stands).

January 6 - The high rose into the 60s for the fourth day in a row.  Highs on these days: 60° (1/3)-66°-64°-63° (today).

January 26 - Today's high soared to 72°, the mildest reading ever reported in January (later equaled on Jan. 6, 2007).

February 21 - The morning low of was the coldest reading of the winter.  (The average low during the last week of February is in the upper 20s.)

March 4 - This was the seventh day since Feb. 20 with a low of 12° or colder.  Additionally, eight of the days had highs of 32° or colder.  The average high/low during this 13-day period was 32°/16°, twelve degrees colder than average. 

April 10 - For the fifth day in a row the morning low was 32° or colder.  The average low during these days was 29°, which was twelve degrees below average.

May 27 - With a high of 77° this was last of three days in a row with highs in the 70s.  It was the first time it happened this year, and is the deepest into a year of any year since 1940 (thru 2021).

July 31 - Today's high of 94° was the the last reading in the 90s this year, the earliest date for this occurrence since 1934, when it fell on 7/30 (1904 and 1903 also had their last 90 on 7/31).  In total, there were only six 90-degree days this summer. 

September 24 - Very chilly conditions, with a high/low of only 53°/43°.  Today's high, 20 degrees below average, was more typical of the second week of November.  Unseasonably chilly days like this in autumn are often caused by nor'easters, but today was dry under a mix of sun and clouds.

October 1 - One week after a very chilly high of 53°, today's high was 86° (17 degrees above average).

November 2 - Today's high was a record 83°, and was the fourth day in a row of extraordinarily mild weather.  Oct. 30 had a high of 79°, Halloween had a high of 76°, and yesterday had a record high of 84°.  Highs during this four-day period averaged 81°, 22 degrees above average.

November 25 - One of the strongest nor'easters of the 20th century lashed New York on the Saturday after Thanksgiving, with winds as high as 70 mph, and 1.58" of rain that fell between 6 AM and 8 PM.  Temperatures dropped steadily during the day, from 59° to 36°.  This storm produced very heavy snowfall in Pennsylvania and the Appalachians, including 27.4" in Pittsburgh (over the course of three days).

December 26 - Although it was just 2.9", the light snow that fell today in the morning and afternoon was the biggest snowfall during the winter of 1950-51.  It was also the coldest day of the winter, with a high/low of 22°/9°.

 

- 1951-

July 27 - Yesterday and today were the hottest days of the year, with both having a high/low of 94°/69°.

October 3 - The afternoon of Bobby Thomson's famed 3-run home run against the Brooklyn Dodgers in the bottom of the 9th inning that gave the New York Giants a come-from-behind win, and the National League pennant, was mostly cloudy with the temperature in the upper 60s.

November 7 - Although today's nor'easter wasn't the biggest rain producer of the year (that honor went to a storm on March 29-30 that brought 2.64"), the 2.01" that fell today poured down in less than six hours between 5:30-11 AM, while March's storm was over the course of 40 hours.  Besides this morning's heavy rain, winds gusted to 40 mph.  (And just four days earlier two inches of rain fell, but over the course of twenty-one hours.)

November 20 - For the second day in a row the high/low was a cold 35°/26° (16 degrees below average).

December 17 - Today's frigid high/low of 20°/8° (22 degrees below average) made this the coldest day of the winter of 1951-52.  Skies were clear.

 

- 1952 -

January 28 - Rain in the morning (when temperatures fell from the low 40s through the 30s) changed to snow early in the afternoon, accumulating 5.8" by early morning the next day - the winter's biggest snowfall.

February 21-26 - High temperatures for this six-day period: 38°-38°-40°-40°-42°-42°.  These readings were slightly below average.

March 9 - The low was 31° for the fifth day in a row (which followed two days that had lows of 32°).

April 2 - For the tenth year in a row measurable precipitation fell on this date - the longest such streak on record.  The amount of rain that fell today (during the late morning) was just 0.09", and was the same amount that fell last year on this date.

April 23 - This was the sixth day in a row with a high of 74° or warmer.  The average high during this streak was 78°, which was 15 degrees above average.

June 26 - Today's high/low was a torrid 100°/81°.  The low was New York's warmest ever recorded in June and the high was the earliest reading in the triple digits (next earliest would come in 1966 on June 27).  This heat came three days after a high/low of 64°/58°.

September 13 - Today's high of 94° was the hottest temperature so late in the year since 1941 when the high on 10/5 was also 94°.  Today, the last day of a three-day heat wave, was also the last 90-degree reading of the year (there were 24 in total).

December 2-3 - The biggest snowfall of the winter of 1952-53 brought 4.5".  It was a sloppy snowfall, with snow changing to rain after 2.3" fell, before changing back to snow during the morning of the 3rd, when an additional 2.2" accumulated.      

December 28 - Today's high/low of 30°/12° made this the coldest day of the winter.  And there would be just one more day this winter with a sub-freezing high (Feb. 2).

 

- 1953 -

February 2 - Today was the second, and last, day of this mild winter with a sub-freezing high, with a high/low of 29°/14°.  (A typical winter has 18 days with highs of 32° or colder.)  It came the day after the high was 52°.  

March 24 - Today saw the fourth rainstorm of an inch or more in the past three weeks.  It moved in shortly after daybreak and was over by early afternoon.  Half of the day's 1.04" rainfall fell between 11 AM and noon.  At the time, March 1953, with 8.76" of precipitation measured, was the second wettest March on record (it's since fallen to fifth place).

July 18 - This was the second day in a row with a high in the triple digits, the first time with consecutive 100°+ readings since late August 1948, when there were three such days in a row.

July 23 - Heavy rain that fell in the morning hours between 8 AM and 1 PM amounted to 2.41", breaking the previous record amount for the date, from 1938, by 0.01".

August 24 - Today was the first day of a record twelve-day heat wave.  It followed a seven-day heat wave in mid-July.

August 28 - In the midst of a 12-day heat wave, today was the first of six days in a row with highs of 97° or hotter.

September 2 - Today's high of 102° was the hottest reading of the year, and the fourth time the mercury reached triple digits this year - a first (later duplicated in 1966).  This was also just the second time a high of 100+ occurred in September (the first was on Sept. 7, 1881). 

September 4 - Today was the twelfth day in a row with highs in the 90s - New York's lengthiest heat wave on record (a record that still stands).  The average high/low during this torrid streak was 95°/74° - fourteen degrees above average.  Today was also the seventh day in a row with a low of 75° or warmer.

November 6 - Three days after the high reached 73°, 2.2" of snow fell - the earliest accumulation of two inches or more on record (4.0" fell at LaGuardia Airport).  The snow began around noon but later changed to rain (the day's high/low was 38°/30°).  This was part of an intense storm system that pummeled the City with 50 mph winds.  

November 20 - Four the fourth day in a row temperatures were very mild and nearly identical, with highs/lows of: 71°/50° today and yesterday, 72°/50° two days ago and 71°/49° on 11/17.  This compares to the average high/low of 53°/41°.

December 14 - This was the ninth day of the past eleven with temperatures ten degrees or more above average (including seven in a row between 12/4-10).  This was also a wet period, with rain falling on eight of the days, totaling 4.25", which accounted for almost all of the month's precipitation.  Today was the rainiest, with 1.46" falling during the morning from a nor'easter that moved in yesterday afternoon (dropping 0.42").  Wind gusts of 35-40 mph were reported.    

 

- 1954 -

January 10-12 - Light snow fell for 39 hours, beginning mid-afternoon on 1/10 and ending in the pre-dawn hours of 1/12.  A total of 8.4" piled up, with 2.2" falling on the 10th, 5.4" accumulating on the 11th, and 0.8" falling on the 12th.  This was the biggest snowfall in five years. 

January 16 - 12.5" of snow fell in the past seven days, with measurable snow falling on six of the days.  After today less than an inch of snow would fall for the rest of the winter.

 

NYCsnow1950s

 

January 18 - The morning low of 7° was the coldest reading of the winter.  

February 15 - Two days after the low was 11°, this afternoon's high soared to 69° under clear skies (31 degrees above average, but four degrees from the record set in 1949).

February 28 - Today's unseasonably mild high/low of 59°/41° was typical of temperatures experienced in the second half of this month.  And at 14 degrees above average, the past two weeks' high/low of 56°/38° was more typical of the first week of April.  No day during this two-week period had a temperature that went below freezing.  (At the time, this February became the mildest on record, but has since fallen to eighth.) 

April 22 - This was the third day in a row with identical, beautiful conditions - clear skies, with a high of 78° every day (compared to an average high in the low 60s).

July 31 - This was the second day this summer with a high of 100° (the other was on 7/14).  Today, however, had the warmest mean temperature of the year as its low was 77°, compared to 69° on 7/14.

August 31 - Hurricane Carol made landfall on eastern Long Island and brushed the City with gale force winds and 1.71" of rain, which began last night and continued today through late morning.

 

Hurricane carol

 

September 11 - Less than two weeks after Hurricane Carol, Hurricane Edna made itself known, dumping 3.30" of rain, with most of it falling in the twelve hours between midnight and 12-noon.  This was the biggest rainfall of the year.  This was the most rain from a tropical system in 10 years, since the Great Atlantic Hurricane dumped 9.40" over the course of three days.

October 4 - Today had the third low in the 70s this month, the most ever reported in October.  This was somewhat ironic considering that the year had 18 such days in total, well below the average of 25 days (1920-1950).

October 15 - Powerful Hurricane Hazel (a 'category 4' when it made landfall in North Carolina) affected NYC's weather as it moved through Pennsylvania, on its way to Ontario, Canada.  Although it produced minimal rain in the City, most of the 0.39” that fell poured down between 6-7 PM.  Winds gusted to 40 mph in Central Park, and 66 mph at La Guardia.  

 

- 1955 -

February 2 - The biggest snowfall of the winter, 3.6", began shortly after midnight and continued thru mid-afternoon.  The temperature fell throughout the day, from 28° to 10° just before midnight.

February 3 - The morning low of zero degrees was the coldest reading of the winter.  The last time the temperature was this cold was on Jan. 31, 1948.

 

Zerodegrees

 

April 13 - A chilly high of 46° came just two days after a high of 84°.  Skies were overcast and winds out of the northeast.

August 6 - With a high of 97°, today was the tenth day in the past three weeks to have a high of 97° or hotter.

August 7 - Every day in the first week of August had temperatures in the 90s (today's high was 93°).  The average high/low during these days was 96°/75°, ten degrees above average.  The heat wave came to an end this evening when thunderstorms from mid-afternoon onward dropped nearly an inch of rain.

August 11-13 - Hurricane Connie flooded New York with 7.11" of rain over the course of 39 hours, with the first band of heavy rain moving through late on 8/11.  Although 8/12 had the most rain (3.62"), the heaviest sustained period of rain occurred on 8/13 from 3-9 AM when 2.50" poured down.  Rain was more of an issue than wind, which gusted between 35 and 45 mph, well below hurricane force.  This was the City's biggest rainstorm since the Great Hurricane of September 1944.  And while this ranks as one of New York's biggest rain totals, LaGuardia Airport picked up five inches more rain than Central Park.

 

Conniehurricane

August 18-19 - Less than a week after the flooding rains from hurricane Connie, another tropical system, Diane, affected the region, but compared to Connie, Diane moved relatively quickly.  The first band of heavy rain moved in late on the 18th, and by 9 AM on the 19th the rain was over; less than two inches fell, but significant flooding resulted since the ground was over-saturated from the large amounts of rain from Connie.  Sustained winds got no higher than 30 mph (but winds gusted to 54 mph at LaGuardia Airport).

August 20 - The fierce heat of the first week of August returned for one last heat wave.  Today's high reached 97°, tomorrow's was 96° and 8/22 had a high of 90°.  Nearly half of the days between July 2 and Aug. 22 had highs in the 90s - and sixteen days had highs of 95° or hotter.  (This followed a cool June.)

August 22 - Today was the 25th, and last day, this summer with a high in the 90s.  All but one of the readings occurred in July and August.  Although there have been 16 summers with more days in the 90s/100s, 1955 has the distinction of having the most days with highs of 95°+, sixteen.  (Today's high, however, was 90°.)

October 4 - Skies were sunny and the temperature in the low 70s when the Brooklyn Dodgers finally won the World Series after eight tries.  And they did it against the Yankees (in seven games), making their championship all the more sweeter.

November 29 - It was a very cold day, with a high/low of only 28°/16°, twenty degrees below average.

December 21 - This was the coldest day of the winter of 1955-56, with a high/low of 18°/5°, twenty-three degrees below average.  This followed what was the second coldest day of the winter, 20°/6°, on 12/20.

December 22 - A snowfall of 2.7" during the afternoon was produced from 0.15" of liquid, which was the most to fall during what would be the driest December on record (0.25" of precipitation).  Today's amount was the most to fall in nearly five weeks (since 11/20, when 0.37" of rain fell).

December 25 - Every day between Dec. 19 and Jan. 2 had well below average temperatures except for today, which had a high of 51° under mostly sunny skies.

December 29 - The 0.3" of snow that fell this evening was the last precipitation of the month, a month in which  only 0.25" was measured - the smallest amount ever reported in December (a record that still stands), and the third driest month of all time (now ranked fifth).  Additionally, 1955 became just the second year to have three months with less than an inch of precipitation (January and July were the other two months); the other year was 1881. 

 

- 1956 -

January 2 - Temperatures were ten degrees colder than average for the past two weeks.

March 14 - It was a windy, raw and wet day.  The 1.02" of rain that fell, mostly between 5 AM and 2 PM, was a record for the date (which still stands) - besting the old record from 1913 by 0.01". 

March 18 - Less than 48 hours after a snowfall of 6.7" an even bigger storm moved in during the afternoon.  By the time snow stopped falling 24 hours later 11.6" of new snow was on the ground (3.8" of it fell today).  And today's high/low was just 30°/21°, seventeen degrees below average.

 

Snowflakes

 

March 19 - After 3.8" of snow fell yesterday afternoon and evening, an additional 7.8" fell today (thru late afternoon).  Temperatures stayed in the mid-20s all day.  In the past four days 18.3" of snow fell from two storms (6.7" fell on 3/16-17) and temperatures were 15 degrees below average.  By contrast, until four days ago just eight inches of snow had fallen all winter.

March 24 - The 1.2" of snow that fell late this morning brought the month's snowfall above 20" (21.1").  This was the fifth, and last time, that more than twenty inches of snow was reported in March (thru 2021).

March 25 - Today's high/low of 34°/18° was eighteen degrees below average. 

April 3 - This was the 23rd day in a row with colder than average temperatures.  During this streak temperatures were nine degrees below average.

April 8 - Rain from yesterday's nor'easter turned to snow after 4 AM and by late afternoon 4.2" of snow was on the ground - yet the temperature never got lower than 33°.  This was the third significant snowfall in the past four weeks, a period in which 25" of snow fell, an unprecedented amount for so late in the season.  Up until mid-March the winter had seen just eight inches.  Not surprisingly, this snowy period was also cold, with temperatures six degrees below average.

April 28 - Today's high of 84° was the first time in six months that the temperature rose above 70°.  This was also the latest date for a year's first reading of 70+ in the second half of the century.  And it came just two days after the high was just 47°.

June 14 - With a high/low of 99°/76°, today was the hottest day of the year.  The high was a record for the date, twenty degrees above average.  (This was the first summer since 1951 not to have a reading in the triple digits.)  Today was part of a four-day heat wave that was book-ended by a chilly high/low of 66°/56° on June 10 and 66°/55° on June 20. 

July 2 - With a high of 93°, this was the fourth year in a row in which the high reached the 90s on this date.

July 6 - Although yesterday was cool (high/low of 66°/58°), today was even cooler as the high/low was just 61°/57° under gray skies and winds from out of the northeast.  The day's high was 22 degrees below average.

October 8 - On the afternoon that the Yankees' Don Larsen pitched a perfect game in World Series Game 5 against the Brooklyn Dodgers at Yankee Stadium, skies were clear and temperatures were in the seasonable mid-to-upper 60s.

October 31 - 2.41" of rain fell, making this the rainiest Halloween on record (3.30" rain was measured at LaGuardia Airport).  And although the bulk of the rain occurred between 11 AM and 4 PM, when 1.74" was measured, rain was still falling in the evening hours (0.33" was measured between 7-11 PM).  Until today, October had received just 1.20" of rain.  This was the biggest rainstorm of the year.

November 1 - The day's low temperature was a summer like 65°, a record for the date and the mildest low reading in the month of November until 1971 (when the low on 11/2 was 67°) and 2015 (66° on 11/6).  Despite the day's mild start, the high temperature was only two degrees warmer because of showers and overcast skies.

 

- 1957 -

January 15 - Today's high/low was a frigid 12°/0°, making it the coldest day of the winter.  Light snow moved in after dark and continued until early afternoon on the 16th, accumulating 4.9" (two inches fell today).

January 23 - After the mercury rose to 60° during the morning, the mildest reading of the month, a slap of Arctic air slashed the temperature by 40 degrees by midnight - one of Central Park's biggest temperature drops in the course of a day.  Today was also the sixth day in a row with a high warmer than the day before (starting with a high of 23° on 1/18).

February 1 - A quick-moving snowstorm dumped 6.3" of snow between 2:00 and 11:00 PM. This was the biggest snowfall of the winter.

March 10 - For the fourth day in a row the high was 39° (eight degrees below average); however, every day had a different low temperature.  Today was the only day of the four that had sunny skies.

April 21 - This was the first Easter Sunday since 1871 to have a high in the 80s, and at 85° it was the warmest on record (until 1962).  By contrast, yesterday's and tomorrow's highs were in the mid-60s.

May 14 - I was born today in the pre-dawn hours (in the suburbs of Pittsburgh).  Although temperatures on 5/13 and 5/15 were unseasonably warm (mid-80s), today's temperatures were at seasonable levels.  Rain moved in as evening approached and it fell heavily between 9-11:00 when two inches was measured.  In total 2.55" fell and it was over before midnight (a record amount for the date until 1978).  This rainstorm accounted for two-thirds of the month's rain and was the biggest rainstorm of the year.

July 21 - Today's high reached 100°, making this the fifth summer of the past six to have at least one high in the triple digits - the highest concentration on record.  (Last year was the only year of the six not to reach 100° - its hottest reading was 99°.)  Tomorrow's high would reach 101° and would be the last 100-degree day until 1966.

 

Clipart_severe_thstorm   

 

July 22 - This was the sixth day in a row in which the high was hotter than the day before: 101° (today)-100°-97°-91°-90°-88°-83° (7/16).

December 4 - Snow that started falling late last night continued overnight, and after a five-hour break, resumed later in the morning, accumulating 8.0".  The flakes came down heaviest between noon- 3 PM, when they fell at a rate of an inch per hour.  This was the most snow to fall so early in the season since 1938, when 8.8" piled up on Nov. 24-25.  And it was the first of six snowfalls of four inches or more this winter.

 

- 1958 -

Feb. 8 - Today's high was 32°, the first of twelve days in a row in which the high was 32° or colder (today's high was the "warmest" of the streak).

Feb. 16 - Snow that began falling yesterday evening continued through this evening, totaling 7.9” (2.1” yesterday, 5.8” yesterday).  It was a wind-blown snow produced by an intense winter storm that was fueled by Arctic air overtaking the northeast as it moved up the coast. (By midnight, the temperature had fallen to 10°.)  While gusty winds of 25-35 mph buffeted Central Park, LaGuardia Airport (which reported 10.1” of snow) had winds that gusted between 50-65 mph.  South of the City, DC had more than a foot of snow, while to the north, Boston was buried by two feet.  This storm’s accumulation just missed tying a snowfall of 8.0” on 12/3-4 as the winter’s biggest accumulation (but both would be topped by the snowstorm of March 20-21.)   

Feb. 17 - It was a bitterly cold day that saw temperatures stuck in the single digits, largely due to mostly overcast skies.  The high was only 10°, which occurred shortly after midnight; the day's low of was reached 24 hours later, shortly before midnight.  This was the ninth day in a row with high temperatures colder than 30°.

Feb. 20 - Today's high was 33°, the first day since Feb. 7 with a high above freezing.  The twelve days from Feb. 8 thru Feb. 19 had a high/low of 24°/13°, thirteen degrees colder than average.

March 20 - An intense nor'easter brought winds of 35-45 mph along with heavy, wet snow that began shortly before daybreak, and continued thru midday on the 21st.  4.7" fell today and 7.1" the following day.  However, today's temperature never got colder than 33°.  Philadelphia also picked up nearly a foot of snow from this storm, which buried parts of eastern and central Pennsylvania and upstate New York with 30 to 40 inches of snow. 

April 6 - 2.19" of rain fell today, making this the rainiest Easter Sunday on record.  Most of the rain fell between 10 AM and 5 PM.

 

Heavy rain

 

June 12 - Today and yesterday had the year's first back-to-back days with highs in the 80s, the latest occurrence in the 1950-2021 period (it happened one day earlier in 1997).

July 2 - Today's high of 93° was the hottest reading of the year (and the fifth year of the past six to reach the 90s on this date).  The last time a year's hottest temperature was this low, or cooler, was in 1927, when the hottest reading was 92°.  (The next time it happened would be just two years later when the year's hottest reading was only 91°.)

July 30-August 3 - High temperatures during this five-day period were: 87°-86°-85°-84°-83°.

August 1-5 - Morning lows during this five-day period were: 67° (on 8/1)-68°-69°-70°-71° (today).

December 11 - With a high of 23°/14° (eighteen degrees below average), today was the coldest day of a 10-day cold wave (between Dec. 7-16) in which every day had a sub-freezing high temperature.  And the day seemed even colder because of overcast skies.

December 16 - This was the tenth day in a row with a sub-freezing high temperature.  During this unprecedented early cold wave the average high/low was 29°/19°, thirteen degrees below average.

December 26 - With a high of 34°/14°, today was the sixteenth day since 11/30 with a mean temperature ten degrees or more colder than average.  This nearly four-week period was nine degrees colder than average.  However, despite the cold just 3.8" of snow fell during this period.

 

- 1959-

February 2 - The morning  low of 7° was the coldest reading of the winter.

February 20 - High temperatures of the past three days: 44° on 2/18, 33° yesterday, and 22° today.  And although Feb. 2 had the coldest reading of the winter, today's high/low of 22°/8° produced the coldest mean temperature.

March 12 - A mix of snow and sleet produced the biggest accumulation of snow/ice of the winter, with 5.5" piling up by the time it ended early in the afternoon.  This icy precipitation was blown around by winds that gusted between 30 and 35 mph.

March 22 - Two days after the high reached 71°, afternoon temperatures were in the upper 20s.

June 1 - Today's chilly high of 64°, under mostly overcast skies, followed a five-day warm spell at the end of May that had highs that averaged 87° (13 degrees above average).  Today's conditions were the result of a back-door cold front that moved in from New England last night. 

June 24 - High temperatures over the past five days: 85°-84°-83°-82°-81° (today).

June 29 - Today's high of 97° was the hottest reading of the summer, but tomorrow, with a high/low of 93°/79°, had the hottest mean temperature.

July 20 - This was the rainiest day of the year, with 1.80" of rain measured.  Most of it (1.57") fell during a severe thunderstorm between 4:00 and 5:00 in the afternoon.

July 24 - All of July's rain fell during 11 of the past 15 days, amounting to 4.28".  Nearly an inch of rain fell this afternoon between 3:30 and 4:30 during a strong thunderstorm.  It was also a hot day, with the high reaching 90°

August 29 - Today was the end of a two-and-half-week period that had twelve days in the 90s (including today) and an average high/low of 89°/72° (seven degrees above average).  This hot spell, at the time, helped make this the fifth hottest August on record (it's since fallen to seventeenth).

Clipart_summertime 

September 24 - With a high of 89°, this was the third day in a row of summertime heat.  Yesterday's high was 90° and the day before that it was 89°.  The average high this time of year is in the low 70s.  Today's high was a record (which stood until 2017).

September 29 - The 0.02" of rain that fell shortly after midnight from a storm that began late last night (and dropped 0.34" from 11 PM-midnight) was the first measurable rainfall on this date since 1936.  At the time, this 22-year streak with no rain for a calendar date was the lengthiest on record, later passed by a 25-year streak on Dec. 1 for the years 1943-1967.

September 30 - After one of the hottest Augusts on record, the unseasonably warm weather continued in September, which tied Sept. 1931 as the second warmest (it's now tied for fifth).  The month's temperature patterns were divided into three ten-day periods.  The first ten days were eight degrees above average, the middle ten were six below average, and then the last ten days were nine above average.  Today, with a high of 82°/70°, was twelve degrees above average, and the low was what the average high should be.

October 1 - For the fourth day in a row the low temperature was in the 70s at a time of the year when lows are typically in the mid-50s.

October 6 - Under mostly clear skies today's high soared to 88°, twenty degrees above average, as the unseasonable warmth of August and September continued into October.  This was the hottest reading in October since 1941.

October 11 - This was the twenty-first consecutive day with above average temperatures.  During this three-week period temperatures were close to ten degrees above average, with an average high/low of 81°/65° (more like the end of August); twelve days were in the 80s. 

November 18 - Today's high/low of 33°/21° made this the coldest day of the month (19 degrees below average).  It would be five weeks before there was a colder day.

December 22 - Snow that began late in the afternoon yesterday continued thru 10 AM today, adding 10.3" to yesterday's 3.4" for a total accumulation of 13.7".  (By contrast, LaGuardia Airport picked up just 5.6".)  Snow fell heaviest between 2-7 AM when six inches accumulated.  The day's temperatures were well below average, with a high/low of 28°/17°.

December 23 - Today's high/low of 23°/9° (eighteen degrees below average) made this the coldest day of the winter of 1959-60.

December 2021 Weather Recap: Mild & Dry

 December 2021 recap

 
December 2021 was the third mildest on record (behind 2015 and 2001, and 0.1 degree ahead of 1984), and tied for fourteenth driest.  At 4.7 degrees above average, it was the most above average month of 2021 (passing October, which was 4.1 above average).  Although it ranked third for mean temperature (average of high/low), the month had the second mildest average low, and was tied for seventh mildest average high.

 

Seven days had mean temperatures that were 10+ degrees above average, and eight days had highs of 55° or milder (half of these days were in the 60s).  The mildest reading was 66° on 12/11, which was a record for the date.  Two extended periods of mild temperatures were largely responsible for the month being so mild, as Dec. 11-18 was 11 degrees above average (high/low of 56°/44°), and the last week of December was 8 degrees milder than average (48°/40°).  This was just the seventh December to have no temperatures of 32° or colder in the last seven days of the month. 

 

Six days had lows of 32° or colder (average number for December is 14), with the coldest reading being 25° on 12/20.  Only three other Decembers have had a milder reading as their coldest reading:  2015 (34°); 2012 (28°); and 1974 (26°).  And Dec. 1984's coldest reading was also 25°.  (On average, the coldest reading in December is in the upper teens; before 1970 it was in the low teens). 

 

Like November, December was quite dry, with just 1.39" of precipitation  measured.  Combined, these two months became Central Park's driest Nov.-Dec. on record.  Ironically, this dry combo occurred in one of the ten wettest years on record.  By contrast, the nine driest November-Decembers behind 2021 had about twenty inches less annual precipitation than 2021.

 

Chart - Driest NovDec 

With the exception of the last week in October, which had 4.71" of rainfall (the wettest last week of October on record), the other 12 weeks between Oct. 1 and Dec. 31 had only 3.06". 

 

December had just 0.2" of snow, which occurred in the pre-dawn hours of 12/24.  However, meager snowfall in December isn't uncommon, as smaller amounts (or none at all) have occurred in five Decembers  since 2001, and nine since 1994 (once every three years).

 

Unusually low humidity was reported on two dates - 20% on 12/14, and 14% on 12/17 (both in the afternoon).  Going back to the early 1940s, 14% is the lowest humidity ever reported in December (the previous low was 16% on Dec. 8, 1981).  Humidity levels below 25% are very rare in December (most instances of low humidity occur in March and April).

 

Finally, the month, and year, ended on a mild note as the temperature at the stroke of midnight was 51° (after a high of 55°).  This was the mildest reading during the ball drop at Times Square since 2004 (and the fifth mildest ball-drop reading on record).

November 2021 Weather Recap: Dry & Chilly

 Nov 2021 calendar

With just 1.12" of rain, November 2021 was the driest November since 1976 (the driest November on record).  The month was also 1.8 degrees chillier than average, making it the most below average month of the year (February and July were  1.7  and 1.5 degrees below average, respectively).  This November was significantly chillier than last November (the mildest on record), as it was 6.8 degrees colder - the biggest temperature drop from the previous November since Nov. 2012.  Only eight other Novembers have had a bigger drop in average temperature compared to the November immediately preceding it.

 

Chart - nov v nov

 

Despite its big difference from last November, Nov. 2021 was far from the ranks of the coldest, as it tied for 80th chilliest.  (Fun Fact: All of the Novembers between 1869-1894 were colder than Nov. 2021.)  Still, it had 14 days that were five or more degrees below average.

The month's warmest reading was 69° on 11/18, followed six days later by the coldest reading (30°).  Although this was the latest date for a temperature this mild in six years, it was the first time since 2014 that the warmest November reading failed to be in the 70s.  Of note is that this warmest reading didn't occur during the 6-day period Nov. 8-13, which was six degrees milder than average.

In October, the first low in the 40s wasn't until 10/18, which was the second latest date on record.  In November, however, the fall's first reading of 32° or colder (32° on 11/23) was close to the average date of this occurrence. 

Most of the month's 1.12" of rain fell during two rain events on consecutive days:  0.48" on 11/12, and 0.33" on 11/13.  On the 13th, an uncharacteristic precipitation type for November, hail, fell for a few minutes during a quick-moving thunderstorm.  Another type of frozen precipitation, snow flurries, was reported on the last three days of the month  - but there was no accumulation in Central Park (Newark Airport reported 0.1" on the 28th).

Days With Temperatures Stuck in the 60s

 

Stuck in the 60s

October 2021 was distinguished by having six days with highs and lows that were both in the 60s - the most such days in one month.  On average, two or three of these days occur each year, and they've occurred between May and November (ranging from 5/11 to 11/21).  September is the month most likely to have such days, and the date most likely to have one has been 9/17 (in nine years).  The year with the most  of these "stuck" days is 1903, with 13 of them (five other years have had between seven and eleven).  19 years have had none of these days, the last time being in 2019.

 

Chart - stuck in 60s by month
 

Nearly 80% of these days have had measurable rain, with 18% receiving more than an inch, and 75% a half inch or more.  The greatest rainfall on one of these days was 3.84" on Sept. 1, 1927.  (The last time three inches or more fell on a day stuck in the 60s was on Oct. 27, 2017.)  Despite the high likelihood of rain, only two of the last 15 days with temperatures stuck in the 60s had rain.  

Other observations:

  • Average high/low is 67°/62°, with average rainfall at 0.50". 
  • The most prevalent high/low is 68°/60°.  Nearly 70% of the days had highs of 67°, 68° or 69°, while  nearly 75% of the days had lows of 60°, 61°, or 62.°.
  • The warmest low on one of these days is 67°, which happened twice:  Oct. 1, 1902, and July 20, 1869. The coolest high temperature is 62°, which has occurred four times.
  • One of these days had a one-degree diurnal variation (high/low of 66°/65° on Sept. 17, 1869); 12 others had two-degree variations.

I've also written analyses about days stuck in the 30s and 70s.

October 2021 Weather Recap: 6th Mildest October Ends With Soaking Rains

 Oct 23 abingdon square park

 

After unprecedented rainfall in July, August, and September (each month had more than ten inches), it appeared a respite was in store during October, as the first half of the month was the driest since Oct. 2000, with just 0.15" of rain measured.  However, these dry conditions came to an abrupt end in the last week of the month, as 4.71" was measured - the wettest last week of October on record (and eight of the last nine days had measurable rainfall).  Much of the week's rain was produced by a nor'easter on the 25th-26th that dumped 3.69" of rain. 

 Chart - rainiest last week of october

 

The month's other storyline was its mild nighttime temperatures.  There was a record streak of lows in the 60s (13 days), which was also the month's total number of days with lows in the 60s, tying Oct. 1879 for the most on record (the average number of lows of 60+ in October is 4).  Lows during the first 12 days of the streak were in the narrow 60°-62° range; Day 13's low was 63°.  Of the eight longest streaks of lows in the 60s/70s in October, this year's record streak was the coolest.

 

Chart - streaks of 60_deg lows in october

 

Overall, the month was 4.1 degrees above average, and became the sixth mildest October on record (it ranked fourth for average low, and tied for 19th for average high).  17 days were five degrees or more above average; seven days had  below average mean temperatures.  The most above average day was 10/15, which was thirteen degrees warmer than average (high/low of 79°/63°); the most below average day was 10/1 , which was five degrees below average (67°/51°).

 

Temperatures during October ranged from 47° (on 10/19, 10/24, and 10/29) to 79° (on 10/15).  Only three other Octobers have had a smaller temperature range: 1977 (30 degrees); 2004 (31 degrees); and 1894 (31).    This mirrored September, which had a 31-degree variation, and was tied for third smallest variation.

 

In an oddity, there were six days with temperatures stuck in the 60s - the most on record for any month.  They occurred in three pairs, and were concentrated in the nine-day period between Oct. 3-11.  This narrow temperature range was largely due to persistent overcast skies.

 

The season's first low chillier than 50° was reported on 10/18, which was the second latest day for this occurrence (latest is 10/20).  Additionally, the month's chilliest reading of 47° (reported on three days), was the mildest chilliest reading on record for October (on average, the coldest reading in October is in the upper thirties).

September 2021 Weather Recap: A Record-Setting 3rd Month in a Row with 10+ Inches of Rain

 

  Lee goldberg wabc

September 2021 will long be remembered for the torrential rain that fell the night of 9/1, submerging streets, highways, subway tunnels and residences.  Nearly 50 deaths in the metro area were attributed to the storm (13 of them were in NYC).  This unprecedented deluge was produced by the remnants of hurricane Ida pushing up against a mass of cool air.  Between 5 PM and 1 AM, a little more than seven inches of rain poured down (with three inches falling between 9-10 PM). 

 

Although heavy rain had been predicted, its intensity in such a brief period of time took residents by surprise.  (And although hurricane Henri, two weeks earlier, produced an inch more of rain than Ida, it fell over the course of 48 hours). 

 

Never before had a month started with so much rain, easily breaking the previous record amount on the first day of a month, 4.98" on Oct. 1, 1913.  The 7.13" measured on 9/1 was the fifth greatest amount to fall on a calendar date.  (Earlier this year, February began with a record amount of snow for the first day of any month, 14.8".)

 

Ida flooding nyc
 

The rest of the month had slightly below average rainfall, but just enough to bring September's total to 10.03".  This was the most rain to fall in September since 2004, and it became the sixth rainiest September on record.  It followed the fourth wettest August (10.32"), and third wettest July (11.09").  Never before had Central Park had three months in a row in which each month had more than ten inches of rain. 

 

More than 90% of the month’s of rain was produced by two storms:  7.23” on 9/1-2 and 2.03” on 9/23-24.  0.77” fell on the other 26 days.

 

Looking at temperatures, September was 1.1 degrees milder than average, and was the 26th mildest September (tied with four other years).  However, it ranked 13th for mildest average low, and 55th for warmest high.  12 days in a row (Sept. 12-23) had above average temperatures, a streak of days that was four degrees above average.  The rest of the month was one degree cooler than average.

 

The warmest reading was 85° (on 9/15), the same warmest reading as last September (but it had two days with that high).  Also, both Septembers had seven days with highs in the 80s (the average is eleven).

 

Half of the days had highs between 75°-79°, which was double the average number - and the most to be in this narrow temperature range on record (second most is 13 days in Sept. 1999, 1927 and 1908).  Just five days had lows cooler than 60°, eight fewer than average.  Only Sept. 1971, 1930, 1908, and 1881 had fewer days (all had four). 

 

Finally, the month was also characterized by a narrow range in its temperature extremes.  Typically, September's chilliest reading is around 50°, the hottest around 90°, but this September it ranged from 54° (on 9/29) to 85° (on 9/15).  Only two other Septembers have had a range that was smaller.  (The greatest range in temperatures in September was 55 degrees in 1929, ranging from 44° to 99°.)

August 2021 Weather Recap: Henri Rescues August From "Dullsville"

 

 Hurricane henri aug 2021

 

August was the fourth wettest August on record, but until 8/21 the month had been a dry one, with rainfall 50% below average.  Then, Hurricane Henri produced 8.19" of rain over three days (Aug. 21-23), accounting for nearly 80% of August's 10.32" of rain.  (The other 28 days of the month had just 2.13".)  This was the second month in a row with more than ten inches of rain (July had 11.09", making it the third wettest July),  just the second time this has happened (however, the first time, in March and April 1983, is disputed since the rain gauge in Central Park wasn't functioning properly for much of the year).  Although August's rainfall was less than an inch below that of July, its number of days of measurable precipitation was half as many (nine vs. eighteen).

 

Chart - rainiest back to back months
 

One out of four Augusts have been warmer than July, and August 2021 was one of them (77.5° vs. 76.0°).  The month was 1.4 degrees above average, making it the City's 17th hottest August (out of 153).  However, there was a disparity in rankings of the average high and low, as only five other Augusts have had a warmer average low than this August (2.2 degrees warmer than average), but the average high (just 0.6 above average) was ranked much lower, at #39.  This difference in rankings wasn't unique to this August, as the trend during the 2000s has been for overnight temperatures to be more above average than daytime readings (one of the effects of global warming).

 

After the first five days of the month were five degrees below average, the rest of the month was three above average (with only five of the 26 days having cooler than average mean temperatures).  August had five readings in the 90s, one more than July, and it had five more days than July with lows of 75° or warmer.  August's days in the 90s were comprised of back-to-back days on Aug. 12-13, and a three-day heat wave two days after Henri's departure (Aug. 25-27).  The month's hottest reading was 94° on 8/13.

 

Finally, this was the eighth year in a row in which August had no readings in the 50s.  The coolest temperature was 63° on 8/2.  (Meanwhile, July's streak of 12 years with no lows cooler than 60° was broken this year).

July 2021 - Third Rainiest July Keeps Mid-Summer Heat in Check

 Noahs ark in water

With 11.09" of rain measured in Central Park, July 2021 became the third rainiest July on record (behind 1889 and 1975), and 15th wettest month overall.  This was New York's first month with ten inches or more of precipitation since June 2013 (10.10"), and the most to fall in any month since August 2011, when 18.95" flooded the City (the greatest monthly amount on record). 

 

A little more than half of July's rain fell on three days between July 8-12: 2.27" on 7/8; 2.06" on 7/9, and 1.42" on 7/12.  The amounts of 7/8 and 7/9 set records for the dates.  8.49" of rain fell in the first 12 days of the month (and 9.14" if 6/30 is included), then 2.60" fell thereafter (which was slightly below average for that period). 

 

There were 18 days of measurable rain, which was the second greatest number of days with rain in July.  July 1871 had twenty days, but just half the amount of rain as July 2021.   (Of the 27 months with ten inches or more or precipitation, the average number of days of measurable precipitation is 13.) 

 

Besides being rainy, this was the coolest July since 2009 (and 0.1 degree cooler than July 2014).  When all Julys are considered, July 2021 is in the middle of the pack, temperature-wise, with 54% being warmer.  The combination of a warmer than average June (+2.3 degrees), and July being 1.5 degrees cooler than average, placed these two months closer together (1.7 degrees) than any June/July combo since the summer of 2001 (when July was just 0.3 degree warmer).  Looking at average high and low, July's average high of 83.0 was just 0.5 degree warmer than June's, while the low of 69.0 was 3.0 degrees milder.  Because many days had dew points in the 68°-73° range, the air often felt oppressive rather than cool.

 

So close_colbert
 Chart - july close to june

For the first time since 2009, a reading in the 50s occurred in July - 59° on 7/3.  And on 7/3, the high was only 66°, which was the first high cooler than 70°in July since 2013, and the coolest reading in July since 2005 . The month's coolest and hottest readings were three days apart as a high of 92° occurred on 7/6 (and the 59° reading came three days after June's hottest temperature, 98°, on 6/30).

 

July had four days in the 90s, half as many as June, and the fewest such days in July since 2014, which had three.  (Seven of the Julys between 2000-2009 also had four or fewer days in the 90s.)  Although the number of days of 90+ was half the average for July, the number of lows in the 70s, 16, was an average am0unt (but ten fewer than last year's record amount).

 

July had 8.47" more rain than June's 2.62", but there have been ten other instances where the disparity between two months was even greater (looking only at wet months preceded by dry ones).  The greatest difference occurred in  Sept-Oct 2005, when October had 16.73", which was 16.25" more than September's bone-dry 0.48".

Finally, after suffering through sweltering heat, and a nighttime thunderstorm on the last day of June, the last day of July couldn't have been more different, as skies were clear and temperatures on the cool side (high/low of 77°/60°).  While 6/30's high of 98° (14 degrees above average) was the hottest reading on that date since 1964, 7/31's low of 60° (ten degrees below average) was the chilliest since 1956.

June Weather Recap: Two 4-Day Heat Waves Make June 2021 One of NYC's 10 Hottest

 City sunflower 2021

With a scorching high of 98° on the last day of the month (along with a heat index of 106°), June 2021 became New York's ninth hottest June.  This was Central Park's hottest temperature since 2013, and the hottest reading in June since another 98° high in June 1994.  6/30 was also the last day of the month's second four-day heat wave, which was just the second time there were two heat waves of this length (or longer) in June (the other was in June 1943, the hottest June on record). 

 

The month's eight days with 90+ highs were the most in June since June 1991 (which had nine).  Only four Junes have had more hot days: 1943 (11), 1966 (10), 1925 (9) and 1991 (which was slightly cooler than June 2021, ranking as 14th warmest).

 

The month had nine days with lows in the 70s, tying it for ninth most in June.  The month's five days with lows of 75° or warmer was the most since there were six in June 1943.  (June 1909 had the same number as this June.)  Finally, in the years since 1940, the low of 76° on 6/6 was the fifth earliest date for a low this warm.

 

Ironically, despite the month's warmth, this June had the latest occurrence of a reading in the mid-50s since 1995, occurring on 6/23 (54°).  This was the coolest reading of the month (twelve degrees below average).

 

The month's two four-day heat waves were three weeks apart - June 6-9, and June 27-30.  The first heat wave averaged a high/low of 91°/74° (13 degrees above average), the second was 94°/75° (nine above average).  Both heat waves had a day with significant rainfall at night, 0.47" on 6/8, and 0.65" on 6/30.  Without these heat waves, the other days of the month were one degree cooler than average.

 

Besides the high of 98°, the last day of June was also the rainiest day of the month (0.65").  If it hadn't been for this rainfall, this would have been the second June in a row with less than two inches of rain, something that hadn't happened since 1978 and 1979.  These nighttime thundershowers cooled the temperature to 73°, erasing the day's morning low of 80°.  (If that sultry low had remained the day's low, this would have been the seventh, rather than ninth, hottest June.) 

 

With eight days of 90+ readings by 6/30, 2021 joined 20 other years (since 1869) to have this many by that date (1991 had the most - 15).  The last time there was this many by this date was in 1994.  Prior to that, between 1923-1994, this many days in the 90s by the end of June occurred much more regularly, once every four years.

 

Finally, in an interesting contrast, while the last four days of June had highs in the 90s (eleven degrees above average), the last four days of May all had lows in the 40s (ten degrees below average).

May 2021 Weather Recap: Close to Average Temperature & Rainfall Despite Very Chilly & Wet End

 Wet and chilly memorial day weekend

Last May, the month's weather highlight was an Arctic outbreak in the second week of the month that produced the coldest reading in May (34°) since 1891.  May 2021, meanwhile, experienced one of the chilliest ends of any May, as May 28-31 tied May 1884 for the latest four-day streak with lows in the 40s.  This chilly ending was responsible for the coolest three-day Memorial Day weekend on record.

Despite the month's chilly ending, an extended period of above-average temperatures from May 15-27,  that was six degrees milder than average, kept the month close to average, temperature-wise.  And a very wet May 28-30, in which 2.57" was measured, balanced what, up until then, had been a dry May (these three wet days had as much rain as the previous six weeks).  So, when all was said and done, the month was very close to average on both the temperature and rainfall fronts (-0.3 degrees, and +0.40").

 

Before May's chilly and rainy close, six days in the 10-day period between May 18-27 had highs in the 80s.  This included highs of 89° and 88° during the weekend of 5/22 and 5/23; by contrast, the following weekend had highs of 51° on both days.  This reading (which was eight degrees colder than the average low for these two dates) tied a record for the coolest high on 5/29, and set a new record (by four degrees) on 5/30.

 

Besides the last four days of the month, which were 13 degrees cooler than average, there was an eight-day period from May 5-12 that was five degrees below average.  (However, the chilliest reading of the month, 42°, was on 5/1.)

 

Finally, the last six days of the month all had measurable precipitation, the longest rainy streak since one of eight days in May 2019 (5/10-17).  However, this year's streak had a touch more rainfall (2.68" vs. 2.56").

April 2021 featured ten days with highs of 70° or warmer, the first time April reported this many since 2010, and just the tenth time overall.   (The average number of such days in April is six.)  This above average number of warm days resulted in the month's average high being 2.5 degrees milder than average (its average low was 0.7 degrees above average).  Of the ten Aprils with ten or more highs of 70° or warmer, just four rank among the ten mildest Aprils.  This April ranked 22nd (out of 153).

The month's  coldest temperature was 28° (on 4/2), which was the coldest reading in April in five years.  And although this April was significantly milder than April 2020 (which was 2.7 degrees colder than average), its coldest temperature was eight degrees colder.  The warmest reading was 85°, which is close to what the warmest reading in April has averaged since 2000 (last April was an exception, with a mildest reading of just 68°).   This reading came five weeks after the year's first reading in the 80s (82° on 3/26), and it was the warmest reading since Sept. 5.  

 

The month's warmest reading was on 4/28, but the most above-average period of the month was the seven days between April 4 and 10, when temperatures were eight degrees above average (high/low of 68°/49°).  In total, the month had twelve days that were five degrees or more above average, and five that were five degrees or more below average.  

 

Another highlight of the month occurred on 4/8 when the humidity dropped to 7% during the afternoon - the second lowest level this century.  Finally, April's rainfall of 2.69" was nearly two inches below average.  All but 0.05" fell between 4/11 and 4/30.
