Today in New York Weather History: January 20

 

1918

After soaring to 59° shortly before daybreak the temperature fell sharply all day and was down to 18° by midnight (on its way to 8° by 8:30 AM tomorrow).

 

1937

A sloppy winter storm with snow, sleet and freezing rain produced 5.7" of snow, which fell mostly during the afternoon - it was the biggest snowfall of the winter.  During the evening the snow changed to freezing rain.  This winter storm followed three days with highs in the 50s.  (And the next two days would have highs in the upper 40s.)

1970

The 0.25" of precipitation that fell between 7 PM this evening and 3 AM the following morning, in the form of snow (three inches), was the most to fall all month, a month which saw only 0.66" of precipitation (most of it snow).  At the time, this was the driest January on record (later broken in 1981 when just 0.58" was measured). 

1978

Snow, that began yesterday evening, fell at a rate of an inch an hour between 2:00 and 7 AM, and by 2 PM 13.6" had piled up.  This was New York's biggest snowfall since the "Lindsay snowstorm" of February 1969.  (However, in less than three weeks this storm would be overshadowed by the great blizzard of February 1978.) 

 

1987

Today was the first day this winter with a high temperature of 32° or colder, the latest date for this occurrence in the 1970-2020 period. 

1994

The morning low of zero degrees was a record for the date but a two-degree "warm-up" from yesterday's low of minus 2°.  The photo below shows a mostly ice-covered Hudson River as seen from my office at Worldwide Plaza on West 50th St.

 

1995

During a rare January thunderstorm, 0.44" of rain fell in just 30 minutes (10:18-10:48 AM) and 0.76" in an hour (10-11 AM).  The day's total rainfall of 1.41" was a record for the date.  This came near the end of a nine-day period (1/13-21) in which temperatures were 17 degrees above average.

2000

The first measurable snow of the winter fell today, a steady light snow that moved in during late morning and continued thru much of the afternoon; 2.5" accumulated.  This came just two years after the winter of 1998's first snowfall fell on Jan. 18.  Today was also the 20th day in a row in which no low temperature was duplicated.

2019

After a rainy morning (0.88" fell) Arctic air swept in, dropping the temperature from 42° late in the morning (the first reading in the 40s since 1/9) to 14° shortly before midnight.  This was the coldest reading in more than a year, since a low of 5° on Jan. 7, 2018.  Howling winds after dark produced wind chills around 0°.  (And the temperature would fall ten more degrees by 9 AM on the 21st.)

Remembering New York's Top Weather Stories of 2019

After pondering the various weather events that occurred in New York over the course of 2019, my choice as the year's biggest story is a sizzling hot day in October.  Although there had been 90-degree readings in October before, they were a long time ago - in 1927, 1938, 1939 and 1941.  (By comparison, April had fifteen readings in the 90s in the years after 1941.)  But on Oct. 2 the mercury soared to 93°.  It was somewhat ironic that this hot autumn day occurred in 2019 because the year's first 90-degree reading wasn't until the end of June, which was a month behind schedule, and there were no 90-degree readings in September.  What follows are the other meteorological highlights that were candidates for top story of 2019:

 

HOT & COLD

Two days in January had especially cold readings: 14°/4° on Jan. 21, 16°/2° on Jan. 31.  These were among the five coldest days in the past 25 years.  At the other end of the thermometer, the year's hottest reading was 95°, which happened during a July weekend, 7/20-21.  (LaGuardia, JFK and Newark topped out at 100°, 99° and 99°, respectively).  Both days also had lows in the 80s (and during the afternoon of 7/22 the dew point reached an absurdly high 79°, the highest in nearly 40 years.)  Although this reading was well below the hottest temperatures experienced in past summers, the month ended up being New York's 11th hottest July on record, due largely to consistent warmth throughout the month, not only during the daytime but at night as well (the month had July's fifth warmest average low).

 

SNOW DROUGHT

2019 wasn't a snowy year, with just 16.6" measured, the least snow since 2012 (the years 2013-2018 averaged 40 inches of snow).  Much of the year's snow was concentrated in the first four days of March, all which had an inch or more of snow - the first time a streak of this length occurred in any month of any year.  The 10.4" of snow that accumulated on these four days accounted for well over half of calendar year 2019's snowfall .

 

DAYS OF PRECIPITATION WELL ABOVE AVERAGE FOR SECOND YEAR IN A ROW

After 2018 established a new record for most days with measurable precipitation, 2019 followed with the fourth greatest number of days.  But while 2018 was the fourth wettest year on record 2019 ranked 28th.  May had 19 days of precipitation, which was the second most for any month (the most is 20 days, in July 1871 and May 1888); this followed 18 days of precipitation in April (most ever for that month).

 

MOTHER'S DAY HAD WORST WEATHER OF ANY HOLIDAY

A nor'easter brought a cold, all-day rain that amounted to 1.32".  Temperatures fell into the 40s around daybreak and stayed there for the rest of the day; this meant afternoon readings were 25 degrees colder than average.

 

JULY RAINSTORMS BROUGHT BIGGEST RAIN TOTALS

The year's two biggest rainstorms came five days apart in July as 2.33" poured down on July 17-18 (from tropical storm Barry) and 2.19" fell on July 22-23.

 

THANKSGIVING WEATHER

Blustery conditions on Thanksgiving Day (winds gusted between 25-37 mph) forced officials in charge of Macy's Thanksgiving Parade to order its famous balloons be flown much lower than usual, with some nearly scraping the pavement.  (For most parade goers, however, the wind was more bearable than the previous year's frigid temperatures.)

 

DRY MOMENTS

Despite all of the days of precipitation, and three months with more than six inches of rain, there were moments when the air dried out.  For instance, September was among the ten driest on record, with just 0.95" measured - the first month with less than an inch of rain in six years.  Then there were a number of days with extremely low afternoon humidity levels: March 24 and 26 (13% and 14%), Sept. 19 (15%) and Nov. 16 (13%).  Lastly, despite December being one of the ten wettest, it also had a ten-day period with no rain or snow, tying a ten-day period in September for longest precipitation-free streak of the year.

 

YEAR ENDS WITH WET DECEMBER FOR SECOND YEAR IN A ROW

Finally, December was the wettest month of the year (7.09"), just the third December to gain this distinction.  The first two weeks were particularly soggy, with five inches measured - the third greatest amount to fall in the first two weeks of December.

December 2019 Repeats December 2018's Wet Conditions

December 2019 was the wettest month of the year and fifth wettest December on record (7.09" was measured).  Much of its precipitation fell in the first two weeks of the month.  In fact, the 5.05" that was measured during this period was the third greatest amount to fall in the first two weeks of any December.   Looking at temperature, the month was slightly above average (+0.8°).  Although Dec. 1-22 was 2.5 degrees colder than average, the rest of the month was mild enough (+9 degrees), to push the entire month into the above average column.  The mildest reading of the month was 58° (on 12/10), making this the first December since 2005 not to have any readings of 60° or warmer.  The coldest reading, 16° on 12/19, was three degrees colder than the typical coldest reading of December.  The 19th was also the only day that had a high of 32° or colder (25°).

 

Despite the month's surplus precipitation there were ten consecutive days with no measurable precipitation (Dec. 19-28).  This matched a 10-day stretch in September - the longest dry spells of the year.  (September 2019 had just 0.95" of rain, making it the eighth driest September on record).  Coincidentally, last year's wet December (ninth wettest) also had a ten-day stretch with no precipitation.

 

Being the wettest month of a year is rare for December.  Before 2019 only two other years had December as their wettest month - in 1957 (when 5.26" was reported) and in 1973 (9.98" was measured).  Another distinction for Dec. 2019 is that it was just the 13th month to have more than seven inches of rain as well as a streak of 10 or more days without any measurable precipitation.  (The longest streak during one of these months was thirteen days in June 2006).

 

 

In addition to the soggy first two weeks, other December highlights included the season's first measurable snowfall on 12/2 (1.3" fell) and an out of the ordinary snow squall of 10-15 minutes during the afternoon of 12/18 that ushered in the coldest weather of December (0.4" accumulated, and an additional 0.3" fell from a snow shower a few hours later).  Additionally, the first four days of the month had highs/lows stuck in the 30s, just the sixth time there's been a streak of this length or longer.

 

 

Finally, December 2018 and 2019 joined December 2008 and 2009 as the second pair of consecutive years to be among the ten wettest Decembers (2008 is #4; 2019 is #5; 2008 is #9; and 2018 is in tenth place).

In a Rut: Temperatures Stuck in the 30s

This post was inspired by the first four days of December 2019, all which reported highs & lows in the 30s.  The last time there was a streak of this length was in January 1998, when there was one of five days.  Although days "stuck in the 30s" aren't rare, as a typical year sees a half dozen of them, strings of three days or longer happen infrequently, about once very five years.  Not surprisingly, nine out of ten of these days have occurred from December thru March, with December having the most. (They've occurred as early as Oct. 26 and as late as April 11).

 

 

More than half of these days have reported measurable precipitation (57% to be exact); one in four have reported measurable snow.  Since many of these days have temperatures around freezing (two-thirds have a reading of 32° or colder for at least part of the day) the type of precipitation that falls is a mixed bag (i.e., rain, freezing rain, sleet and wet snow).  Often the type of snow that falls doesn't readily accumulate on paved surfaces if the temperature is above freezing.  And although temperatures in the 30s are far from frigid, the fact that they're often accompanied by overcast skies or precipitation makes these days feel raw and colder than the air temperature. 

 

 

The most precipitation to fall on one of these "stuck" days was 2.03" on March 29, 1984 (high/low of 36/34); 1.8" of the precipitation was snow.  Additionally, there have been four other storms that produced two+ inches of liquid precipitation that crossed over to other days - in Jan. 1987, March 1967, Dec. 1930 and Dec. 1914 (all days were in the 30s).  The biggest of them all produced 3.49" of precipitation and lasted three days during the first week of March 1967; two inches of snow fell on the first day of the storm. 

 

Speaking of snow, the most to fall on a day with temperatures in the 30s for its entirety was ten inches on Feb. 10, 2010 (high/low was 34/30).  And 11.8" fell from a storm that crossed over into a second day on March 21-22, 1956.  In addition to these snowfalls there have been nine others that dropped six to ten inches (most recently on March 21, 2018 when 8.2" fell on a day in which the high/low was 39/31). 

 

 

In the years since 1900, the longest streak of days stuck in the 30s is five, which has happened three times: in Jan. 1998, Dec. 1970 and in Dec. 1914.  The most in one winter was 20, which occurred in the winter of 1997-98.  Every winter except one, 1924, has had two or more days stuck in the 30s. (The winter of 1924 had one day.)  Finally, the most in one month is eight, which has happened twice - in January 1987 and January 1998.  (December 2019, thru 12/19, has had seven.)

 

 

If this analysis leaves you cold, I also posted one last year about days stuck in the 70s.

 

 

 

 

November 2019 - Cold & Dry

November 2019 was the 31st coldest November and 32nd driest (going back to 1869).  It tied November 2012 as coldest November of this century.  Nine days had lows of 32° or colder, the most since 2013 and well above the 21st century average of three.  Looking at precipitation, the first 17 days of the month had just 0.25" of rain.  1.95" was measured for the entire month (more than two inches below average), with much of the rain concentrated during the seven days between 11/18-24.  Despite the cold temperatures no snow fell.  Other interesting aspects:

 

• The 11-day period between 11/8-18 was ten degrees below average (six days had mean temperatures that were 10-20 degrees below average).  The month's other nineteen days had temperatures that were close to average, resulting in the month being 3.8 degrees colder than average overall (its average low was 4.5 degrees below average).  This was the most below average of any month since March 2015 (-4.4 degrees).

• Half of the Novembers that were colder than Nov. 2019 occurred in the 19th century (1869-1899).  Looking at the past 100 years Nov. 2019 tied for ninth coldest.

• The mildest reading of the month was 71° in the early hours of 11/1; the coldest reading was 23° on 11/13.  That reading was a record for the date and followed a record low of 25° the day before that. 

• Since 1970 November's mildest reading has averaged 71°, which was the same as this November.  However, the second mildest reading has averaged 69°, but this year's was only 62°, which was the chilliest second mildest reading since November 1977.

• Gusty winds on Thanksgiving Day somewhat marred Macy's Thanksgiving Day Parade.  Up until a few hours before the parade started it was uncertain whether its famous balloons would be permitted to float high above the streets of Midtown Manhattan, but it was decided to let them participate at a much lower height than usual.  Wind was the only issue as temperatures were at seasonable levels and there was no rain.

 

 

• On 11/13 the relative humidity at mid-day fell to an exceptionally low 13%, the lowest humidity reported in November in the years of the 21st century.  It was also the only date outside of March and April with a humidity level this low.

• Last November, 3.3 degrees colder than average, seemed more wintry than this November because it featured a 6.4" snowstorm and had one of the coldest readings ever reported in November, 15°.  It also was one of the wettest Novembers.  While its average high was 0.9 degree colder than this November, it's average low was 1.9 degrees milder.  Like Nov. 2019, the equally cold Nov. 2012 was dry (1.81").  However, a big difference was that Nov. 2012 had a snowfall of 4.7" on 11/7-8 (the earliest accumulation of four inches or more).

A Reading in the 90s Makes October 2019 Memorable in New York

Although above average rainfall characterized October 2019, a day of sizzling heat at the beginning of the month is likely what many New Yorkers will remember.  After having no days in the 90s in September, the high on 10/2 was a torrid 93°, 24 degrees above average - and the first 90-degree reading in October since 1941.  (The high the next day, however, was thirty degrees chillier.)  As for the rain, 6.15" was measured, the most in October since 2006, and the second rainiest month of the year (May had 6.77").  A little more than half of the month's rain fell on two days: on 10/16, when 1.83" fell, and 10/27 (1.38").

 

The month was three degrees warmer than average and was the 24th mildest October on record (but it ranked 12th for average low).  And although it had just a few days with highs of 70° or warmer or lows in the 60s, the month also had very few days with highs in the 50s or lows in the 40s (the chilliest reading was 43° on the 19th).  Similar to September, October ended with 11 days in a row with above average readings (averaging six degrees above average).  Temperatures between 10/3-20 were average while the other 13 days of the month were seven degrees above average.

 

In the years since 1900 three out of four Octobers have had their chilliest readings in the 30s or 20s.  October 2019 joined only five other Octobers whose chilliest lows were 43° or milder.  (The mildest reading to be the chilliest October low is 45°, which happened in 1945 and again in 1971.)  The typical chilliest October temperature is around 38° (fourteen Octobers since 1900 had chilliest readings of 32° or colder; the last time it occurred was in 1988).

 

 

The low on Halloween was 60°, 15 degrees above average.  It joined 10/1 and 10/2 as the only days in October with lows in the 60s.  The high of 71° on 10/31 was the warmest reading on the holiday in ten years, when the high was also 71°.  It was also the mildest reading since 10/14.  (And although 10/31's high of 71° was 22 degrees cooler than 10/2's, its low was just three degrees lower.)

 

 

Finally, October's plentiful rainfall followed a very dry September, in which just 0.95" was measured.  And while this was a decided contrast, it wasn't nearly as extreme as Sept/Oct 2005 when  October saw 16.73" after a paltry 0.48"; April/May 2007, when April had 13.05" and May had just 1.88"; and Aug/Sept 1882, when September had 16.85" and August only 1.14".

September 2019 - One of 10 Driest Septembers On Record

September 2019 was the first month since October 2013 to have less than an inch of rain; it was the eighth driest September on record (0.95" was measured).  Thru 9/20 the month had average temperatures; then the last ten days were eight degrees warmer than average, resulting in the month being 2.4 degrees above average (24th warmest since 1869).  Although it was warmer than average, the month had just one low of 70º+, the fewest in September in ten years (there were none in 2009).  It was also the first September since 2011 not to have any highs of 90° or hotter. 

 

This September added to the record set last year when last September was the fourth in a row with an average temperature of 70.0 degrees or warmer.  September 2019, however, was the "coolest" of the five.  However, a record that was tied last September, the sixth September in a row with a high in the 90s, wasn't broken this year as the hottest temperature this September was 89°.  (It occurred on 9/23 - the same date as the month's only low in the 70s).

 

 

Two-thirds of September's paltry amount of rain fell in the first six days of the month, split mostly between Labor Day (when 0.30" fell mid-day, the most to fall on the holiday in sixteen years) and 9/6, when the most northernmost band of hurricane Dorian dropped 0.27" in less than an hour during mid-afternoon.

 

 

Finally, humidity of 15% or lower occurs very infrequently in New York, and when it has happened it's been confined to March and April (in the years since 2000) - until 9/19, when it dropped to 15% for a few hours that afternoon.  The last time the humidity was this low in September was on Sept. 11, 2001, when it bottomed out at 16%.

One Word Sums Up New York's Weather in August 2019: 'Uninspiring'

August, much like June, had close to average temperatures (+0.3 degrees).  Perhaps the most interesting story during this month of uneventful conditions was the twelve-day period from Aug. 17 thru 28 in which the first six days were very warm (average high/low of 89°/73°, including the month's three days in the 90s) followed by six days that were pleasantly cool (high/low of 75°/64°).  The month's three days in the 90s went no higher than 90° (something which has occurred just once before, in August 2014).  Finally, this was the sixth consecutive August with no readings in the 50s.

 

The month had somewhat below average rainfall.  The 3.70" that was measured was the least precipitation since February's 3.14".  Much of it fell on three days: 1.18" on 8/7, 0.64" on 8/18 and 1.01" on 8/22.  (Although August 2019 had less than average rainfall there were six drier Augusts in the 2010s.)  There were ten thunderstorms or brief periods of heavy rain in the three weeks between 8/3 and 8/22.  They occurred mostly in the afternoon and evening and were responsible for the day's lows occurring in the evening rather than at around daybreak.  Without these cool downs there would have been five days with lows of 75° or warmer rather than one.

Cooling Thunderstorms Prevented July 2019 From Ranking Among 10 Hottest Julys

As July 2019 came to a close it appeared the month was about to join three other Julys from the 2010s ranked among New York's ten hottest Julys.  As late as 3:00 PM on 7/31 the day's high/low was 87°/76°, and if that low temperature held  the month would have tied July 1966 as ninth hottest (both with average temperatures of 79.66°).  But then mid-afternoon thunderstorms erupted between 3-4:30 and the temperature tumbled to 70° - making it the day's new low.  This brought July 2019's average temperature down to 79.56°, pushing it to eleventh place, 0.05 degree cooler than July 1949 (79.56° vs 79.61°).  However, as a consolation prize, July 2019's average low was warm enough for it to rank fifth in this category. 

 

Other observations:

• Besides the thunderstorms of 7/31, thunderstorms on 7/17 and 7/22 also resulted in lows that occurred in the evening.  Much of the month's rain fell from these two rainstorms, with 2.33" falling on 7/17-18 and 2.19" on 7/22-23.  So far this year these are 2019's two biggest 24-hour rainfalls.  And with 5.77" measured July 2019 became the second rainiest of the fifteen hottest Julys.  This was after just 0.08" of rain fell in the first ten days of the month.  (Last July, which had nearly seven-and-a-half inches of rain, also started out dry, with just 0.24" measured in the first eleven days of the month.)

 

 

• There were ten days in July with highs of 90°+ (average is eight), making it the sixth July of the decade to have this many, the most of any decade.

 

 

• This July joined 36 others that have had ten or more days with highs of 90°+.  However, July 2019's ten torrid days had the "coolest" average temperature, tied with July 1887 (91.7°).  July's hottest temperature, 95° on 7/20 and 7/21, was one of the coolest readings for hottest temperature among the Julys with ten or more 90°+ days; those other months' hottest readings averaged 99.4° (half of them had hottest readings in the triple digits).  But the average low on July 2019's hot days, 74.9°, was warmer than 24 of the 36 other Julys. 

• July 1's low of 65° was the "coolest" reading of the month.  Only July 2008 has had a warmer "coolest" reading (66° on three dates).  The month had two days with lows in the 80s, which were the same two days that had highs of 95°.  It joined ten other Julys with two or more lows in the 80s.  Lastly, this was the unprecedented tenth year in a row in which July had no readings in the 50s.

• What was notable about July 2019 was its consistent warmth but absence of extreme heat (excluding heat indexes).  26 days had highs of 85° or warmer, one shy of the July record, which has happened in three years: 1944, 1966 and 1993 (the average number of such days is 17).  Additionally, 24 days had lows of 70° or warmer, the second most on record; only July 2010 had more, with 25 (the July average is 15).

• I refer to the week of 7/16 as as New York's "Hell Week" because, historically, it is the week most likely to have readings of 90° or hotter.  And this year six of July's ten 90-degree highs were concentrated during this week.  The one day not in the 90s, 7/18, was stuck in the 70s all day (high/low of 79/71) due to overcast skies and northeasterly winds.  Ironically, 7/18 has been the date most likely to have a high in the 90s/100s.

 

 

• July was the third month in a row with more than five inches of rain, joining three other years which had five or more inches in May, June and July (1984, 1989 and 2009).  Although the 18.05" that was measured was nearly five inches above average it was significantly less than what fell in the other three years.

 

• Finally, for the fifth year in a row 4th of July had a warmer high than the previous year.  And with a high of 90°, this year's was the hottest 7/4 since 2012.

Recap of June 2019's Weather in New York

June 2019, like June 2018, was 0.2 degrees above average (this followed a May that was 0.2 degrees below average).  However, this June's average high was 0.6 degrees cooler than last June while its average low was 0.6 milder.  The first half of the month was 0.7 degrees cooler than average while the second half was 1.2 degrees warmer.  Similar to last June the warmest period came at the end of the month, with the four-day period between 6/26-29 six degrees above average (high/low of 89°/72°); this included the year's first high in the 90s (91° on 6/29, a month later than usual).  Although the month was average in the temperature department rainfall was an inch above average (5.46"), making this the rainiest June in six years.  The biggest daily rainfall was 0.86", which happened twice, on 6/2 and 6/25.  On both dates the rain poured down in less than an hour.  Here are a few other highlights:

 

• Besides the year's first reading in the 90s being a month behind schedule, the year's first low in the 70s, on 6/25, was three weeks later than usual.  It was the first of five days in a row with a low in the 70s (6/30 looked to be the sixth but the temperature dropped to 69° as midnight approached).

• Father's Day and Gay Pride Day both were seasonably warm (high/low of 80°/65° and 83°/69°) but Gay Pride Day had more sunshine.  Both days saw a shower, but the shower that fell on Gay Pride Day (0.06") was more disruptive because it fell mid-afternoon during the parade (the first rain to fall during the parade in eleven years) while the shower on Father's Day (0.04") was shortly before daybreak. 

• May and June had 12.28" of rain, making this the 11th wettest May/June combo on record. The 10 years with more all occurred in the years since 1948.  (Greatest amounts were 19.03" in 1989, 18.10" in 2013 and 17.69" in 1972.)

• 2019 became the 36th year (since 1869) to have one or fewer days in the 90s thru June 30.  (The average number is four).  And of the fifteen years (excluding this year) that had one day in the 90s during this period the total number of such days for the year averaged eleven (with 1955 and 2015 having the most, 25 and 20, respectively).

• Although the coolest reading of the month, 54°, was on 6/2, the coolest day of the month based on mean temperature was on 6/13, with a high/low of 65/55 (eleven degrees below average).  This was the coolest mean temperature in more than four weeks.

Junes With No 90-Degree Days

As meteorological summer gets underway (June 1 thru Aug. 31) a typical June will see two or three days with highs in the 90s.  However, about once every five years no readings this hot occur; since 1869 there have been 31 years in which this has happened, most recently in 2016 (and at the other end of the spectrum, one June in four has five or more 90-degree days, the most recent being in 2012). 

 

 

Using 90° as the cut-off for hot conditions, rather than 88° or 89°, is a bit arbitrary (and doesn't take into account humidity levels).  Nonetheless, a June with no readings of 90+ is usually results in a cooler than average June.  For example, none of the ten coolest Junes had any high temperatures in the 90s.  Additionally, the five coolest summers started out with a June with no 90-degree readings.  But not every June with no readings in the 90s is so cool.  In fact, the warmest June with no 90s was in 2014.  It was 1.1 degree warmer than average and ranks 39th warmest (out of 150).  And, surprisingly, one of the ten hottest summers, 2016's, started out with a 90s-free June.  Here are some other tidbits:

 

• The most years in a row to have a June without a 90-degree reading is three (1926-1928).  Interestingly, this streak was bracketed by Junes with five or more 90-degree highs (1923 had eight, 1925 had nine, and 1929 and 1930 each had five).  The most consecutive years in which June had at least one day in the 90s is 12 (1997-2008).

• Despite having no days in the 90s in June four years had an above average number of 90-degree days: 1955 (25); 1977 (23); 2016 (22) and 1979 (19).  The average number of 90-degree days in years that had no 90-degree readings in June has been 10 (an average year, since 1930, has had 18; before that the average was just 11).

• 11 of the 31 years with no June 90s had 90-degree readings prior to June 1, with 1977 having the most such days, three.

• 89° was the hottest reading in 12 of the years in which June had no readings in the 90s.  Three of those years had their 89° reading on 6/30 (this excludes any June that had a high of 89° on 6/30 but on other dates in June as well).  One June had it occur on 6/1, another on 6/2.  And three years had their first 90-degree reading on 7/1.

• The coolest warmest reading in June is 81°, occurring in 1903 (the coolest June on record).

 

 

• June 2016 and 1955 had the most readings between 85°-89°, ten.

• Finally, daily low temperatures in the 70s are sometimes considered the counterpart of highs in the 90s.  Interestingly, 22 of the 31 Junes with no 90s had lows in the 70s (nine had some lows of 72° or warmer).  Seven of these Junes had three or more, with June 1869 having the most, seven.  The warmest low during a June with no 90s was 76° in 2014.
