Today in New York Weather History: 4th of July Weather Highlights



Along with hot dogs and fireworks, July 4th is also equated with hot weather, and since 1970 the temperature has risen into the nineties ten times, or about once every five years (most recently in 2019).  Back-to-back years with 90-degree readings on the holiday have occurred three times, the most recent being in 2002 and 2003.  And there was a three-year streak in 1898-1900.  1949 is the only year to see a high in triple digits.  Rain has fallen about once every three years (again, since 1970), but just two of those years, 1978 and 1981, were washouts.  In 2014 the weather was somewhat affected by Hurricane Arthur.



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


Today's high was 91°, and was the third year in a row with a high in the 90s - the longest such streak on the holiday.


This was the fourth year in a row with highs in the 70s on the holiday - the longest such stretch of below-80 readings.


Today had the first 90-degree reading of the year, the third year in a row the first 90 was in July (in 1927 it happened on the thirteenth, the year before that it fell on the ninth).  Typically, the first 90+ (between 1870-1925) occurred around June 14.  Today's high was 90°.


Just two days after a torrid high/low of 98°/78°, today was rainy, foggy and cool, with a high/low of just 64°/62° (the high was 18 degrees below average).  The 0.78" of light rain that fell (between 2 AM and  7 PM) made this the rainiest day of the month.  Today's high would be July 4th's coolest until 1978.


The 1940s started with July 4th's coolest high temperature, and ended with the hottest as today's high soared to 102°.


As hot as it was, today's high of 98° was somewhat of a cool-down from yesterday's 103° and July 2's 100°.  This was also the fifth day in a row with clear skies. 


Showers moved in during the early evening and put a damper on fireworks exhibitions as 0.18" fell between 8-10 PM.  Then the skies really opened up between 11 and midnight, with an additional 0.90" pouring down (actually, this rainstorm occurred between midnight and 1AM on 7/5, but the National Weather Service uses Standard Time year-round and doesn't recognize Daylight Saving Time).


Today was the hottest day of the year, with a high/low of 95°/78° under sunny skies.  And although three other days this summer had highs of 95°, today's low was the warmest, giving this day the highest mean temperature.


New York's Bicentennial celebration (which included the parade of 'Tall Ships' in New York Harbor) took place under partly skies, with temperatures a bit cooler than average (high of 82°/low of 63°).  A brief thunderstorm put a slight damper on festivities during mid-afternoon, but it produced very little rainfall (0.01").




It was a truly miserable holiday as rain fell all morning (totaling 1.19").  Because of clouds and a northeasterly breeze, the high temperature reached only 62° - twenty-two degrees cooler than average.


This was the rainiest 4th of July on record.  Rain began at around noon and continued for much of the day, totaling 1.76".  (But no rain fell during prime fireworks time.)  The first four days of the month had rain, which amounted to nearly three inches.  After this rainy stretch, the next two weeks would be hot and dry, with ten days in the 90s.   


After a sultry morning low of 78°, today's high soared to 95°.  On this broiling hot afternoon, Yankees pitcher Dave Righetti pitched a no-hitter against the arch-rival Red Sox at Yankee Stadium.  




Although hot weather and July 4th seem synonymous, the day began at a chilly 55°, twelve degrees below average and the coolest 4th of July reading on record.  (Two days later the high would reach 98°.)


Just two days after a cool high of 69°, today's high reached 95°, the first of twenty 90-degree days in July.  Despite the heat I spent the evening in Central Park with my brother and his family to listen to the New York Philharmonic's 4th of July concert.




With a high of 96°, this was the hottest 4th of July in 33 years.  Not only was it hot, but unbearably humid as the dew point in the afternoon was in the low 70s, which produced a heat index of 110°.  Today was the first of eighteen 90-degree days in July (eleven of which were 95°+). 


Although four other 4th of Julys had high temperatures that were hotter (in 1966, 1955, 1949 and 1911), today's mean temperature of 88.5° (based on a high/low of 96°/81°) was the hottest of any 7/4.


In the sixteen days between June 19 and today, morning lows fell in the narrow range of 63° to 66°, two degrees cooler than average.  


Today's high of 96° tied 2002 and 1999 as the hottest July 4th since I moved to NYC in 1979.  It was also the first of sixteen 90-degree days this month, which occurred in a 24-day period between July 4-27.




Mostly sunny, hot, and oh-so-humid.  The high temperature reached 92° but it felt like 98°.  Thunderstorms were all around NYC in the evening, but none hit Manhattan.


Skies were gray, and light showers fell through mid-afternoon, the result of New York being on the northwestern fringe of Hurricane Arthur's rain shield.  It was also on the windy side.  However, by late afternoon the sun began breaking through and skies were mostly clear by the time Macy's fireworks exhibition went off.  Although the amount of rain was light, just 0.14", it was the most rain to fall on the 4th of July in six years.  And the high of 74° was the coolest in seven years (and 12 degrees cooler than this year's Memorial Day).    


Skies were overcast through mid-afternoon (including some light rain from 1:30-2:30), but then the sun broke through and the rest of the day was very pleasant, but the high only reached 75°.  This was the second year in a row in which the weather on Memorial Day was much nicer.


It was seasonably warm, and skies were partly cloudy until after 5:00 when clouds moved in, then light showers began around 8:00.  However, despite the rain, Macy's fireworks extravaganza went on as planned as steadier rain held off until after 10:00 when close to an inch fell through 4:00 AM on 7/5.   (The 0.49" that fell before midnight was the most to fall on 7/4 since 1981.)

Today's high reached 90°, the first time in the 90s on 7/4 in seven years.  Skies were mostly clear, but the heat wasn't stifling as humidity levels were bearable during the afternoon hours.


This morning’s refreshing low of 60° (shortly after midnight) was the coolest on the holiday since 1992 (when it was also 60°).  Only ten other 4th of Julys have had a cooler low.  (In the years since 2000 the average low had been 70°.)  The high of 79° was the coolest in six years, but after last week's four-day heat wave, today’s temperatures were delightful for spending time outdoors celebrating the nation’s birthday.   


















Today in New York Weather History: June 25



Tropical conditions through mid-afternoon made the high of 88° feel like the mid-90s.  Today was my brother's wedding out in northern New Jersey, and I was his best man, so wearing a tux in this weather was a bit uncomfortable to say the least.  And the bridesmaids arrived at the church somewhat wilted because the air conditioning in their limo didn't work.  Happily, drier air moved in just as the outdoor reception was getting underway.




The 0.08" of rain that fell in the wee hours of the morning was the first measurable rain on this date in 11 years.


The year's first reading in the 90s was today, four days later than last year's, and the latest date of this occurrence since 1985 (the typical date is in late May).  There would be just seven more days in the 90s this year (the typical number is 18).


0.95" of rain fell during thundershowers between 6-11 PM.  Rain was heaviest at the onset, when 0.53" fell in the initial hour.  


Two rounds of severe thunderstorms moved through the area, one during morning rush hour and the other during the evening commute.  This was much like three days earlier when strong storms rumbled through during mid-afternoon and early evening.  However, in all cases Manhattan was in a protective bubble as the storms either lost their punch, or moved to the north or south.  While three to six inches of rain was common in the suburbs of New Jersey, Westchester County and Long Island, just 0.50" was measured in Central Park.     




Today's high reached 83° for the fifth day of the past six.  (And since 2000, 83° happens to be the most frequently occurring high temperature).


Shortly after daybreak a deluge dumped 0.86" of rain in a little less than an hour.  This tied 6/2 as the rainiest day this month.  And although the rest of the day was rain-free, it was very humid, with dew points in the low 70s during much of the afternoon (this was the first day this year I turned on my AC).  Additionally, today had the first low in the 70s of the year, about three weeks later than average, and the latest date in ten years.
