Today in New York Weather History: Labor Day Weekend (1970 - 2022)

 

Labor_day

 

On average, Labor Day weekend is about five degrees warmer than Memorial Day (high of around 80° vs. 75°).  However, hot temperatures on Labor Day itself aren't overly common.  Since 1970 the afternoon high has topped 90° just five times (most recently in 2015 and 2018).  In terms of inclement weather, chances are 2 in 5 that the entire weekend will be dry, better odds than Memorial Day weekend's 1 in 3 chance.  Tropical systems have brushed the area twice (Edouard in 1996, Ernesto in 2006).  What follows is a recap of 20 holiday weekends that had weather conditions worthy of note.

 

  • 1973 (Sept. 1-3) - This Labor Day weekend has the distinction of being the hottest of the 1970-2022 period - and the only one in which each day's high was in the 90s (95°-94°-96°).  Overall, temperatures averaged thirteen degrees above average.  Saturday's heat had a tropical component to it, which fueled late-afternoon thunderstorms that amounted to 0.25".

  • 1980 (Aug. 30-Sept. 1) - This was the second hottest Labor Day weekend of the period as highs reached: 86°-90°-95°.  After a stifling low of 76° on the morning of Labor Day, the high topped out at 95°, the hottest reading for the holiday since 1973, when it was 96°.   
  • 1983 (Sept. 3-5) - Monday's high was 91°, the last Labor Day to get into the 90s until 2015 (highs in 1996 and 1998 reached 89°). 
  • 1984 (Sept. 1-3) - The weather was good all weekend until the evening of Labor Day when 1.20" of rain poured down during a thunderstorm after 8 PM.
  • 1986 (Aug. 30-Sept. 1) - Saturday's low of 51° is the chilliest reading of any day during Labor Day weekends of the 1970-2019 period.  The entire weekend was cool, with temperatures averaging eight degrees below normal.

  • 1991 (Aug. 31-Sept. 2) - Monday's morning low of 53° tied 1976 and 1883 as the chilliest reading on Labor Day.  
  • 1994 (Sept. 3-5) - This was one of the coolest Labor Day weekends on record, with temperatures seven degrees below average.  It is also one of two Labor Day weekends between 1980-2019 in which each day's morning low was in the 50s (the other was in 1986).    
  • 1996 (Aug. 31-Sept. 2) - There was cause for concern on Saturday of Labor Day weekend when Hurricane Edouard was predicted to make landfall on Long Island.  However, the storm stayed away and the only effect from the hurricane was heavy surf, especially out in the Hamptons.  Although Sunday's conditions were somewhat overcast, Saturday and Labor Day were spectacular (Monday's high reached 89°).
  • 1998 (Sept. 5-7) - The long holiday weekend ended with severe thunderstorms on Monday afternoon and again later that night.  2.07" of rain was measured, making this the second rainiest Labor Day on record, topped only by 1926, when 2.24" fell. 

 

Clipart_severe_thstorm 

 

  • 2000 (Sept. 2-4) - Each day of the extended holiday had above average temperatures as well as a thunderstorm.  In total, these storms produced nearly two inches of rain.  In the 1980-2022 measurement period this is the only Labor Day weekend to have rain fall on each day.
  • 2002 (Aug. 31-Sept. 2) - With an average high of just 68° degrees (11 degrees below average) this is the coolest Labor Day weekend between 1970-2019.  And Labor Day itself was a washout, with 1.63" of rain falling.
  • 2003 (Aug. 30-Sept. 1) - For the second year in a row the temperature never got out of the 60s on Labor Day.  And like the previous year it rained, but not nearly as much fell (0.59"). 
  • 2006 (Sept. 2-4) - The extended weekend started off cool and wet as tropical storm Ernesto moved through, dropping 1.24" of rain; the day's high was just 66°, thirteen degrees below average.  Sunday and Monday, however, were very nice, but cooler than average (mid-70s). 
  • 2011 (Sept. 3-5) - This was the eighth year in a row in which no rain fell on Labor Day, the longest such streak since one of ten years between 1958-1967.  This was also the mildest three-day weekend since 1983, five degrees warmer than average.

  • 2012 (Sept 1-3) - After a sunny and hot Saturday (the high of 91° was the first 90-degree reading during Labor Day weekend since 1998), Sunday and Monday were overcast - but Labor Day's dry streak continued.  The three-day weekend's mean temperature was six degrees warmer than average, the most above average LD since 1983.      
  • 2013 (Aug 31-Sept 2) - Conditions all weekend were sultry with hazy sunshine and uncomfortable levels of humidity.  Scattered thunderstorms occurred throughout the area on every day, but Manhattan was spared until Monday afternoon when rain fell for a few hours - the first rain to fall on Labor Day in ten years.  The overnight hours were especially warm, with AM lows of 73°-75°-74° averaging nine degrees above average.  However, the diurnal variation was just ten degrees. 
  • 2014 (Aug. 30-Sept 1) - This was the warmest Labor Day weekend since 1983 (and fourth warmest since 1970).  The weekend started out mostly overcast with seasonable temperatures (high/low of 80°/65°) but hot and humid air moved in overnight and Sunday and Monday saw highs/lows of 90°/73° and 88°/75°.  On Sunday a half-hour downpour late in the afternoon dumped 0.62" of rain.
  • 2015 (Sept. 5-7) - Sunny and warm throughout with each day warmer than the next (highs of 83°-87°-92°).  Labor Day's high was the first in the 90s since 1983.
  • 2016 (Sept. 3-5) - It was a rain-free weekend, with highs of 75° on Saturday, 80° on Sunday and 84° on Labor Day - which was the same high as 4th of July (and Memorial Day wasn't far behind, with a high of 82°).  It was a nice surprise that the holiday weekend ended up being so nice since earlier forecasts predicted tropical storm Hermine would stall off the Mid-Atlantic on Sunday and Monday, but it moved further east and posed no threat.  
  • 2017 (Sept. 2-4) - After a cool and mostly overcast Saturday and Sunday (which included 1.27" of rain on Saturday evening thru early Sunday AM), Labor Day turned out beautiful, with mostly clear skies and seasonable temperatures.  All told, this was the coolest Labor Day weekend since 2004).
  • 2018 (Sept. 1-3) - After close to seasonable temperatures on Saturday and Sunday, Labor Day featured summertime heat, with a high/low of 90°/75°.
  • 2020 (Sept. 5-7) - Cookie cutter conditions prevailed as each day of the extended weekend was sunny, with comfortable humidity and temperatures that were slightly above average (+2 degrees).  Each day had very similar highs/lows: 80°/65° (Saturday), 82°/66° (Sunday), and 79°/66° (Labor Day).
  • 2022 (Sept. 3-5) - After a seasonably warm Saturday, Sunday and Monday heated up, with highs/lows of 90°/71° and 88°/73°.  The weekend was dry (and sunny/partly cloudy for the most part) until after dark on Labor Day when a few showers produced 0.06".  All told, the weekend was six degrees warmer than average (high/low of 87°/70°).

Warm September Mornings in New York

 

Clipart_suntapping_onwindow

 

Average low temperatures in New York during September range between 64° at the start of the month to 56° by the 30th, but a typical September will see three days with daily lows of 70° or milder (the average in the years since 2010 has risen to five).  Since 1869, the September with the most days with lows in the 70s is September 1961 - twelve.  At the other end of the spectrum there have been 33 years with no 70-degree lows (about once every four or five years), with the most recent being in 2009.  What follows are additional facts about warm September mornings:

 

  • After 1961's twelve days with lows in the 70s, 1971 follows with eleven and 1959 reported ten such days.  September 1884 had the most consecutive days with lows in the 70s, eight, which occurred between Sept. 4-11.  More recently, September 1979 had a streak of seven days in a row.  The greatest number of 70-degree lows in consecutive years occurred in from 1905 to 1907 when there were eight, seven and nine, respectively.
  • The warmest daily minimum in September is 79°, which happened twice, first on Sept. 7, 1881 and a second time on Sept. 2, 1898.  Lows of 78° have occurred five times: on Sept. 3 and 4 in 1898; Sept. 11, 1983; Sept. 6, 1985; and most recently on Sept. 2, 2010. 
  • The coolest low temperature to be the mildest of any September is 64°, which occurred in 1917 and 1935.
  • There has been one three-year period with no 70-degree lows in September, 1962 to 1964.  The longest streak of Septembers with lows in the 70s lasted twenty-three years between 1894 and 1916.  We're currently in the midst of an eleven-year streak (2010-2020), with every September except for 2019 and 2020 having four or more lows in the 70s.
  • Although only six of the days had 70-degree lows, September 2018 established a new record with 17 days with lows of 67° degrees or warmer (the average number of such days is six).

Looking Back at New York Weather: September 30

 

1871 (Saturday)

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

 

1884 (Tuesday)

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

 

1913 (Tuesday)

Today was the 15th day this month with a high cooler than 70°, the most of any September in the years since 1890.  Before 1890, five years had this many, or more (Sept. 1871 and 1876 had 17 such days.)

 

1921 (Friday)

This September stands out for being the only one that was warmer than August.  In keeping with the warm conditions, today's high was 87°, then a severe thunderstorm between 5-6 PM dumped a little more than an inch of rain, along with winds that gusted to 40 mph. 

 

1948 (Thursday)

Until today, when 0.70" of rain fell, just 0.53" of rain had fallen during the month.  Today's amount was more than what fell in the previous six weeks. 

 

1959 (Wednesday)

The unseasonably warm temperatures of August (at the time, the fifth hottest on record) continued in September, which tied September 1931 as the second warmest (it's now tied for fifth).  The month's temperatures were divided into three ten-day periods.  The first ten days were eight degrees above average, the middle ten were six below average, and the last ten days were nine above average.  Today, with a high of 82°/70°, was twelve degrees above average; the low was what the average high typically is.

1963 (Monday)

Today's high of 65° was the 14th cooler than 70° this month, the most in September since 1913 (which had 15).  However, this September had 13 days with highs of 65° or cooler, while Sept. 1913 had only three. 

 

1983 (Friday)

Rain from the remnants of tropical storm Dean moved through during the early morning.  2.64" fell between 4-9 AM, but the bulk of it poured down in the hour between 7:30-8:30, when 2.05" was measured.  Today's rainfall was comparable to the amount that fell between Sept. 1-29.

 

1986 (Tuesday)

Today's summer-like high of 89° was 20 degrees above average, and a record for the date.

1992 (Wednesday)

For the second year in a row, the chilliest reading of September occurred on the final day of the month, and in both years the reading was 44° (12 degrees below average).  However, this year's high, 58°, was five degrees chillier.

 

2001 (Sunday)

Today's high of 55° was 15 degrees chillier than average.  It was also the last time until September 2016 that a day in September had a high only in the 50s.

 

2005 (Friday)

Today's high/low of 67°/50° made this the only day of the month that a had cooler than average mean temperature (four degrees below the norm).  Not only was this the second mildest September on record (now tied for third), but the fourth driest (0.48" was measured).

2010 (Thursday)

0.75" of rain fell in a 45-minute period just before daybreak (6-6:45 AM).  Overall, 1.10" fell during the morning.  This followed a rainstorm on 9/27-28 that dropped 1.66".  These two rain events accounted for 75% of September's rainfall.

 

2016 (Friday)

It was a gray day, with persistent drizzle and winds out of the northeast.  These conditions kept the temperature in the upper 50s all day.  The high of 59° (eleven degrees below average) was the first high in the 50s in September in fifteen years.

Today in New York City Weather History: September 29

 

1974 (Sunday)

In its fifth year, this was the first New York City Marathon to see rain as thundershowers produced 0.32" of rain between 3-4 PM and 0.10" between 5-6 PM (but well after the leading runners had crossed the finish line).  It was also a warm day, with a start-time temperature of 74°.

1979 (Saturday)

The morning low was a summer-like 71°, fifteen degrees above average.  This was the latest date for a low in the 70s since 1959 (when it occurred on 10/1), and would be the latest date until 2005, when that year's last 70-degree low temperature fell on 10/7 (and then 2010's would occur on 9/28; 2015's on 9/29; 2017 would report 70-degree lows on 10/8 and 10/9; and in 2018 it would happen on 10/10.)  The average date for the occurrence is Sept. 11.

 

1996 (Sunday)

The 0.18" of rain the fell between 2-5 AM was the first rain on this date in seventeen years.

 

2000 (Friday)

The morning low of 43° was the chilliest reading in September since 1974 (when it occurred on 9/24).

2023 (Friday)

Three days after rains associated with tropical storm Ophelia moved out, a much bigger rain producer flooded the City today (creating a flood emergency).  Starting last night, 5.38" poured down today (9th greatest daily rainfall), much of it falling between 8-11 AM. While Ophelia dropped three inches over the course of four days, today’s storm dropped that amount in just two hours (and nearly four inches in three hours).

This storm brought September’s rainfall to 14.21", making it the second wettest September on record and the fourth rainiest of any month (and an additional 0.04" would fall tomorrow).  Before today’s rain September was already a very wet month (among the 15 wettest Septembers) but today's deluge catapulted it to second wettest September.  While it was raining the temperature was stuck in the low 60s.

Today in New York Weather History: September 28

 

Since 1970, Sept. 28 is the average date of the last reading in the 80s (or warmer) of the year.  It's occurred as early as Sept. 2 (in 1902) and as late as Nov. 15 (in 1993).  This occurs one month after the average date of the last reading of 90°+ (Aug. 28).

 

1975 (Sunday)

The sixth NYC Marathon was held today and participants breathed a sigh of relief as the City dried out from a string of rainy days that produced 8.95" over the previous nine days.  This included an unprecedented four days in row in which more than an inch of rain fell.  Today, however, was sunny with near seasonable temperatures (high/low of 69°/57°). 

 

1977 (Wednesday)

This was the seventh day in a row in which some rain fell.  Today's amount was just 0.03", which fell between 3-4 AM.  (The first day of this streak also had 0.03".)  In total, three inches of rain fell during the seven days. 

 

1984 (Friday)

The month's temperature extremes occurred three days apart as this morning's low of 44° followed a high of 86° on 9/25.

 

2004 (Tuesday)

Three weeks after the remnants of Frances soaked the City, and ten days after Ivan, the remnants of a third tropical system, Hurricane Jeanne, moved through.  By the time its rain ended the following morning, 4.66" had fallen, the most from a storm since tropical storm Floyd dumped 5.44" in 1999.  The rain that fell today, 3.84", was a record for the date and brought the month's total to 11.41", making this the rainiest September since 1934.

2010 (Tuesday)

After a sultry morning low of 70° (fourteen degrees above average), the temperature rose only three more degrees the rest of the day.  This was the 55th, and last, day this year with a low of 70°+, which was 50% above average and the third greatest number of days on record (now tied for fifth place).

2011 (Wednesday)

For the past seven days the morning lows were between 68° and 70°, twelve degrees above average, and more typical of mid-August.  High temperatures during these days averaged 77°, five degrees above average.

 

2012 (Friday)

Torrential downpours through mid-afternoon amounted to 1.96", much of which fell in a two-hour period between 9:20-11:20 AM.  This was the second day this month with more than an inch of rain (1.54" fell on 9/18), and the first month with two such rain events of this magnitude since last October.  Additionally, this was the seventh year in a row, and tenth of the past eleven, in which rain fell on this date.

2014 (Sunday)

The last weekend of the month had spectacular weather.  Under clear skies on Saturday and sunny skies on Sunday, high temperatures rose into the low 80s, thirteen degrees above average.  (And Friday was equally fine, with clear skies and a high in the upper 70s.)

 

2018 (Friday)

The 0.77" of rain that fell this morning pushed September's total rainfall past six inches, making this the third month in a row with six inches or more.  This became just the ninth such streak on record (going back to 1869), all of which have occurred since 1971.  (An even more impressive monthly rainfall streak would be established on this date in 2021.)

 

Chart - 3 months 6 inches+ precip

 

2021 (Tuesday)

Early afternoon showers amounted to 0.27”, pushing September’s rainfall over ten inches (10.03”).  Not only was this the most rain to fall in September since 2004, it was the third month in a row with more than ten inches of rain  – the first time for such a streak (July had 11.09”, August had 10.32”).  However, this wasn’t Central Park’s rainiest three-month period, as the 31.44” that fell was three inches less than the 34.43” that fell in Aug-Sept-Oct 2011 (18.95”, 9.39” and 6.09”, respectively).

This was the 21st day in a row with no rain.  (Three of the other nine days of the month had rain, which amounted to 1.91".)

 

1975 (Saturday)

Although it amounted to just 0.02", the rain that fell shortly before daybreak made this the ninth day in a row in which measurable rain fell.  (The first day of this streak also received 0.02").  In total, 8.95" of rain fell, most of it coming during four days in a row (Sept. 23-26) that each had more than an inch of rain. 

 

1985 (Friday)

Hurricane Gloria made landfall on Long Island near the Nassau/Suffolk border, and dumped heavy rain in the City during the morning (3.13", a record for the date), with most falling between 9:30 AM-12:30 PM.  Skies cleared around 1:00 and the rest of the afternoon was beautiful.  The bountiful rain helped put a dent in the year's rainfall deficit.  (To read my first-person account of the storm double click here.)

1940 (Thursday)

Clear skies and very chilly, with a high/low of 60°/42°, which made it feel more like early November.  The morning low, 15 degrees below average, was a record for the date (which still stands).  This chilly air followed a rainstorm that swept through yesterday morning, dumping 2.36" of rain (a record for the date that also still stands).  This accounted for almost all of September's 2.82" of rainfall. 

 

1970 (Saturday)

Between Sept. 22 and today, four of the days had afternoon highs in the 90s: 94°-93°-87°-90°-91° (today).  Furthermore, all five days had mean temperatures that were fifteen degrees or more warmer than average.  Yesterday and today's highs were records for the dates; today's was the latest reading in the 90s since 1941 (and it would be the latest until 2019 when there was a high of 93° on 10/2). 

 

1975 (Friday)

For the fourth day in a row, more than an inch of rain fell.  At the onset of today's deluge rain had fallen for 47 consecutive hours.  Total rain during these four days amounted to 7.43", as 1.82" fell today; 1.05" yesterday; 2.26" on 9/24 and 2.30" on 9/23.

After a high of 89° at 3 PM, the warmest reading of the month (and a record until 1970), the temperature fell steadily (especially after 8 PM) until it bottomed out at 52° by daybreak the next day.

 

1946 (Wednesday)

This was the third day in a row with a low of 66°, and it followed three days in a row with lows of 67°.  This compares to average lows this time of year in the upper 50s.  (High temperatures for these six days, however, were all different.)

 

1975 (Thursday)

Between Aug. 28 and today, only two days had above average mean temperatures.  This four-week period was nearly five degrees cooler than normal.  Today was seven degrees below average, with a high/low of 62°/55°.

 

1980 (Thursday)

Three days after the mercury soared to a sizzling 94°, today's high temperature was a chilly 62°, eleven degrees below average.

 

1991 (Wednesday)

Although 1.97" of rain fell today, conditions were dry during the daylight hours.  Today's rain accounted for more than half of the month's 3.71" total.  It was also the first rain on this date in 11 years.

 

2010 (Saturday)

Today, with a high/low of 89°/67°, and the previous three days, averaged 11 degrees warmer than the norm.  This was also the twelfth day this year with a high of 89°, the most on record.

2018 (Tuesday)

Close to two inches of rain fell today (1.95", to be exact), starting shortly before daybreak and continuing thru early evening.  Nearly half of it poured down in the early afternoon between 1:00 and 2:00.  Today's rain pushed September's rainfall over five inches, making it the sixth month this year with more than five inches of precipitation, joining 1998 as the only two years in which this occurred (between January thru September).

2020 (Friday)

For the past week a strong high pressure system was anchored over the Northeast, bringing fair skies, low humidity, and the coolest temperatures of the month.  It was also responsible for keeping the remnants of two hurricanes (Sally and Beta) south of the area.

 

2022 (Sunday)

After nice conditions during the daylight hours, 1.11" of rain poured down during a thunderstorm late in the day, mostly between 9:30-10:30 PM.  (Ironically, 9/25 is one of the calendar dates least likely to see measurable rain.)  The intensity of the rain was nearly identical to a torrential downpour on 7/16 when 1.10" fell in a 45-minute period during the afternoon.  Meanwhile, amounts were higher west of the City (1.44" at Newark Liberty Airport) and less to the east (0.78" at LaGuardia, 0.28" at JFK).

 

2023 (Monday)

For a third day remnants of tropical storm Ophelia continued spinning in the Atlantic Ocean off the New England coast, bringing mostly a steady drizzle that ended by late in the afternoon.  Today's rain amounted to 0.59", bringing the storm's total to 2.80".  This brought September's rainfall to 8.15", making it the wettest month of the year.

Because of the time of year Yom Kippur falls (mid-September thru mid-October) the weather is relatively undramatic, with few temperature extremes or notable storms to speak of (based on the period 1970-2020).  However, with that said, this post remembers a number of years that had memorable weather conditions on the Day of Atonement. 

 

  • 1972 (Sept. 17-18) - This was the warmest Yom Kippur of the 1970-2022 period as the high on the 17th reached 92° while the 18th saw a high of 86°.    
  • 1979 (Sept. 30 - Oct. 1) - 0.81" of rain fell on 10/1 between 1-9 PM, making this the wettest Yom Kippur in the years since 1970 (until 2005).
  • 1989 (Oct. 8-9) - This was the chilliest observance of Yom Kippur until 2000.  The high on the 8th was 59°, while the high/low on the 9th was only 55°/40°, twelve degrees below average.
  • 1991 (Sept. 17-18) - Falling on the same dates as the hottest Yom Kippur of the period, in 1972, this year's was the second warmest.  It featured the hottest temperature on the first evening of Yom Kippur, 93° (a record for 9/17), which was nineteen degrees above average.  The next day was more comfortable, but still a warmer than average 83°.
  • 2000 (Oct. 8-9) - The morning of the 9th had a low of 38°, sixteen degrees below average and the chilliest reading on Yom Kippur in the 1970-2022 period.  This reading was just one degree shy of tying the record for the date.
  • 2002 (Sept. 15-16) - It was mild and rainy during the first half of the holiday.  Although not all of the rain fell between sunsets, nearly one inch fell between 2 PM on the 15th and 10 AM on the 16th.  The high was 79° on 9/15 and 81° the following day, about five degrees above average.
  • 2005 (Oct. 12-13) - The holiday fell in the midst of a huge rainstorm.  Seven inches of rain fell on the two days, with two inches of it pouring down between sundown on the 12th and sundown on the 13th.  
  • 2014 (Oct. 3-4) - Skies were clear and temperatures seasonable the evening of 10/3, but 10/4 saw 1.18" of rain fall between 10 AM and 5 PM, making it the second rainiest Yom Kippur in the years since 1970.  However, skies cleared rapidly after 5 PM and conditions were as nice as the evening before. 
  • 2017 (Sept. 29-30) - After a streak of sixteen unseasonably warm days in a row (with a high/low of 87°/69°, nine degrees above average), today and tomorrow had seasonable temperatures (under sunny skies), i.e., highs in the upper 60s/lows in the mid-50s.
  • 2018 (Sept. 18-19) - The remnants of Hurricane Florence brought a series of heavy downpours from lunchtime thru late afternoon on the 18th (dropping a little over an inch of rain), but by sundown skies had cleared and the following day was partly cloudy, with above average temperatures (high/low of 81°/68°).
  • 2019 (Oct. 8-9) - After a dry and cool evening on the 8th, the 9th became raw, rainy and breezy after sunrise as a coastal storm brought a little more than a half inch of rain, mostly between 10 AM-2 PM.  This was the largest daily rainfall in the past seven weeks. Temperatures stayed in the 50s all day (high/low of 59°/51°, four degrees below average).
  • 2020 (Sept. 27-28) - The longest stretch of days with no measurable rain since the fall of 2017, sixteen, ended just before midnight on the 27th when a light shower produced 0.03" of rain.   Both days had temperatures that were well above average, with highs/lows of 79°/67° and 77°/69°, respectively.
  • 2022 (Oct. 4-5) - It was showery and cool with temperatures stuck in the 50s for the entirety of the holiday (sundown to sundown); showers produced half an inch of rain (in 2019 Yom Kippur had temperatures and rainfall that were very similar).  These inclement conditions were from the remnants of hurricane Ivan, which first affected the area on the first of the month.  Skies cleared shortly after the holiday ended.
