Today in New York Weather History: June 4

 

1895

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

1970

After a summery first three days of the month with highs in the upper 80s, today was gray and raw with temperatures stuck in the 60s, and periods of light rain between 11 AM and 3 PM.  The 0.15" of rain measured in Central Park was the first rain to fall on this date in fifteen years.

1972

Although occurring very early in the month, today's high of 86° would be the warmest reading of the entire month.  By coincidence, 86° was also the warmest temperature in April and May.

1983

For the fourth day in a row, the high temperature was 75°, which was very close to the average high. 

75

1989

This was the beginning of a two-week stretch in which rain fell on ten of the days.  Last year, a similar rainy spell occurred in the second half of July.  This year, 7.28" of rain was measured, while 7.44" fell during last year's soggy fortnight.  Today's rainfall was a minimal 0.09", which fell shortly before daybreak.

2003

2.75" of rain fell, a record for the date.  Shortly before the rain ended, 0.66" fell in the hour between 9-10 PM.  The high temperature was just 57°, nineteen degrees below average.

2007

After beginning the night before, nearly four inches of rain was dumped on the City as the remnants of tropical storm Barry moved through.  The rain was over by noon.  The amount that fell from the storm was double the amount that fell during the entire month of May.

 

Umbrellas

2009

Rain that began late last night continued until daybreak today, amounting to 0.87" (0.54" fell this morning).  This was the fifth year in a row that rain fell on this date.

2012

It was a mostly gray and damp Monday, with a high of just 63° - comparable to the average low of the past two weeks.

Today in New York Weather History: October 29

 

1929 

Wall Street's "Black Tuesday", which presaged the Great Depression, was partly cloudy and chilly with a high/low of 49°/37°, about ten degrees below average.

 

Blacktuesday1929

1971

One day after a high of 77°, today's reached 78°, a record for the date (and 19 degrees above average).  This was the mildest reading since Sept. 16. 

1973

A heavy, all-day rain amounted to 3.67", a record for the date.  Up until today just 0.03" had fallen in October (and it fell twenty-seven days earlier).

1989

Today and the past three days had unseasonably warm high temperatures that were very similar: 77°-76°-77°-76° (today).

2000

Although it was just 0.01", the rain that fell today was the first on this date since 1984 (when just 0.02" fell).

2003

Until yesterday it had been a dry month, with just 1.26" of rainfall measured.  Then 3.62" fell in the past three days, including 1.63" that fell today.

2011

An intense nor'easter lashed the area with high winds and outrageously early snowfall.  The 2.9" of heavy, wet snow that was measured in Central Park was the most ever to fall in October (5.2" fell in Newark and over a foot buried northern NJ, parts of the Hudson valley, Connecticut, western Massachusetts and New Hampshire).  Since the temperature never fell below freezing, there was mostly just slushy accumulation on City streets.  However, the day's low of 33°, which occurred in the early afternoon, was the coldest reading in October since 1988.  Total liquid precipitation from the storm was two inches.  Remarkably, the next measurable snow wouldn't be for another twelve weeks (when 4.3" fell on Jan. 21, 2012).

2012

Unbelievably, an even more devastating storm than last year's nor'easter - hurricane/nor'easter Sandy - struck between noon and midnight.  And it more than lived up to its hype.  Although rain wasn't the issue (less than an inch fell), its 60-80 mph wind gusts and record storm surge wreaked havoc on New York's transportation system and power grid.  Not only did the storm surge strike at high tide, but also during a full moon, resulting in flooding never before experienced in Manhattan.  

 

Sandys_fury

2017

On the five-year anniversary of superstorm Sandy, an intense nor'easter lashed the area with gusty winds and an all-day rain that amounted to 3.03".  This was more rain than fell in the past 60 days, and the biggest rainstorm of the year, passing the rainstorm of 5/2 by 0.01".   

2020

The remnants of hurricane Zeta (which struck the Gulf Coast last night) combined with the energy from a winter storm that struck the southern Rockies and Plains earlier in the week, resulting in rainy and raw conditions in the Mid-Atlantic states.  Rain began here around 7 AM and continued until mid-day on the 30th.  1.53" fell today, 0.64" the next morning.  The rain fell heaviest from 10 AM until 3 PM today, with nearly an inch measured.  After the rain became lighter gusty winds of 25-30 mph moved in.

Today in New York Weather History: October 28

 

1919

Today's high of 83° was a record, and 24 degrees warmer than average.  However, a strong cold front moved through later in the day, dropping the temperature to 48° shortly before midnight (which was the average low for the date).

1947

Today was the tenth day since 10/14 with a high of 77° or warmer.  (Typical highs during the second half of October are in the 60°-64° range.)  Not only was it unseasonably warm but dry as just 0.01" of rain fell during this fifteen-day period.  Not surprisingly, this would become the mildest October on record (later tied in 2007) - which, ironically, began with a record low.   

1963

Today's 0.10" rainfall (during the morning and afternoon) made this the rainiest day of the month, a month that would be the second driest on record (behind June 1949, which had 0.02").  Only one other day this month had rain and it was more than three weeks ago, when 0.04" fell on Oct. 3.  

1973

Today was the 26th day in a row with no measurable precipitation, the longest dry spell since before 1960 - and it wouldn't be topped until June 1999.  Furthermore, from Sept. 15 thru today, a total 44 days, just 0.91" of rain fell.  Not only was this the longest streak with less than an inch of rainfall since a 45-day streak in Jan/Feb 1968, it exceeded by two days a streak of 42 days that ended on Sept. 13 of this year.  

1976

For the second morning in a row the low was 29°.  Today's low was a record.  This was also the end of a 12-day period in which temperatures averaged 10 degrees below average.  This streak was instrumental in making this October the coldest since 1925. 

1984

On the day of the NYC Marathon, the City basked in a balmy 79° degrees, the warmest reading of the month.  (In a case of flip-flop, the month's chilliest reading occurred at the beginning of the month.)  Later tonight heavy rain fell between 11 PM and 1AM, with 0.28" of rain fell during a five-minute downpour (11:45-11:50 PM) and 0.88" overall.

 

Joggers_centralpark 

1986

It was a gloriously sunny and and mild day (high of 68°), perfect for the ticker tape parade in lower Manhattan celebrating the Mets World Series championship the over the Red Sox.  The sunny skies were particularly welcome after being preceded by three damp and gloomy days.

 

Mets 1986 world series victory parade

1989

Today's high of 77° tied 10/26 as the warmest temperature of the month.  This was also the sixth day in a row with highs in the 70s.

1995

1.21" of rain fell in the morning, the fourth rainfall this month that exceeded one inch.  Each storm occurred about a week apart and produced a total of 7.13".  0.86" of today's rain poured down between 5-6 AM.

2006

A nor'easter that moved in last night dumped 2.54" by the time it exited around 2:00 this afternoon.  Shortly before the last raindrops fell a final rain band dumped 0.33" in a five-minute period between 1:32-1:37 PM.

 

Noreaster42008

Two inches of rain fell, with the greatest amount (0.87") falling between 10 AM-noon.  Besides the rain it was also unseasonably chilly, with a high of only 47° and a low of 39°. 

2009

1.29" of rain fell thru mid-afternoon, making this the third year of the past four to receive more than an inch of rain on this date.

2012

The entire Mid-Atlantic region was feverishly preparing for the worst as hurricane Sandy approached.  For the second time in 14 months New York City's entire transit system was shut down (the first time was for hurricane Irene).  To add insult to injury, today was the sixth day in a row with overcast skies.        

 

Sandy

2015

Showers and downpours that fell throughout the day amounted to 1.40".  Today's rain accompanied a warm front that pushed temperatures into the upper 60s by nightfall (the day's high was 69°, at around midnight).  More than an inch of rain also fell in the three previous years rain fell on this date (in 2009, 2008 and 2006).

Hurricanes & Tropical Storms That Have Lashed New York City Since 1970

Hurricane

 

Since 1970 (thru 2021), more than thirty hurricanes and tropical storms have made their presence known in the New York City area, with the most serious being Gloria in 1985, Floyd in 1999, Irene in 2011,  Sandy in 2012, and Ida in 2021.  And 2004 was noteworthy for having three tropical storms that flooded New York in the month of September (2020 had three, but over the course of 13-1/2 weeks).  These tropical systems have lashed the area as early as the first week of June and as late as late October, but September is by far the month when the majority have struck.  The longest stretch with no tropical systems visiting the area is five years (1986-1990) 

Although tropical systems often cause flooding and wind damage, nor'easters can wreak as much, if not more, havoc.  When tropical storms reach this far north they are in the process of weakening, while nor'easters are usually gaining strength at this latitude.  To read about some of New York's memorable nor'easters click here.  The hurricanes and tropical storms discussed below are listed in chronological order.  (Please note that three named storms that had no impact on New York are included because they were originally expected to affect us.)

 

DORIA

Rain from tropical storm Doria moved in shortly before daybreak on Aug. 27, 1971, and continued through early evening.  Rain was heaviest between 1:00 and 3:00 PM, when 1.76" poured down.  In total, 4.16" was measured - a record for the date.  Wind gusts of 40-50 mph accompanied the rain.  Then, after a break of about four hours, a second round of rain moved in on Aug. 28 between 1-6 AM.  1.80" fell, with more than half (1.11") falling in the hour between 3-4 AM.  In total, Doria produced 5.96" of rain in Central Park.  Rainfall amounts were even greater in New Jersey and southeastern Pennsylvania.     

HEIDI

On Sept. 14, 1971, less than three weeks after Doria, tropical storm Heidi brought heavy rain to the area.  Between 4-9 AM and 2-4 PM, 3.76" of rain poured down.  Today's amount was 0.06" shy of the record for the date.      

AGNES

Rain and gusty winds from the remnants of what was Hurricane Agnes moved through the area on June 22, 1972, mostly between 7 AM-7 PM.  By the standards of tropical systems, rainfall wasn't particularly heavy as just 1.19" was measured.  This paled in comparison to the catastrophic rains of 8-12 inches that Agnes dumped on parts of New York state and Pennsylvania.  Although the main thrust of the storm was today, wraparound rain would fall tomorrow and on the morning of June 25, delivering an additional 1.39".   

BELLE

Hurricane Belle made landfall as a Category 1 storm near Jones Beach around midnight on Sunday, Aug. 9, 1976.  A little more than four inches of rain fell, much of it between 10 PM and midnight, when 2.37" poured down.  This deluge is memorable for me because it happened on the evening my brother and I drove from Pittsburgh to New York for my first visit to the Big Apple - and we were clueless about the hurricane.  I remember being alarmed by the blinding sheets of rain as we made our way through northern New Jersey.  Fortunately, because the eye was 75-100 miles to the east, we escaped any high winds.    

DAVID

The remnants of tropical storm David moved through between 4 AM and daybreak on Sept. 6, 1979, with 50-mph wind gusts and 1.22" of rain.  When it was a hurricane, David was one of the most powerful on record, the only category 5 storm to strike the Dominican Republic, where it killed thousands.  By the time it made US landfall in Georgia, it was considerably weaker. 

DEAN

Rain from tropical storm Dean moved through during the early morning of  Sept. 30, 1983.  2.64" fell between 3-8 AM, but the bulk of it poured down in the hour between 6:30-7:30, when 2.05" was measured.  Today's rainfall was comparable to the amount that fell between Sept. 1-29. 

GLORIA

Hurricane Gloria made landfall on Long Island near the Nassau/Suffolk county line on Sept. 27, 1985, and dumped heavy rain in NYC during the morning (3.13", a record for the date), with most falling between 8:30-11:30.  The sky 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.) 

HUGO

Powerful category 4 Hurricane Hugo made landfall near Charleston, SC overnight on Sept. 22, 1989, and the New York metro area was prepared for 5-10 inches of rain when the storm's remnants moved up the coast.  However, the region was spared when the storm moved inland instead and stayed well to the west.  This was a big relief since six inches of rain had already fallen between Sept. 14-20.  What the City did experience was warm and humid conditions.

BOB

Hurricane Bob struck the eastern end of Long Island on Aug. 19, 1991, and then struck southeastern New England and Cape Cod.  The impact on New York City was heavy rain, mostly between 3 AM-noon, that amounted to 2.53".

BERTHA

Rain and wind from tropical storm Bertha moved in late on July 12, 1996 (a Friday), and continued until mid-afternoon on July 13.  About two inches of rain fell and was accompanied by winds of 30-45 mph.  Western New Jersey and the lower Hudson River valley had the heaviest rain, picking up between three and seven inches.    

EDOUARD

An early forecast caused concern on the Saturday of Labor Day weekend in 1996 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.

DANNY

On July 24, 1997 the remnants of hurricane Danny dumped 3.75" of rain, the rainiest 24-hour period on record for the month of July in New York.  (Rain that fell after midnight brought the storm's total rainfall to 4.62".)  Rain was heaviest between 8:21-9:21 PM when 0.94" fell.  With winds out of the east/northeast, it was also a very cool day; the high of 68°/low of 58° was fifteen degrees below average. 

FLOYD

Tropical storm Floyd flooded the area with 5.02" inches of rain on Sept. 16, 1999, forcing many businesses to close early and causing service on some subway lines to be suspended because of track flooding.  Today's rainfall, a record for the date, was an inch more than we had for the entire summer.  More than half of it fell between 8 AM and 1 PM, but an additional 0.76" fell from a final band of heavy rain that moved through between 6-7 PM.  Rainfall in Newark and Philadelphia exceeded seven inches.  Floyd produced historic flooding in North Carolina, Virginia, Delaware, eastern Pennsylvania and New Jersey and was one of the ten most destructive natural disasters in US history.    

FRANCES

Heavy rain (3.77") from tropical storm Frances flooded the area on Sept. 8, 2004 shortly before the morning rush hour (most fell between 4-7 AM).  1.76" fell between 5-6 AM.  Frances' effects were felt here three days after it made landfall as a slow-moving category 2 hurricane on Florida's east coast.  

IVAN

2.18" of rain fell during the morning of Sept. 18, 2004, most of it between 8-10 AM, as the remnants of Hurricane Ivan moved through.  Ivan's rainfall was much heavier in Pennsylvania and upstate New York.  Damage -wise, the storm was one of the five costliest hurricanes (until 2010's Hurricane Irene pushed it down to sixth).  

JEANNE

Three weeks after the remnants of Frances, and ten days after Ivan, the remnants of a third tropical storm, Hurricane Jeanne, moved through on Sept. 28, 2004.  By the time its rain ended the following morning, 4.66" had fallen, the most from a storm system 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.  

ERNESTO

Sept. 2, 2006 was the Saturday of Labor Day weekend, and it was 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 a bit cooler than average (mid-70s).  

BARRY

After beginning the night before, nearly four inches of rain was dumped on the City as the remnants of tropical storm Barry moved through on June 4, 2007.  The rain was over by noon.  The amount that fell from the storm was twice as much as fell during the entire month of May. 

HANNA

Tropical storm Hanna dumped 3.54" of rain on Sept. 6, 2008, mostly between 3-9 PM.  Rain was heaviest between 5-6 PM when 0.97" poured down.  As a hurricane, Hanna devastated Haiti and killed more than 500.  It made landfall in the US near Myrtle Beach, SC.  The rainfall Hanna dumped on New York was the biggest 24-hour soaker of the year, and the most in sixteen months.  It was also a record rainfall for the date. 

EARL

Hurricane Earl brought only overcast skies and muggy conditions to the New York area, but it lashed the Eastern end of Long Island on Sept. 3, 2010.  Then, as a downgraded tropical storm, it made a direct hit on Cape Cod.  

IRENE

During the evening of Aug. 27, 2011 wind and rain from Hurricane Irene began lashing the area as it slowly made its way north from the North Carolina and Virginia coasts.  By midnight, 2.88" of rain had fallen, and 3.99" fell the morning of the 28th.  As a precaution, New York's transportation system was shut down at noon and 350,000 residents were evacuated from low-lying areas. 

Irene dumped a total of 6.87" of rain, one of the greatest 24-hour rain totals measured in Central Park.  This tropical deluge brought August's total rainfall to 18.95" - the most to fall in any month.  In addition to the flooding rains, winds gusted between 50-70 mph (a gust of 62-mph was recorded at Central Park), downing more than 2,000 trees along City streets and in parks. 

LEE

A week and a half after Irene, the moisture from tropical storm Lee, combined with a cold front, dropped 5.33" of rain over the three-day period Sept. 6-8, 2011.  Rainfall amounts of up to ten inches flooded Maryland, central and eastern Pennsylvania, and much of the same terrain in New York State flooded by Irene.

SANDY

One year after a pre-Halloween snowstorm crippled the area, superstorm Sandy struck on Oct. 29, 2012 between noon and midnight.  It lived up to its advance hype - and then some.  Although heavy rain wasn't an issue (less than an inch fell), 60-80 mph wind gusts, and a record storm surge wreaked havoc on New York's transportation system and power grid.  The storm surge struck not only at high tide (8:30 PM), but during a full moon, creating flooding that Manhattan had never experienced before.    

ANDREA

A soaking rain fell throughout the day on June 7, 2013 as the remnants of tropical storm Andrea moved up the coast.  Rain came down especially hard after dark.  In total, 4.16" fell, a record for the date - and the second greatest June rainstorm on record (an additional 0.43" fell after midnight on 6/8).  This was the second earliest tropical system to affect New York in the 1970-2020 period; the earliest was tropical storm Barry on June 3-4, 2007.  Because of the rain and cloud cover, today's high only reached 63°, thirteen degrees below average. 

ARTHUR 

Although hurricane Arthur put somewhat of a damper on the 4th of July in 2014, New York was on the northwest fringe as the system raced northeastward from the North Carolina coast.  Through mid-afternoon skies were gray with light showers, but just 0.14" was measured.  (By contrast, severe thunderstorms on the evenings of 7/2 and 7/3 produced 2.74" of rain.)  It was a breezy day, with winds occasionally gusting to 30 mph.  By the time Macy's fireworks exhibition began skies were clear.  However, conditions further east, on Fire Island and in the Hamptons, were worse.    

FLORENCE & GORDON

The remnants of Hurricane Florence, which brought disastrous flooding to southeastern North Carolina a few days earlier, synched-up with a cold front and brought heavy rain during the afternoon of Sept. 18, 2018, producing 1.16".  When the rain began the dew point was at a sticky 74°.  This rain came eight days after the remnants from Hurricane Gordon brought 1.38" of rain (but it fell over the course of nearly 24 hours). 

BARRY

This was the second tropical system named Barry to visit the New York area.  Its moisture arrived during the evening of July 18, 2019, producing 1.82" of rain between 8 PM and midnight, with more than half of it pouring down in the initial hour (this was more rain than had fallen in the previous three weeks).  Before the rain arrived, the afternoon had been hot and steamy, with a high of 93°, dew points in the low-to-mid-70s and a heat index of 105°.  Barry 2.0's rainfall was half the amount that fell from Barry 1.0 in 2007. 

DORIAN

The northernmost bands of showers from hurricane Dorian moved through the City during the afternoon and early evening of Sept. 6, 2019, with most of the minimal rainfall pouring down between 3-4 PM (when 0.27" was measured).  With the storm situated to the south-southeast of the metro area, winds were from the east-northeast (peak gust in Central Park was 29 mph), drawing in unseasonably cool air.  Before the rain moved in at lunchtime the mercury rose to 67°, but then dropped to 58° by evening.  This was the first time since mid-June that a high and low were in the 60s/50s.

 

Hurricane dorian

FAY

This quickly developing tropical storm zipped from North Carolina to the Jersey Shore on July 10, 2020, soaking New York with 2.54" of rain, with most of it pouring down between 1:30-4:30 PM.  This amount was a record for the date, and the greatest one-day rainfall since May 2018.  The temperature and dew point were in the 70s all day long, giving the air a pronounced tropical feel.  This was the fourth "F"-named tropical system since 1970 to affect NYC, but it was the only one that didn't strike in September. 

ISAIAS

After making landfall late last night in North Carolina as a hurricane, Isaias sped through the mid-Atlantic on Aug. 4, 2020.  Because the center of the storm moved further west than was anticipated, New York City was spared heavy rain, but winds gusted to 48 mph in Central Park and 78 mph at Battery Park City in lower Manhattan (and 68, 69 and 70 mph at Newark, LaGuardia and JFK airports. respectively).  There were extensive power outages caused by downed trees.  While just 0.55" of rain fell from daybreak to lunchtime in Central Park (most between 11 AM-noon), four inches+ flooded eastern Pennsylvania.  And although it wasn't associated with Isaias, a severe thunderstorm late last night dumped the same amount of rain in about 30 minutes as fell this morning.

 

Hurricane isaias

DELTA

Moisture from the remnants of hurricane Delta moved into the area on Oct. 12, 2020 and produced a steady, but light, all-day rain that amounted to nearly one inch (0.96"); an additional 0.34" fell the following day.  Winds out of the northeast, gusting between 25-30 mph, kept the temperature unseasonably cool.  The high of 57° (which occurred shortly after midnight) was the first maximum reading in the 50s since 5/9.

ELSA

12 hours after the City was flooded by a torrential downpour during yesterday’s evening rush hour, heavy rain from the remnants of hurricane Elsa made this morning's commute a challenge (July 9, 2021).  1.79” of rain fell this morning, largely between 3-9AM.  (Elsa produced significantly more rain over Long Island, largely in the 3-4” range.)  By afternoon, the sun broke through and the temperature rose into the mid-80s.  This tropical system moved through the area one day before the one-year anniversary of tropical storm Fay lashing the metro area.

HENRI

Hurricane Henri was a huge rainmaker for the New York area.  In fact, the City received much more rain than areas that were closer to the storm’s center.  Between the evening of Aug. 21, 2021, when the rain first arrived, through early afternoon on Aug. 23, 8.19” of rain fell.  All three days had more than inch of rain (4.45”, 2.67”, and 1.07”), with more than half of the total falling in the storm's first five hours (when Henri was still a few hundred miles to the southeast, and 16 hours away from landfall in Rhode Island).  The rain was made a bit more bearable, due to the fact that there were no winds of tropical storm strength.  Henri's rainfall was the most from a hurricane/tropical storm since the "Great Atlantic Hurricane" of Sept. 12-14, 1944 flooded Central Park with 9.40".

IDA

Although Hurricane Ida, which made landfall in Louisiana four days ago as a category 4 storm, had weakened to a tropical depression when it arrived in the Mid-Atlantic on Sept. 1, 2021, what energy remained packed quite a punch as New York was flooded by extreme rainfall and lashed by tropical storm-force winds (causing more disruptions than Hurricane Henri did less than two weeks ago).  After a first round of moisture brought light showers shortly after sunrise, there was a lull until 5 PM when heavy rain moved in, becoming torrential a few hours later.  By midnight, 7.13" had been measured in Central Park – comparable to seven weeks of rain, and two-and-a-half inches more than a typical September sees in its entirety. 

At its most intense, between 9-10 PM, more than three inches poured down.  Because of this excessive rate of rainfall, the National Weather Service issued, for the first time, a Flash Flood Emergency for NYC, and subway service was suspended throughout the City.  Shockingly, thirteen residents died from flood-related causes in the five boroughs (and 25 in NJ).  Unlike Henri, which wasn’t a wind producer, Ida’s visit was accompanied by winds that gusted between 35-50 mph.

Today in New York Weather History: October 15

 

Weather_snowflakes_dry

 

October 15 is the date of New York's earliest measurable snowfall, which occurred in 1876 when 0.5" fell.  And although that was 145 years ago, NYC's earliest two-inch, four-inch and six-inch snowfalls occurred very recently - in 2011 (Oct. 29), 2012 (Nov. 7), and 2018 (Nov. 15), respectively.

 

1954

Powerful Hurricane Hazel (a 'category 4' when it made landfall in North Carolina) affected New York'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.  This was the fourth tropical system (three of them hurricanes) to impact the New York metro area this year (a tropical storm in June; Hurricane Carol on the last day of August, and Hurricane Edna in September).

1970

Today's high was 70°, the tenth day in a row with a high of 70° or warmer.  The average high during this string of days was 74° - eight degrees above average.

1973

Thirteen of the first fifteen days of October had highs in the 70s.  Today's high was 76°, twelve degrees above average.

1974

Today had the first rainfall of the month, 0.20", which moved in after 9 PM.

1975

Today was the second day in a row with sunny and unseasonably warm conditions.  Although today's high of 82° was one degree lower than yesterday, the morning low of 66° was eight degrees warmer. 

1985

Today's high was an unseasonably warm 80°, sixteen degrees above average.  This was the eighth month in a row to report a high in the 80s, joining 1945 as the only other year in which this occurred.  (These two years would later be joined by 1990.) 

1987

Today was the 15th day in a row in which the daily mean temperature never rose above average.  During these days temperatures were nearly seven degrees chillier than average.

1990

Today was the tenth day in a row with a mean temperature 10 degrees or more warmer than average - the longest such streak in the years since 1970.  During this stretch, temperatures were 13 degrees above average.  This was also the thirteenth day in a row with a high in the 70s. 

 

Day10

2009

Today was raw, windy, rainy, and unseasonably cold (high of 48°/low of 37°).  Outlying suburbs of New Jersey picked up one to two inches of snow.  This came in the midst of a nine-day stretch (10/12-19) in which temperatures were 11 degrees below the norm for mid-October. 

2014

It appeared today was going to become the latest date on record with a low in the 70s, but it was not to be as the temperature fell to 69° shortly after 11 PM during a brief downpour.  So the record set on Oct. 7, 2005 remained intact (until 2017).

Looking Back at New York Weather: September 30

 

1871

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

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

Today was the 15th day this month with a high cooler than 70°, the most of any September in the years since 1890 (thru 2021).  Before 1890, five years that had this many, or more (Sept. 1871 and 1876 had 17 such days.)

1921

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

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

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

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

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

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

Clipart_sizzlingsun1992

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

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 in the 50s.

2005

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).

 

Clipart_sunimage 

2010

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

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 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 is one month after the average date of the last reading of 90°+ (Aug. 28).

 

1975

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 nine consecutive 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

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

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

Three weeks after the remnants of Frances, 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

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).

 

Chart - most lows of 70+
2011

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

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

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

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

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).

Today in New York Weather History: September 27

 

1908

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

1975

Although it amounted to just 0.02", the rain that fell shortly before daybreak made this the ninth day in a row in which some 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

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.)

1998

Today's high of 89°/low of 69° was 15 degrees warmer than a typical day in late September.

2010

1.33" rain fell throughout the day, exceeding the total amount that fell in the previous four weeks.  One year earlier, 1.03" fell on this date.

Today in New York Weather History: September 22

 

1961

Today's high was 88°, the nineteenth day this year with a high of 88° or 89° - the most of any year in the 1950-2014 period (later tied in 2015; the average number is nine).  Additionally, there were 29 days in the 90s (the 29th would occur on 9/23).

1970

Today's high was 94°, one degree shy of the record.  And although this was a late date for a high in the 90s there would be three more to come: on 9/23 (93°), 9/25 (90°) and 9/26 (91°).  Today's reading was the hottest of the year, shared with three other dates in July and August.

 

Weather.summertime

1971

This morning's low of 58° was the first low in the 50s this month - the latest date on record for the first low cooler than 60° in September.  (Since then the latest date has been 9/17, which occurred in 2004.)

1976

Today, and the previous five days, had three matching pairs of high temperatures: 78° on the 17th and 18th; 81° on the 19th and 20th; and 68° today and yesterday.

1980

Today's unseasonably hot high of 94°, twenty-two degrees above average (but one degree shy of the record for the date) was the latest 90-degree reading since 1970 (when it occurred on Sept. 26).  It was also the 32nd 90-degree day of the year - the most since 1966 (which had 35).

1989

Powerful category 4 Hurricane Hugo made landfall near Charleston,South Carolina overnight.  The NYC metro area was prepared for 5-10 inches of rain when the storm's remnants moved up the coast, but the storm moved inland instead and stayed well to our west.  This was a great relief since six inches of rain had already fallen between Sept. 14-20.

1992

0.55'' of rain poured down between 11 PM-midnight.  (It actually fell between midnight and 1 AM on the 23rd, but the National Weather Service uses Standard Time year-round for record-keeping and doesn't recognize Daylight Saving Time).  

2005

For the past nine days, high temperatures were between 82° and 85°, averaging 10 degrees above average.

Today in New York Weather History: September 21

 

1888

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

1906

Today's low of 75° was the 61st day this year with a low of 70° or warmer.   No other year has had more days (2010 came very close, with 60).  This number was more than double the average of 30 days.

1938

New York City was spared the full fury of the history-making hurricane known as the Long Island Express as it made landfall mid-afternoon 65 miles to the east.  Still, the City had to contend with gale force winds that gusted to 60-70 mph, and four inches of rain, half of which fell between 2-5 PM.   Besides the wind and rain it was also chilly, with the temperature dropping slowly all day, from low-60s to low-50s.  Today's deluge followed two days of steady rain that amounted to 3.45".

 

Hurricane1938

1961

Less than a week after a tropical storm brushed the City, bands of rain from Hurricane Esther moved in yesterday evening, and continued through early afternoon today.  1.28” of rain fell, with 1.05" measured today; rain fell hardest between 2-4 AM, and 10 AM-noon.  (Before it made landfall in North Carolina a few days earlier, Esther was briefly a category 5 storm.)  Tropical storm force winds lashed the City around daybreak.  The rain produced by the storm accounted for 75% of the month’s rain (1.70”).

1966

The rainfall record for this date, set in 1938, was easily eclipsed when a powerful nor'easter dumped 5.54", most of it in the 12 hours between noon and midnight.  At the time this was the third greatest daily rainfall on record (it's now ranked eighth).  What made this rainfall even more notable was the fact that it came in the sixth year of a drought.  The amount of rain that fell today was greater than any month's total since November 1963.  

1971

This morning's pre-dawn rainfall of 0.50" brought the month's total rainfall to more than seven inches, the third month in a row rainfall exceeded seven inches - the only time this has happened (later joined by July-September 2021).

1979

Of the 1.88" of rain that fell today, 0.54" poured down in the hour between 11 PM-midnight (it actually fell between midnight and 1AM on the 22nd, but the National Weather Service doesn't recognize Daylight Saving Time, using Standard Time year-round).

2011

Today's 0.06" of rain in the early evening was the same amount that fell yesterday and, like yesterday, it was the first time it rained on this date in 10 years.

2020

The morning low of 49° was the first chillier than 50° reading in September in seven years, and the earliest date for this occurrence since 1993 (when it was on 9/20).  Today's low came after lows of 50° on the previous two days.  Since 2000 the average date for the first low in the 40s has been 10/5.
