Today in New York City Weather History: July 17

1879 (Thursday)

Today's high of 79° followed yesterday's high of 98°, which was the hottest reading of the summer (and the hottest reading in three years).  Today's high occurred shortly after midnight and the temperature fell throughout the day. 

1968 (Wednesday)

After a torrid high/low of 97°/75° yesterday, today's high/low of 98°/78° would make this the hottest day of the summer.  Not only was today hotter than yesterday, it was also hotter than July 1's scorching 97°/77°. 

 

1969 (Thursday)

An evening thundershower that dropped 0.11" of rain was the first measurable rain on this date since 1952.  Also, with a high/low of 96°/76°, this would be the hottest day of the year, based on mean daily temperature.  (Although 5/29 had a high of 97°, its low was two degrees lower than today's.) 

1983 (Sunday)

For the fifth year in a row the temperature rose into the 90s on this date.  This joined another five-year streak from 1936-1940 on July 10 (later joined by streaks in 1990-1994 on July 9, and on July 7 from 2010-2014).  

1988 (Sunday)

After a steamy afternoon high of 94°, an inch of rain poured down in a 60-minute period during an early evening thunderstorm between 6:40-7:40 PM. 


1995 (Monday)

A torrential rainstorm dumped 3.36" of rain tonight between 10 PM-1 AM.  Incredibly, 2.09" fell in just one hour (10:19-11:19 PM).  At the time this was Central Park's ninth greatest rainfall in a 60-minute period (now ranked 11th). 

On this night I was attending a performance of Macbeth when the skies opened up shortly after intermission.  Soon, the rain was falling so heavily that it began dripping onto the stage!  When the play was over many of us hesitated going out into the deluge, but theater management wouldn't let us linger.  This was the biggest 24-hour rainstorm since 3.20" fell on Aug. 16-17, 1993. 

 

1996 (Wednesday)

Today's low of 74° was the warmest low temperature of the year, tying a few dates in 1976 for the distinction as the "coolest" reading to be the warmest summertime low in the 1970-2025 period.  Another low of 74° would occur on Sept. 10.  

1999 (Saturday)

The high temperature soared to 98° and was one of nine days this month with a high of 97° or hotter. 

2001 (Tuesday)

0.50" of rain fell in an hour between 6-7 PM.  This would be the biggest rainstorm of the month. 

2006 (Monday)

Today's high was 95° after a low of 77°.  The mean temperature of 86° was the warmest of the month. 

2009 (Friday)

The afternoon high of 86° was the warmest reading of the month, the coolest July maximum temperature on record. 

2018 (Tuesday)

A cold front moving into hot and very humid air triggered severe thunderstorms across the metro area in the middle of the afternoon (and a funnel cloud formed over New York Harbor).  In Manhattan, nearly two inches of rain fell between 2:30 and 3:30, which exceeded the 1.95" of rain that fell during the first sixteen days of the month.  Before the storm struck, the temperature had risen into the upper 80s and the heat index reached 100°. 

For the entirety of the storm, 2.22" was measured in Central Park, which was three times as much as what Kennedy Airport had, twice as much as Newark received and 40% more than what fell in the rain gauge at LaGuardia.  In the past six days nearly four inches of rain fell. 

 

2019 (Wednesday)

For the second year in a row more than an inch of rain fell on this date as a severe thunderstorm between 8-9 PM dumped more rain (1.14") than what fell in the previous three weeks (0.99").  Earlier in the day, sauna-like conditions prevailed as the dew point reached the mid-70s, the temperature rose to 93°, and the heat index reached 105°.  It also appeared today would be one of those rare summer days with a low of 80°+, but when tonight's storm moved in the temperature dropped to 73°. 

Rain continued after the initial storm, adding 0.68", making this the wettest day of the year (until 10/16, when 0.01" more was measured).  This moisture was from the remnants of what was hurricane Barry, which flooded Louisiana earlier in the week.  This was the second tropical storm named Barry to drench NYC; the first was in June 2007, when nearly four inches of rain fell.     

2024 (Wednesday)

A high of 90° extended the current heat wave to four days, making it this summer's third heat wave of this length. Today was also the 15th day with a high in the 90s in the past four weeks (since 6/20).  Then, tonight, a deluge after 9:30 soaked the City with 1.46" of rain, most of it pouring down in the initial hour.  This was four days after 2.06" fell at daybreak.
