Today in New York Weather History: September 22


1961 (Friday)

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 (Tuesday)

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.




1971 (Wednesday)

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 (Wednesday)

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 (Monday)

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 (Friday)

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 (Tuesday)

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 (Thursday)

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

Occasionally, there are years that share the hottest reading of the year in two calendar months (the past two years are an example). The year 1970 however shared it in three calendar months (July, August, and September). The year 1970 joins 1884 as the only two calendar years to share the hottest reading of the year in three calendar months and coincidentally, both years share the hottest reading of the year in four different calendar dates. However, 1884 shared the hottest reading of the year in June, August, and September.


2019 was the first year since 1967, and just the eleventh year overall, with no low temperatures of 70° or warmer from August 23 to September 22.

I remember going to the beach at Riis Park during the 1970 heat wave. We were all remarking about the unexpected chance to hit the beach again. It must September 26, as that was a Saturday.


2019 - for the tenth day in a row, no rain fell, the longest such streak since last December, which also lasted ten days. the last time a longer streak of this kind happened was in September-October of 2017 when there was an 18 day dry stretch.


From what I can tell Summer 2021 was the rainiest season of all time. with 29.97 inches of rain coming in Summer 2021. Summer 2021. Previous record (from what I can tell) is Summer 2011 with 28.11 inches.

For the other seasons (this isn't quite perfect, because sometimes the season changes on the 20th or 22nd).

Winter: 1978-79 - 20.96"
Spring: 1989 - 25.4"
Fall: 1983 - 25.8"


As you experienced, calculating the amounts of precipitation using astronomical seasons is a bit of a challenge, and that's why meteorological seasons are often used instead, because the number of days is fixed since it's based on calendar months. The only variance is meteorological winter when February has 29 days every four years.


the source I looked at says meteorological summer 2021 had 24.03” (second wettest) and meteorological summer 2011 had 25.23” (wettest). astronomical summer 2021 had 30.06” (wettest) and astronomical summer 2011 had 28.17” (second wettest). therefore, using astronomical or meteorological summer actually does matter very much when determining which of the two summers was the wettest and the second wettest.
