Today in New York Weather History: September 15
1914 (Tuesday)
The average high/low of the past eight days was an unseasonably cool 68°/51°, nearly ten degrees below average. This cool period wasn't associated with wet weather, as just 0.01" of rain fell.
1933 (Friday)
Yesterday's soaking, all-day rain, which totaled 2.86", continued unabated today and flooded the City with an additional 4.16" (the heaviest rain ended later in the afternoon) - and the rain would continue as showers through midday on 9/16. The day was also very chilly, with temperatures mostly in the mid-50s, nearly 20 degrees below average.
1947 (Monday)
This was the fifth day in a row with a low in the 70s. Ranging from 72° to 74°, the average low during these days was 73°, eleven degrees above average (and what you'd expect during a heat wave in July or August). Highs during these days ranged from 85° to 89°.
1970 (Tuesday)
For the fourth day in a row the low temperature was 58°, four degrees below average. Each day, however, had a different afternoon high.
1993 (Wednesday)
Today was the year's 39th, and last, day with a high of 90+, tying 1991 for the most hot days in one year. However, this year's hot days were more concentrated, occurring in a span of 128 days (between May 11 and Sept. 15) while 1991's occurred over the course of 163 days (April 8 - Sept. 17).
2007 (Saturday)
Early morning showers between 3-6 AM amounted to 0.08", making this the sixth year in a row in which rain fell on this date (and in eight of the past nine years).
2023 (Friday)
Today, with a high/low of 69°/58°, had the first high in the 60s and first low in the 50s since 6/7 and 6/10, respectively. Only three other Septembers have had their first reading in the 50s occur later (last year it happened on 9/16 and in 2016 and 1947 it fell on 9/17). And the 98 days between the years last two lows in the 50s was the second longest gap on record (behind 1996's 104 days).
1947 and 2022 are the only two Septembers where the first fifteen days (or half) of the month had no reading of 61° or colder.
