Today in New York Weather History: October 6


No rain


Since 1960, October 6 has the distinction of being the date least likely to have reported measurable rain.  (Among all years of measurement, Sept. 5 has been the date least likely to see rain.)  On this date, rain has fallen in just eleven years.  And there was a recent 17-year streak with no rain between 2002-2018. 



Today was the twenty-seventh day in a row with no measurable rain.  At the time this was the longest rain-free streak on record, and would continue to be until 1924 (it's now ranked third, behind dry spells in 1965 and 1964).  The day was also unseasonably warm, with a high/low of 84°/71°.  At the time, this was the latest date for a low in the 70s (and would remain so for nearly 100 years, until 2005, when there was a low of 70° on 10/7).


This morning's low of 58° was the mildest of October, and the second year in a row in which the mildest reading failed to reach 60°.  This was the third and last time (thru 2021) this occurred in back- to-back years.


Today had the fifth rainstorm of 1.50" or more in the past 30 days: 5.48" fell on 9/7-8; 2.01" on 9/16-17; 1.54" on 9/22; 1.51" on 9/29-30 and 1.93" on 10/5-6 (most of it fell today).  During this period, nearly 14 inches of rain was measured.  (Then less than an inch of rain would fall in the next four weeks.)


For the second day in a row the high got into the 90s (yesterday's high was a blistering 94°).  This is the only October to have more than one day in the 90s, and it was also the last time the temperature reached the 90s in October for nearly 80 years (until Oct. 2, 2019).




Under mostly clear skies today's high soared to 88°, twenty degrees above average, as the unseasonable warmth of August and September continued into October.


One day after two inches of rain fell the afternoon high was an unseasonably warm 86° (eighteen degrees above average).  A week later the mercury would once again top out at 86°.





The 0.12" of rain that fell this morning, mostly between 10-11:00, was the last time measurable rain fell on this date until 2019 (when 0.01" fell).  This was one of just five days with rain this month, which ended up as the fifth driest October on record (with 0.01" less rain than October 2000). 


The first six days of the month all had chilly highs in the 57° to 60° range, which is more typical of the last few days of October/first week of November (average highs in the first week of October range from 67° to 69°).


Although a brief evening shower amounted to just 0.01", this was the first measurable rain to fall on this date since 2001.
