During the winter of 2021, February became the 36th month (since 1869) to have 20 inches or more of snow fall in Central Park. This was the seventeenth February to gain this distinction, by far the most of any month (January's had eight occurrences; December's had six; and March, five). Thirty winters have had one of these snowy months, and three have had two (winters of 1978, 1996, and 2011). 19 of the months with 20"+ had more than 25" (including Feb. 2021). And four had 30" or more. The snowiest month of them all is February 2010, which reported 36.9". Below are more observations about these snow-choked months:
- The first month with 20" or more snowfall was December 1872, when 27.0" was reported. Despite February being the month most likely to have 20"+ snow, it didn't have its first overly snowy month until 1894, which was later than the first 20"+ occurrence for December, January or March. (November and April have never had 20" or more; however, November 1898 came very close, with 19.0". The most snow in April was in 1875, when 13.5" was measured.)
- The most consecutive winters to have a month with 20"+ snow is just two, which has happened five times, most recently during the winters of 2010 and 2011. The most consecutive winters without one of these snowy months is twelve, from 1936 thru 1947. And there have been three ten-year gaps.
- The most days of measurable snow during a month with 20"+ is eleven, which occurred in March 1916 (25.5" fell) and February 1920 (25.3"). The fewest days of measurable snow during a 20"+ month is two, in February 2006, when one storm accounted for all of the month's 26.9" (at the time, New York's biggest snowfall on record). And in January 2016 there were three days of snow, with 27.5" of the month's 27.9" falling on two of the days (which supplanted February 2006's snowfall as New York's biggest of all time).
- Nine of the thirty-six excessively snowy months had no snowfalls of a foot or more; five had biggest snowfalls that were less than ten inches. The smallest biggest snow was 7.0" in Dec. 1904, followed by March 1916, whose biggest accumulation was 7.6".
- In a winter with a month of 20"+ snow, the least total snowfall for the entire winter was the winter of 1979, which had 29.4"; the 20.1" that fell during February of that winter comprised slightly more than two-thirds of the winter's total. And in the winter of 1925, 29.6" of snow fell, of which January 1925 accounted for all but 2.2".
- Two of New York's ten snowiest winters had no months with 20" or more: 1874-75 is ranked seventh, and 1960-61 is the City's ninth snowiest winter.
- All but five of the thirty-six months were colder than average, including the coldest month on record, February 1934 (which had 27.9" of snow), the coldest March on record (1888, 22.3"), and fifth coldest December (1872, 27.0") and March (1916, 25.5"). The most above-average month to have more than twenty inches of snow is December 1948 (+3.9 degrees), followed by February 1983 (+3.0 degrees); January 2016 (+1.9 degrees); February 2006 (+0.4 degrees); and February 1994 (+0.2 degrees).
- Finally, "honorable mentions" go to December 2003, which had 19.8", and January 2014, which had 19.7".
