Frost risk by date in Warsaw

Half of springs at Warsaw 6 SW, NY see their last 32°F night by May 7; only one in ten is past it by April 24, and one in ten still has one after May 22. Planting tender crops after May 13 leaves a 30% risk of a frost on them, after May 18 20%, and after May 22 10%. The 15 days between the even-odds date and the one-in-ten date is narrower than at 29% of the 173 New York stations behind this site's ZIP pages.

In fall the first 32°F night comes by October 10 in half of years, as early as September 27 one year in ten, and holds off past October 27 one year in ten. A hard freeze of 28°F follows 17 days later, around October 27; in spring the one-in-ten date for 28°F is May 14, 8 days before the 32°F one. The freeze-free season lasts 156 days in a typical year, shorter than at 61% of the 173 New York stations; it reaches 177 days one year in ten and falls short of 135 one year in ten. On average 157 nights a year drop to 32°F or below. Nights of 36°F, when frost can still settle on leaves in low, open spots, continue 11 days longer, to about May 18, and return around September 30. Severe cold of 16°F or below comes every winter, usually between November 25 and March 31.
