Half of springs at Brockport, NY see their last 32°F night by April 24; only one in ten is past it by April 12, and one in ten still has one after May 7. Planting tender crops after April 29 leaves a 30% risk of a frost on them, after May 2 20%, and after May 7 10%. The 13 days between the even-odds date and the one-in-ten date is narrower than at 83% of the 173 New York stations behind this site's ZIP pages.
In fall the first 32°F night comes by October 30 in half of years, as early as October 12 one year in ten, and holds off past November 12 one year in ten.
