Frost risk by date in Wingo

Half of springs at Martin U Of T Branch E, TN see their last 32°F night by April 4; only one in ten is past it by March 20, and one in ten still has one after April 21. Planting tender crops after April 10 leaves a 30% risk of a frost on them, after April 16 20%, and after April 21 10%. The 17 days between the even-odds date and the one-in-ten date is narrower than at 47% of the 113 Kentucky stations behind this site's ZIP pages.

In fall the first 32°F night comes by October 28 in half of years, as early as October 15 one year in ten, and holds off past November 10 one year in ten. A hard freeze of 28°F follows 9 days later, around November 6; in spring the one-in-ten date for 28°F is April 9, 12 days before the 32°F one. The freeze-free season lasts 204 days in a typical year, longer than at 72% of the 113 Kentucky stations; it reaches 225 days one year in ten and falls short of 184 one year in ten.
