Frost risk by date in Sutton

Half of springs at Sutton Lake, WV see their last 32°F night by April 22; only one in ten is past it by April 7, and one in ten still has one after May 11. Planting tender crops after April 30 leaves a 30% risk of a frost on them, after May 5 20%, and after May 11 10%. The 19 days between the even-odds date and the one-in-ten date is wider than at 61% of the 84 West Virginia 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 14 one year in ten, and holds off past November 7 one year in ten. A hard freeze of 28°F follows 8 days later, around November 5; in spring the one-in-ten date for 28°F is May 1, 10 days before the 32°F one. The freeze-free season lasts 187 days in a typical year, longer than at 75% of the 84 West Virginia stations; it reaches 206 days one year in ten and falls short of 165 one year in ten. On average 120 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 3, and return around October 19. Severe cold of 16°F or below comes every winter, usually between December 13 and March 1.
