Frost risk by date in Cool Ridge

Half of springs at Beckley Va Hospital, WV see their last 32°F night by May 6; only one in ten is past it by April 22, and one in ten still has one after May 23. Planting tender crops after May 14 leaves a 30% risk of a frost on them, after May 18 20%, and after May 23 10%. The 17 days between the even-odds date and the one-in-ten date is narrower 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 10 in half of years, as early as September 28 one year in ten, and holds off past October 22 one year in ten. A hard freeze of 28°F follows 10 days later, around October 20; in spring the one-in-ten date for 28°F is May 15, 8 days before the 32°F one. The freeze-free season lasts 156 days in a typical year, shorter than at 95% of the 84 West Virginia stations; it reaches 177 days one year in ten and falls short of 136 one year in ten.
