Frost risk by date in Wadsworth

Half of springs at Chippewa Lake, OH see their last 32°F night by April 29; only one in ten is past it by April 15, and one in ten still has one after May 15. Planting tender crops after May 5 leaves a 30% risk of a frost on them, after May 9 20%, and after May 15 10%. The 16 days between the even-odds date and the one-in-ten date is narrower than at 53% of the 148 Ohio stations behind this site's ZIP pages.

In fall the first 32°F night comes by October 19 in half of years, as early as October 5 one year in ten, and holds off past November 1 one year in ten. A hard freeze of 28°F follows 13 days later, around November 1; in spring the one-in-ten date for 28°F is May 3, 12 days before the 32°F one. The freeze-free season lasts 172 days in a typical year, shorter than at 77% of the 148 Ohio stations; it reaches 191 days one year in ten and falls short of 152 one year in ten. On average 133 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 9 days longer, to about May 8, and return around October 8. Severe cold of 16°F or below comes every winter, usually between December 3 and March 18.
