Frost risk by date in Galion

Half of springs at Galion Wtr Wks, OH see their last 32°F night by April 26; only one in ten is past it by April 11, and one in ten still has one after May 11. Planting tender crops after May 2 leaves a 30% risk of a frost on them, after May 6 20%, and after May 11 10%. The 15 days between the even-odds date and the one-in-ten date is narrower than at 77% of the 148 Ohio stations behind this site's ZIP pages.

In fall the first 32°F night comes by October 20 in half of years, as early as October 7 one year in ten, and holds off past November 2 one year in ten. A hard freeze of 28°F follows 11 days later, around October 31; 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 176 days in a typical year, shorter than at 66% of the 148 Ohio stations; it reaches 196 days one year in ten and falls short of 157 one year in ten. On average 130 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 5, and return around October 9. Severe cold of 16°F or below comes every winter, usually between December 5 and March 15.
