Frost risk by date in Cable

Half of springs at Urbana Wwtp, OH see their last 32°F night by April 24; only one in ten is past it by April 10, and one in ten still has one after May 10. Planting tender crops after April 30 leaves a 30% risk of a frost on them, after May 4 20%, and after May 10 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 7 one year in ten, and holds off past November 2 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 April 29, 11 days before the 32°F one. The freeze-free season lasts 179 days in a typical year, shorter than at 51% of the 148 Ohio stations; it reaches 197 days one year in ten and falls short of 158 one year in ten. On average 121 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 10 days longer, to about May 4, and return around October 9. Severe cold of 16°F or below comes every winter, usually between December 6 and March 10.
