Frost risk by date in Cuyahoga Falls

Half of springs at Stow 4 SE, OH see their last 32°F night by April 30; only one in ten is past it by April 17, and one in ten still has one after May 16. Planting tender crops after May 6 leaves a 30% risk of a frost on them, after May 10 20%, and after May 16 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 21 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 12 days later, around November 2; in spring the one-in-ten date for 28°F is May 4, 12 days before the 32°F one. The freeze-free season lasts 173 days in a typical year, shorter than at 75% of the 148 Ohio stations; it reaches 191 days one year in ten and falls short of 153 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 9, and return around October 8. Severe cold of 16°F or below comes every winter, usually between December 4 and March 18.
