Frost risk by date in Tallahassee

Half of springs at Tallahassee, FL see their last 32°F night by March 11; only one in ten is past it by February 18, and one in ten still has one after March 30. Planting tender crops after March 19 leaves a 30% risk of a frost on them, after March 23 20%, and after March 30 10%. The 19 days between the even-odds date and the one-in-ten date is narrower than at 88% of the 101 Florida stations behind this site's ZIP pages.

In fall the first 32°F night comes by November 21 in half of years, as early as November 3 one year in ten, and holds off past December 14 one year in ten. A hard freeze of 28°F follows 15 days later, around December 6; in spring the one-in-ten date for 28°F is March 17, 13 days before the 32°F one. The freeze-free season lasts 255 days in a typical year, shorter than at 91% of the 102 Florida stations; it reaches 286 days one year in ten and falls short of 226 one year in ten. On average 27 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 14 days longer, to about March 25, and return around November 9. Nights of 24°F, cold enough to damage hardier plants, come in 88% of winters and 16°F in 16%.
