Frost risk by date in Gainesville
Half of springs at Gainesville 11 WNW, FL see their last 32°F night by March 4; only one in ten is past it by February 3, and one in ten still has one after March 26. Planting tender crops after March 14 leaves a 30% risk of a frost on them, after March 19 20%, and after March 26 10%. The 22 days between the even-odds date and the one-in-ten date is narrower than at 66% of the 101 Florida stations behind this site's ZIP pages, so a fixed calendar date is a gamble here.
In fall the first 32°F night comes by December 4 in half of years, as early as November 10 one year in ten, and holds off past January 6 one year in ten. A hard freeze of 28°F follows 20 days later, around December 24; in spring the one-in-ten date for 28°F is March 15, 11 days before the 32°F one. The freeze-free season lasts 274 days in a typical year, shorter than at 73% of the 102 Florida stations; it reaches 309 days one year in ten and falls short of 243 one year in ten. On average 20 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 16 days longer, to about March 20, and return around November 20. Nights of 24°F, cold enough to damage hardier plants, come in 77% of winters and 16°F in 12%.
