Frost risk by date in Deland
Half of springs at Deland 1 SSE, FL see their last 32°F night by February 17; only one in ten is past it by January 14, and one in ten still has one after March 19. Planting tender crops after February 28 leaves a 30% risk of a frost on them, after March 8 20%, and after March 19 10%. The 30 days between the even-odds date and the one-in-ten date is wider than at 82% 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 30 in half of years, as early as December 2 one year in ten, and holds off past January 31 one year in ten. A hard freeze of 28°F follows 11 days later, around January 10; in spring the one-in-ten date for 28°F is March 1, 18 days before the 32°F one. The freeze-free season lasts 310 days in a typical year, longer than at 53% of the 102 Florida stations; it reaches 349 days one year in ten and falls short of 275 one year in ten. On average 7 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 19 days longer, to about March 8, and return around December 11. A 24°F night is unusual: 28% of winters had one.
