Frost risk by date in Hastings
Half of springs at Hastings 4NE, FL see their last 32°F night by February 14; only one in ten is past it by January 11, and one in ten still has one after March 17. Planting tender crops after February 28 leaves a 30% risk of a frost on them, after March 6 20%, and after March 17 10%. The 31 days between the even-odds date and the one-in-ten date is wider than at 91% 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 November 28 one year in ten, and holds off past January 26 one year in ten. A hard freeze of 28°F follows 9 days later, around January 8; in spring the one-in-ten date for 28°F is February 28, 17 days before the 32°F one. The freeze-free season lasts 308 days in a typical year, longer than at 52% of the 102 Florida stations; it reaches 344 days one year in ten and falls short of 272 one year in ten. On average 10 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 23 days longer, to about March 9, and return around December 5. A 24°F night is unusual: 30% of winters had one.
