Frost risk by date in Pensacola
Half of springs at Pensacola Regional Airport, FL see their last 32°F night by February 14; only one in ten is past it by January 21, and one in ten still has one after March 11. Planting tender crops after February 26 leaves a 30% risk of a frost on them, after March 4 20%, and after March 11 10%. The 25 days between the even-odds date and the one-in-ten date is narrower than at 49% 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 9 in half of years, as early as November 17 one year in ten, and holds off past January 10 one year in ten. A hard freeze of 28°F follows 23 days later, around January 1; in spring the one-in-ten date for 28°F is February 28, 11 days before the 32°F one. The freeze-free season lasts 301 days in a typical year, shorter than at 50% of the 102 Florida stations; it reaches 336 days one year in ten and falls short of 266 one year in ten. On average 11 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 2, and return around November 25. Nights of 24°F, cold enough to damage hardier plants, come in 54% of winters and 16°F in 3%.
