Frost risk by date in Panama City Beach
Half of springs at Panama City Bay Co Airport, FL see their last 32°F night by February 7; only one in ten is past it by January 5, and one in ten still has one after March 5. Planting tender crops after February 21 leaves a 30% risk of a frost on them, after February 27 20%, and after March 5 10%. The 26 days between the even-odds date and the one-in-ten date is wider than at 52% 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 24 in half of years, as early as November 23 one year in ten, and holds off past January 23 one year in ten. A hard freeze of 28°F follows 12 days later, around January 5; in spring the one-in-ten date for 28°F is February 22, 11 days before the 32°F one. The freeze-free season lasts 318 days in a typical year, longer than at 56% of the 102 Florida stations; it reaches 353 days one year in ten and falls short of 282 one year in ten. On average 9 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 18 days longer, to about February 25, and return around December 1. A 24°F night is unusual: 30% of winters had one.
