Frost risk by date in Pierson
In the 80% of winters that bring a 32°F night, half of winters at Crescent City, FL see their last 32°F night by February 1; only one in ten is past it by January 3, and one in ten still has one after February 28. Counting the winters with no freeze at all, the risk of a 32°F night after February 28 is under 8% and after February 1 40%. The 27 days between the even-odds date and the one-in-ten date is wider than at 58% 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 January 8 in half of years, as early as December 10 one year in ten, and holds off past February 7 one year in ten. A hard freeze of 28°F is less common: it came in 41% of winters. On average 4 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 17 days longer, to about February 18, and return around December 23. A 24°F night is unusual: 12% of winters had one.
