Frost risk by date in Sebring
In the 69% of winters that bring a 32°F night, half of winters at Avon Park 2 W, FL see their last 32°F night by January 28; only one in ten is past it by December 31, and one in ten still has one after February 26. Counting the winters with no freeze at all, the risk of a 32°F night after February 26 is under 7% and after January 28 35%. The 29 days between the even-odds date and the one-in-ten date is wider than at 77% 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 12 one year in ten, and holds off past February 10 one year in ten. A hard freeze of 28°F is less common: it came in 32% 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 13 days longer, to about February 10, and return around December 29. A 24°F night is unusual: 8% of winters had one.
