Frost risk by date in Orlando
In the 61% of winters that bring a 32°F night, half of winters at Orlando International Airport, FL see their last 32°F night by January 25; only one in ten is past it by December 30, 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 6% and after January 25 30%. The 32 days between the even-odds date and the one-in-ten date is wider than at 97% 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 10 in half of years, as early as December 18 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 23% of winters. On average 2 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 11 days longer, to about February 5, and return around January 1. A 24°F night is unusual: 4% of winters had one.
