Frost risk by date in Kissimmee
In the 71% of winters that bring a 32°F night, half of winters at Kissimmee 2, 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 25. Counting the winters with no freeze at all, the risk of a 32°F night after February 25 is under 7% and after January 28 36%. The 28 days between the even-odds date and the one-in-ten date is wider than at 67% 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 6 in half of years, as early as December 17 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 31% of winters. On average 3 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 12 days longer, to about February 9, and return around December 29. A 24°F night is unusual: 6% of winters had one.
