Frost risk by date in Dundee
In the 82% of winters that bring a 32°F night, half of winters at Mountain Lake, FL see their last 32°F night by February 4; only one in ten is past it by January 1, and one in ten still has one after March 11. Counting the winters with no freeze at all, the risk of a 32°F night after March 11 is under 8% and after February 4 41%. The 35 days between the even-odds date and the one-in-ten date is wider than at 98% 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 4 in half of years, as early as December 8 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 43% 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 21 days longer, to about February 25, and return around December 21. A 24°F night is unusual: 11% of winters had one.
