Frost risk by date in Geneva
In the 64% of winters that bring a 32°F night, half of winters at Orlando Sanford Airport, FL see their last 32°F night by January 24; only one in ten is past it by December 29, and one in ten still has one after February 23. Counting the winters with no freeze at all, the risk of a 32°F night after February 23 is under 6% and after January 24 32%. The 30 days between the even-odds date and the one-in-ten date is wider than at 82% 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 9 in half of years, as early as December 15 one year in ten, and holds off past February 6 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 14 days longer, to about February 7, and return around January 1. A 24°F night is unusual: 3% of winters had one.
