Frost risk by date in Palm Bay
In the 67% of winters that bring a 32°F night, half of winters at Palm Bay, FL see their last 32°F night by January 30; only one in ten is past it by January 1, and one in ten still has one after March 1. Counting the winters with no freeze at all, the risk of a 32°F night after March 1 is under 7% and after January 30 33%. 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 11 in half of years, as early as December 21 one year in ten, and holds off past February 14 one year in ten. A hard freeze of 28°F is less common: it came in 27% of winters. On average 1 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 11, and return around January 1. A 24°F night is unusual: 4% of winters had one.
