Frost risk by date in Parrish
In the 59% of winters that bring a 32°F night, half of winters at Parrish, 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 24. Counting the winters with no freeze at all, the risk of a 32°F night after February 24 is under 6% and after January 28 29%. The 27 days between the even-odds date and the one-in-ten date is wider than at 58% 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 18 one year in ten, and holds off past February 13 one year in ten. A hard freeze of 28°F is less common: it came in 21% 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 9 days longer, to about February 6, and return around January 2. A 24°F night is unusual: 4% of winters had one.
