Frost risk by date in North Port
In the 79% of winters that bring a 32°F night, half of winters at Myakka Rvr Sp, FL see their last 32°F night by February 1; only one in ten is past it by January 1, and one in ten still has one after March 3. Counting the winters with no freeze at all, the risk of a 32°F night after March 3 is under 8% and after February 1 40%. 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 6 in half of years, as early as December 5 one year in ten, and holds off past February 5 one year in ten. A hard freeze of 28°F is less common: it came in 40% 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 18 days longer, to about February 19, and return around December 27. A 24°F night is unusual: 10% of winters had one.
