Frost risk by date in Clute
In the 82% of winters that bring a 32°F night, half of winters at Freeport 2 NW, TX see their last 32°F night by January 27; only one in ten is past it by December 24, and one in ten still has one after February 28. Counting the winters with no freeze at all, the risk of a 32°F night after February 28 is under 8% and after January 27 41%. The 32 days between the even-odds date and the one-in-ten date is wider than at 94% of the 339 Texas 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 1 in half of years, as early as December 1 one year in ten, and holds off past January 30 one year in ten. A hard freeze of 28°F is less common: it came in 42% 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 16 days longer, to about February 12, and return around December 10. A 24°F night is unusual: 11% of winters had one.
