Frost risk by date in Alice
In the 76% of winters that bring a 32°F night, half of springs at Alice, TX see their last 32°F night by January 29; only one in ten is past it by December 17, and one in ten still has one after March 5. Counting the winters with no freeze at all, the risk of a 32°F night after March 5 is under 8% and after January 29 38%. The 35 days between the even-odds date and the one-in-ten date is wider than at 97% 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 December 29 in half of years, as early as November 25 one year in ten, and holds off past February 9 one year in ten. A hard freeze of 28°F is less common: it came in 34% of winters. The freeze-free season lasts 337 days in a typical year, longer than at 97% of the 339 Texas stations; it reaches 365 days one year in ten and falls short of 293 one year in ten. 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 15 days longer, to about February 13, and return around December 9. A 24°F night is unusual: 7% of winters had one.
