Frost risk by date in Beaumont
Half of springs at Beaumont City, TX see their last 32°F night by February 14; only one in ten is past it by January 17, and one in ten still has one after March 11. Planting tender crops after February 26 leaves a 30% risk of a frost on them, after March 2 20%, and after March 11 10%. The 25 days between the even-odds date and the one-in-ten date is wider than at 82% 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 4 in half of years, as early as November 13 one year in ten, and holds off past January 7 one year in ten. A hard freeze of 28°F follows 24 days later, around December 28; in spring the one-in-ten date for 28°F is February 22, 17 days before the 32°F one. The freeze-free season lasts 299 days in a typical year, longer than at 86% of the 339 Texas stations; it reaches 336 days one year in ten and falls short of 261 one year in ten. On average 9 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 March 1, and return around November 22. A 24°F night is unusual: 46% of winters had one.
