Frost risk by date in Beaumont
Half of springs at Beaumont Rsch Ctr, TX see their last 32°F night by February 18; only one in ten is past it by January 20, and one in ten still has one after March 15. Planting tender crops after March 1 leaves a 30% risk of a frost on them, after March 6 20%, and after March 15 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 2 in half of years, as early as November 9 one year in ten, and holds off past January 5 one year in ten. A hard freeze of 28°F follows 27 days later, around December 29; in spring the one-in-ten date for 28°F is March 1, 14 days before the 32°F one. The freeze-free season lasts 291 days in a typical year, longer than at 83% of the 339 Texas stations; it reaches 333 days one year in ten and falls short of 258 one year in ten. On average 13 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 5, and return around November 18. A 24°F night is unusual: 43% of winters had one.
