Frost risk by date in De Berry
Half of springs at Carthage, TX see their last 32°F night by March 8; only one in ten is past it by February 19, and one in ten still has one after March 31. Planting tender crops after March 18 leaves a 30% risk of a frost on them, after March 24 20%, and after March 31 10%. The 23 days between the even-odds date and the one-in-ten date is wider than at 72% 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 November 19 in half of years, as early as November 2 one year in ten, and holds off past December 8 one year in ten. A hard freeze of 28°F follows 13 days later, around December 2; in spring the one-in-ten date for 28°F is March 16, 15 days before the 32°F one. The freeze-free season lasts 255 days in a typical year, longer than at 59% of the 339 Texas stations; it reaches 283 days one year in ten and falls short of 227 one year in ten. On average 39 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 17 days longer, to about March 25, and return around November 8. Nights of 24°F, cold enough to damage hardier plants, come in 94% of winters and 16°F in 23%.
