Frost risk by date in Andrews
Half of springs at Andrews, TX see their last 32°F night by March 18; only one in ten is past it by February 25, and one in ten still has one after April 9. Planting tender crops after March 30 leaves a 30% risk of a frost on them, after April 3 20%, and after April 9 10%. The 22 days between the even-odds date and the one-in-ten date is wider than at 63% 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 14 in half of years, as early as November 1 one year in ten, and holds off past November 28 one year in ten. A hard freeze of 28°F follows 11 days later, around November 25; in spring the one-in-ten date for 28°F is March 29, 11 days before the 32°F one. The freeze-free season lasts 240 days in a typical year, shorter than at 61% of the 339 Texas stations; it reaches 267 days one year in ten and falls short of 214 one year in ten. On average 59 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 April 3, and return around November 5. Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 52%.
