Frost risk by date in El Paso

Half of springs at El Paso International Airport, TX see their last 32°F night by March 2; only one in ten is past it by February 12, and one in ten still has one after March 19. Planting tender crops after March 9 leaves a 30% risk of a frost on them, after March 13 20%, and after March 19 10%. The 17 days between the even-odds date and the one-in-ten date is narrower than at 86% of the 339 Texas stations behind this site's ZIP pages.

In fall the first 32°F night comes by November 20 in half of years, as early as November 6 one year in ten, and holds off past December 2 one year in ten. A hard freeze of 28°F follows 11 days later, around December 1; in spring the one-in-ten date for 28°F is March 7, 12 days before the 32°F one. The freeze-free season lasts 261 days in a typical year, longer than at 65% of the 339 Texas stations; it reaches 284 days one year in ten and falls short of 237 one year in ten. On average 42 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 March 18, and return around November 10. Nights of 24°F, cold enough to damage hardier plants, come in 97% of winters and 16°F in 19%.
