Frost risk by date in El Paso

Half of springs at El Paso 32 ENE, TX see their last 32°F night by March 24; only one in ten is past it by February 27, and one in ten still has one after April 10. Planting tender crops after April 2 leaves a 30% risk of a frost on them, after April 6 20%, and after April 10 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 11 in half of years, as early as October 23 one year in ten, and holds off past November 28 one year in ten. A hard freeze of 28°F follows 14 days later, around November 25; in spring the one-in-ten date for 28°F is March 29, 12 days before the 32°F one. The freeze-free season lasts 230 days in a typical year, shorter than at 76% of the 339 Texas stations; it reaches 260 days one year in ten and falls short of 202 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 9, and return around November 1. Nights of 24°F, cold enough to damage hardier plants, come in 99% of winters and 16°F in 39%.
