Frost risk by date in Odessa

Half of springs at Odessa Schlemeyer Field, TX see their last 32°F night by March 19; only one in ten is past it by March 1, and one in ten still has one after April 8. Planting tender crops after March 29 leaves a 30% risk of a frost on them, after April 2 20%, and after April 8 10%. The 20 days between the even-odds date and the one-in-ten date is narrower than at 51% 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 29 one year in ten, and holds off past November 26 one year in ten. A hard freeze of 28°F follows 10 days later, around November 21; in spring the one-in-ten date for 28°F is March 27, 12 days before the 32°F one. The freeze-free season lasts 235 days in a typical year, shorter than at 69% of the 339 Texas stations; it reaches 259 days one year in ten and falls short of 212 one year in ten. On average 49 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 April 3, and return around November 3. Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 54%.
