Frost risk by date in Snyder

Half of springs at Snyder, TX see their last 32°F night by March 27; only one in ten is past it by March 6, and one in ten still has one after April 14. Planting tender crops after April 3 leaves a 30% risk of a frost on them, after April 7 20%, and after April 14 10%. The 18 days between the even-odds date and the one-in-ten date is narrower than at 75% of the 339 Texas stations behind this site's ZIP pages.

In fall the first 32°F night comes by November 10 in half of years, as early as October 28 one year in ten, and holds off past November 24 one year in ten. A hard freeze of 28°F follows 10 days later, around November 20; in spring the one-in-ten date for 28°F is April 2, 12 days before the 32°F one. The freeze-free season lasts 227 days in a typical year, shorter than at 79% of the 339 Texas stations; it reaches 252 days one year in ten and falls short of 204 one year in ten. On average 71 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 11 days longer, to about April 7, and return around November 1. Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 79%.
