Frost risk by date in Nacogdoches
Half of springs at Nacogdoches, TX see their last 32°F night by March 13; only one in ten is past it by February 21, and one in ten still has one after April 6. Planting tender crops after March 23 leaves a 30% risk of a frost on them, after March 31 20%, and after April 6 10%. The 24 days between the even-odds date and the one-in-ten date is wider than at 76% 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 17 in half of years, as early as November 1 one year in ten, and holds off past December 5 one year in ten. A hard freeze of 28°F follows 14 days later, around December 1; in spring the one-in-ten date for 28°F is March 20, 17 days before the 32°F one. The freeze-free season lasts 248 days in a typical year, shorter than at 50% of the 339 Texas stations; it reaches 278 days one year in ten and falls short of 218 one year in ten. On average 41 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 17 days longer, to about March 30, and return around November 6. Nights of 24°F, cold enough to damage hardier plants, come in 95% of winters and 16°F in 16%.
