Frost risk by date in Lubbock
Half of springs at Lubbock WFO, TX see their last 32°F night by March 24; only one in ten is past it by March 4, and one in ten still has one after April 15. Planting tender crops after April 2 leaves a 30% risk of a frost on them, after April 7 20%, and after April 15 10%. The 22 days between the even-odds date and the one-in-ten date is wider than at 63% 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 11 in half of years, as early as October 28 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 April 1, 14 days before the 32°F one. The freeze-free season lasts 233 days in a typical year, shorter than at 72% of the 339 Texas stations; it reaches 257 days one year in ten and falls short of 205 one year in ten. On average 61 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 14 days longer, to about April 7, and return around November 2. Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 72%.
