Frost risk by date in Longview

Half of springs at Longview #2, TX see their last 32°F night by March 7; only one in ten is past it by February 14, and one in ten still has one after March 26. Planting tender crops after March 15 leaves a 30% risk of a frost on them, after March 19 20%, and after March 26 10%. The 19 days between the even-odds date and the one-in-ten date is narrower than at 63% of the 339 Texas stations behind this site's ZIP pages.

In fall the first 32°F night comes by November 23 in half of years, as early as November 5 one year in ten, and holds off past December 12 one year in ten. A hard freeze of 28°F follows 12 days later, around December 5; in spring the one-in-ten date for 28°F is March 14, 12 days before the 32°F one. The freeze-free season lasts 260 days in a typical year, longer than at 64% of the 339 Texas stations; it reaches 287 days one year in ten and falls short of 234 one year in ten. On average 38 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 March 21, and return around November 12. Nights of 24°F, cold enough to damage hardier plants, come in 90% of winters and 16°F in 20%.
