Frost risk by date in New Caney
Half of springs at Cleveland, TX see their last 32°F night by March 7; only one in ten is past it by February 8, and one in ten still has one after March 29. Planting tender crops after March 16 leaves a 30% risk of a frost on them, after March 23 20%, and after March 29 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 20 in half of years, as early as November 2 one year in ten, and holds off past December 10 one year in ten. A hard freeze of 28°F follows 14 days later, around December 4; in spring the one-in-ten date for 28°F is March 15, 14 days before the 32°F one. The freeze-free season lasts 259 days in a typical year, longer than at 62% of the 339 Texas stations; it reaches 296 days one year in ten and falls short of 228 one year in ten. On average 30 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 March 22, and return around November 9. Nights of 24°F, cold enough to damage hardier plants, come in 80% of winters and 16°F in 9%.
