Frost risk by date in Fort Worth

Half of springs at Fort Worth NAS, TX see their last 32°F night by March 3; only one in ten is past it by February 12, and one in ten still has one after March 22. Planting tender crops after March 11 leaves a 30% risk of a frost on them, after March 15 20%, and after March 22 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 27 in half of years, as early as November 6 one year in ten, and holds off past December 17 one year in ten. A hard freeze of 28°F follows 15 days later, around December 12; in spring the one-in-ten date for 28°F is March 10, 12 days before the 32°F one. The freeze-free season lasts 270 days in a typical year, longer than at 71% of the 339 Texas stations; it reaches 296 days one year in ten and falls short of 243 one year in ten. On average 26 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 13 days longer, to about March 16, and return around November 14. Nights of 24°F, cold enough to damage hardier plants, come in 87% of winters and 16°F in 19%.
