Frost risk by date in Alvord

Half of springs at Alvord 3 N, TX see their last 32°F night by April 1; only one in ten is past it by March 12, and one in ten still has one after April 21. Planting tender crops after April 7 leaves a 30% risk of a frost on them, after April 14 20%, and after April 21 10%. The 20 days between the even-odds date and the one-in-ten date is narrower than at 51% of the 339 Texas stations behind this site's ZIP pages.

In fall the first 32°F night comes by November 4 in half of years, as early as October 20 one year in ten, and holds off past November 22 one year in ten. A hard freeze of 28°F follows 9 days later, around November 13; in spring the one-in-ten date for 28°F is April 6, 15 days before the 32°F one. The freeze-free season lasts 219 days in a typical year, shorter than at 87% of the 339 Texas stations; it reaches 245 days one year in ten and falls short of 195 one year in ten. On average 73 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 11 days longer, to about April 12, and return around October 27. Severe cold of 16°F or below comes in 91% of winters, usually between December 22 and February 1.
