Frost risk by date in Wheeler

Half of springs at Shamrock #2, TX see their last 32°F night by April 9; only one in ten is past it by March 26, and one in ten still has one after April 26. Planting tender crops after April 16 leaves a 30% risk of a frost on them, after April 20 20%, and after April 26 10%. The 17 days between the even-odds date and the one-in-ten date is narrower than at 86% of the 339 Texas stations behind this site's ZIP pages.

In fall the first 32°F night comes by October 30 in half of years, as early as October 17 one year in ten, and holds off past November 11 one year in ten. A hard freeze of 28°F follows 7 days later, around November 6; in spring the one-in-ten date for 28°F is April 17, 9 days before the 32°F one. The freeze-free season lasts 202 days in a typical year, shorter than at 94% of the 339 Texas stations; it reaches 224 days one year in ten and falls short of 181 one year in ten. On average 97 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 20, and return around October 22. Severe cold of 16°F or below comes every winter, usually between December 10 and February 21.
