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.
