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.
