Frost risk by date in Waskom
Half of springs at Marshall, TX see their last 32°F night by March 20; only one in ten is past it by February 28, and one in ten still has one after April 7. Planting tender crops after March 31 leaves a 30% risk of a frost on them, after April 3 20%, and after April 7 10%. The 18 days between the even-odds date and the one-in-ten date is narrower than at 75% of the 339 Texas stations behind this site's ZIP pages.
In fall the first 32°F night comes by November 11 in half of years, as early as October 27 one year in ten, and holds off past November 30 one year in ten. A hard freeze of 28°F follows 13 days later, around November 24; in spring the one-in-ten date for 28°F is March 24, 14 days before the 32°F one. The freeze-free season lasts 233 days in a typical year, shorter than at 72% of the 339 Texas stations; it reaches 261 days one year in ten and falls short of 208 one year in ten.

Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 45%.
