Frost risk by date in Arlington
Half of springs at Arlington Municipal Airport, TX see their last 32°F night by March 9; only one in ten is past it by February 18, and one in ten still has one after March 28. Planting tender crops after March 16 leaves a 30% risk of a frost on them, after March 20 20%, and after March 28 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 21 in half of years, as early as November 3 one year in ten, and holds off past December 7 one year in ten. A hard freeze of 28°F follows 13 days later, around December 4; in spring the one-in-ten date for 28°F is March 14, 14 days before the 32°F one. The freeze-free season lasts 256 days in a typical year, longer than at 60% of the 339 Texas stations; it reaches 282 days one year in ten and falls short of 229 one year in ten. On average 36 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 15 days longer, to about March 24, and return around November 8. Nights of 24°F, cold enough to damage hardier plants, come in 94% of winters and 16°F in 26%.
