Frost risk by date in Aubrey
Half of springs at Pilot Point Isl Du Boi, TX see their last 32°F night by March 24; only one in ten is past it by March 4, and one in ten still has one after April 13. Planting tender crops after April 1 leaves a 30% risk of a frost on them, after April 5 20%, and after April 13 10%. The 20 days between the even-odds date and the one-in-ten date is narrower than at 51% of the 339 Texas stations behind this site's ZIP pages.
In fall the first 32°F night comes by November 16 in half of years, as early as November 1 one year in ten, and holds off past December 2 one year in ten. A hard freeze of 28°F follows 11 days later, around November 27; in spring the one-in-ten date for 28°F is April 1, 12 days before the 32°F one. The freeze-free season lasts 237 days in a typical year, shorter than at 66% of the 339 Texas stations; it reaches 263 days one year in ten and falls short of 210 one year in ten. On average 45 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 4, and return around November 6. Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 72%.
