Frost risk by date in ZIP 37335
Half of springs at Fayetteville Wtp, TN see their last 32°F night by April 7; only one in ten is past it by March 19, and one in ten still has one after April 22. Planting tender crops after April 13 leaves a 30% risk of a frost on them, after April 18 20%, and after April 22 10%. The 15 days between the even-odds date and the one-in-ten date measure how much the end of the frost season moves from year to year.
In fall the first 32°F night comes by October 28 in half of years, as early as October 13 one year in ten, and holds off past November 10 one year in ten. A hard freeze of 28°F follows 9 days later, around November 6; in spring the one-in-ten date for 28°F is April 13, 9 days before the 32°F one. The freeze-free season lasts 201 days in a typical year; it reaches 225 days one year in ten and falls short of 180 one year in ten. On average 72 nights a year drop to 32°F or below.
