Frost risk by date in Nashville
Half of springs at Rocky Mt Wilson Airport, NC see their last 32°F night by April 1; only one in ten is past it by March 16, and one in ten still has one after April 16. Planting tender crops after April 7 leaves a 30% risk of a frost on them, after April 11 20%, and after April 16 10%. The 15 days between the even-odds date and the one-in-ten date is narrower than at 57% of the 173 North Carolina stations behind this site's ZIP pages.
In fall the first 32°F night comes by November 5 in half of years, as early as October 25 one year in ten, and holds off past November 19 one year in ten. A hard freeze of 28°F follows 11 days later, around November 16; in spring the one-in-ten date for 28°F is April 6, 10 days before the 32°F one.
