Frost risk by date in Roseboro
Half of springs at Clinton 2 NE, NC see their last 32°F night by March 26; only one in ten is past it by March 8, and one in ten still has one after April 8. Planting tender crops after April 1 leaves a 30% risk of a frost on them, after April 5 20%, and after April 8 10%. The 13 days between the even-odds date and the one-in-ten date is narrower than at 92% of the 173 North Carolina stations behind this site's ZIP pages.
In fall the first 32°F night comes by November 7 in half of years, as early as October 26 one year in ten, and holds off past November 23 one year in ten. A hard freeze of 28°F follows 11 days later, around November 18; in spring the one-in-ten date for 28°F is March 31, 8 days before the 32°F one. The freeze-free season lasts 226 days in a typical year, longer than at 68% of the 173 North Carolina stations; it reaches 250 days one year in ten and falls short of 207 one year in ten.

Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 63%.
