Frost risk by date in Rome
Half of springs at Rome, GA see their last 32°F night by April 1; only one in ten is past it by March 13, and one in ten still has one after April 19. Planting tender crops after April 7 leaves a 30% risk of a frost on them, after April 11 20%, and after April 19 10%. The 18 days between the even-odds date and the one-in-ten date is narrower than at 41% of the 127 Georgia stations behind this site's ZIP pages.
In fall the first 32°F night comes by November 3 in half of years, as early as October 22 one year in ten, and holds off past November 18 one year in ten. A hard freeze of 28°F follows 11 days later, around November 14; in spring the one-in-ten date for 28°F is April 5, 14 days before the 32°F one. The freeze-free season lasts 217 days in a typical year, shorter than at 80% of the 127 Georgia stations; it reaches 239 days one year in ten and falls short of 194 one year in ten.
