Frost risk by date in Columbus
Half of springs at Columbus Metro Airport, GA see their last 32°F night by March 5; only one in ten is past it by February 11, and one in ten still has one after March 24. Planting tender crops after March 14 leaves a 30% risk of a frost on them, after March 18 20%, and after March 24 10%. The 19 days between the even-odds date and the one-in-ten date is wider than at 60% of the 127 Georgia stations behind this site's ZIP pages.
In fall the first 32°F night comes by November 23 in half of years, as early as November 7 one year in ten, and holds off past December 18 one year in ten. A hard freeze of 28°F follows 19 days later, around December 12; in spring the one-in-ten date for 28°F is March 14, 10 days before the 32°F one. The freeze-free season lasts 265 days in a typical year, longer than at 89% of the 127 Georgia stations; it reaches 295 days one year in ten and falls short of 238 one year in ten.

Nights of 24°F, cold enough to damage hardier plants, come in 88% of winters and 16°F in 18%.
