Jefferson, GA 30549 Frost Dates
Jefferson, GA: when does the frost end?
The last spring frost here typically falls around 03/31, about 215 days from today. Fall's first freeze usually shows up around 11/06, roughly 222 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Jefferson in Zone 8b (15 to 20°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
Stretching the season past the first frost
With roughly 10 weeks until Jefferson's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 03/31 isn't a guarantee
03/31 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/12 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/14 and only about 1 year in 10 sees frost after that.
