Griffin, GA 30212 Frost Dates
Griffin, GA: when does the frost end?
Around 03/26 is the usual last spring frost, about 210 days away. Fall's first freeze usually shows up around 11/06, roughly 226 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Griffin 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 Griffin's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 03/26 isn't a guarantee
03/26 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/04 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/13 and only about 1 year in 10 sees frost after that.
