Twin City, GA: when does the frost end?
Around 03/02 is the usual last spring frost, about 186 days away. Fall's first freeze usually shows up around 11/27, roughly 269 days after the last spring frost.
Twin City sits in USDA Zone 8b (15 to 20°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.
Stretching the season past the first frost
With roughly 13 weeks until Twin City's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 03/02 isn't a guarantee
03/02 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/02 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/25 and only about 1 year in 10 sees frost after that.
