Duluth, GA 30097 Frost Dates
Duluth, GA: when does the frost end?
The last spring frost here typically falls around 03/25, about 209 days from today. Fall's first freeze usually shows up around 11/09, roughly 228 days after the last spring frost.
Zone 8a (10 to 15°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Duluth, not a forecast for this year.
Stretching the season past the first frost
With roughly 10 weeks until Duluth's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 03/25 isn't a guarantee
03/25 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/05 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/12 and only about 1 year in 10 sees frost after that.
