Smyrna, GA 30348 Frost Dates
When can you plant in Smyrna, GA?
Typically, the last spring freeze lands around 03/24, roughly 208 days out. The first fall frost typically arrives around 11/08, about 231 frost-free days later.
Smyrna 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.
What to do before the first frost
About 10 weeks of growing season left in Smyrna before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 03/24 isn't a guarantee
03/24 is the middle of 30 years of NOAA records, not a promise. Plant by 03/02 and you're betting against frost in roughly 9 years out of 10. 04/10 is the safer bet, historically only a 1-in-10 chance of frost that late.
