McDonough, GA 30252 Frost Dates
When can you plant in McDonough, GA?
Around 03/31 is the usual last spring frost, about 215 days away. The first fall frost typically arrives around 11/06, about 220 frost-free days later.
McDonough sits in USDA Zone 8a (10 to 15°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 McDonough before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 03/31 isn't a guarantee
03/31 is the middle of 30 years of NOAA records, not a promise. Plant by 03/08 and you're betting against frost in roughly 9 years out of 10. 04/16 is the safer bet, historically only a 1-in-10 chance of frost that late.
