Richmond Hill, GA 31324 Frost Dates
Richmond Hill, 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 11/30, roughly 270 days after the last spring frost.
Zone 9a (20 to 25°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 Richmond Hill, not a forecast for this year.
Stretching the season past the first frost
With roughly 13 weeks until Richmond Hill'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 02/04 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.
