31757, near Thomasville, GA: the frost window

Zone 9a

Typically, the last spring freeze lands around 03/11, roughly 195 days out. Fall's first freeze usually shows up around 11/21, roughly 255 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 Thomasville, not a forecast for this year.

Stretching the season past the first frost

Thomasville's growing season runs out in roughly 12 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

Why 03/11 isn't a guarantee

03/11 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/20 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/31 and only about 1 year in 10 sees frost after that.
