Spartanburg, SC 29301 Frost Dates

When can you plant in Spartanburg, SC?

Zone 8a

Typically, the last spring freeze lands around 03/28, roughly 212 days out. The first fall frost typically arrives around 11/07, about 224 frost-free days later.

The USDA Plant Hardiness Zone Map puts Spartanburg in Zone 8a (10 to 15°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

What to do before the first frost

About 10 weeks of growing season left in Spartanburg before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 03/28 isn't a guarantee

03/28 is the middle of 30 years of NOAA records, not a promise. Plant by 03/10 and you're betting against frost in roughly 9 years out of 10. 04/14 is the safer bet, historically only a 1-in-10 chance of frost that late.
