Swepsonville, NC 27340 Frost Dates

When can you plant in Swepsonville, NC?

Zone 8a

Typically, the last spring freeze lands around 04/06, roughly 221 days out. The first fall frost typically arrives around 11/01, about 210 frost-free days later.

The USDA Plant Hardiness Zone Map puts Swepsonville 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 9 weeks of growing season left in Swepsonville before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 04/06 isn't a guarantee

04/06 is the middle of 30 years of NOAA records, not a promise. Plant by 03/21 and you're betting against frost in roughly 9 years out of 10. 04/22 is the safer bet, historically only a 1-in-10 chance of frost that late.
