Jacksonville, NC 28543 Frost Dates

When can you plant in Jacksonville, NC?

Zone 8b

Typically, the last spring freeze lands around 03/23, roughly 207 days out. The first fall frost typically arrives around 11/16, about 240 frost-free days later.

The USDA Plant Hardiness Zone Map puts Jacksonville in Zone 8b (15 to 20°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 11 weeks of growing season left in Jacksonville before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 03/23 isn't a guarantee

03/23 is the middle of 30 years of NOAA records, not a promise. Plant by 03/02 and you're betting against frost in roughly 9 years out of 10. 04/07 is the safer bet, historically only a 1-in-10 chance of frost that late.
