Raleigh, NC 27668 Frost Dates

When can you plant in Raleigh, NC?

Zone 8a

Around 03/28 is the usual last spring frost, about 212 days away. The first fall frost typically arrives around 11/08, about 229 frost-free days later.

The USDA Plant Hardiness Zone Map puts Raleigh 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 Raleigh before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

How much risk comes with planting early here

03/28 is the middle of 30 years of NOAA records, not a promise. Plant by 03/08 and you're betting against frost in roughly 9 years out of 10. 04/12 is the safer bet, historically only a 1-in-10 chance of frost that late.
