Garner, NC 27603 Frost Dates

Frost dates for Garner, NC, ZIP 27603

Zone 8a

Typically, the last spring freeze lands around 03/28, roughly 212 days out. The first fall frost typically arrives around 11/09, about 227 frost-free days later.

Zone 8a (10 to 15°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 Garner, not a forecast for this year.

What to do before the first frost

Zone 8a around Garner has about 10 weeks left before the first fall frost — that's the usual window to get a cold frame up if you want to keep harvesting past it.

Why 03/28 isn't a guarantee

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.
