Matthews, NC 28105 Frost Dates
Frost dates for Matthews, NC, ZIP 28105
Typically, the last spring freeze lands around 03/31, roughly 215 days out. The first fall frost typically arrives around 11/05, about 220 frost-free days later.
The USDA Plant Hardiness Zone Map puts Matthews 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
Zone 8a around Matthews 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 03/31 isn't a guarantee
03/31 is the middle of 30 years of NOAA records, not a promise. Plant by 03/11 and you're betting against frost in roughly 9 years out of 10. 04/16 is the safer bet, historically only a 1-in-10 chance of frost that late.
