Roxboro, NC 27583 Frost Dates
Roxboro, NC: when does the frost end?
Typically, the last spring freeze lands around 04/15, roughly 230 days out. Fall's first freeze usually shows up around 10/26, roughly 194 days after the last spring frost.
Zone 7b (5 to 10°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 Roxboro, not a forecast for this year.
Stretching the season past the first frost
With roughly 8 weeks until Roxboro's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/15 isn't a guarantee
04/15 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/27 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/30 and only about 1 year in 10 sees frost after that.
