Oak Ridge, NC 27310 Frost Dates
Oak Ridge, NC: when does the frost end?
The last spring frost here typically falls around 03/30, about 214 days from today. Fall's first freeze usually shows up around 11/05, roughly 220 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Oak Ridge in Zone 8a (10 to 15°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
Stretching the season past the first frost
With roughly 10 weeks until Oak Ridge's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
How much risk comes with planting early here
03/30 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/12 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/14 and only about 1 year in 10 sees frost after that.
