Aurora, NC 27821 Frost Dates
27821, near Aurora, NC: the frost window
Around 03/08 is the usual last spring frost, about 192 days away. Fall's first freeze usually shows up around 12/05, roughly 272 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Aurora in Zone 8b (15 to 20°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
Aurora's growing season runs out in roughly 14 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.
Why 03/08 isn't a guarantee
03/08 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/12 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/28 and only about 1 year in 10 sees frost after that.
