Mooresville, NC 28117 Frost Dates

Mooresville, NC: when does the frost end?

Zone 8a

Around 03/24 is the usual last spring frost, about 208 days away. Fall's first freeze usually shows up around 11/08, roughly 230 days after the last spring frost.

Mooresville sits in USDA Zone 8a (10 to 15°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.

Stretching the season past the first frost

With roughly 10 weeks until Mooresville's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

Why 03/24 isn't a guarantee

03/24 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/05 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/09 and only about 1 year in 10 sees frost after that.

About 230 days separate Mooresville's last and first frost, putting it 10,305 of 40,283 ZIP codes nationally. Within NC, it ranks 212 of 1,078.
