Frost Dates in South Carolina
Frost dates track zone, so they shift across South Carolina the same way the zone number does:
- Upstate (Spartanburg, Greenville) (zone 8): average last frost Mar 8 - Mar 22, average first frost Nov 8 - Nov 22.
- Lowcountry coast (Charleston, Beaufort) (zone 9): average last frost Feb 8 - Feb 22, average first frost Dec 8 - Dec 22.
These are averages, not guarantees. For your specific frost window, use the Frost Date Calculator. For a full vegetable-by-vegetable planting calendar already calculated from South Carolina's frost dates, see the South Carolina Planting Calendar.
South Carolina's zones track elevation as much as latitude -- the state ranges from sea level along the coast up to 3,560 feet at Sassafras Mountain, per the SC Department of Natural Resources' State Climatology Office.
