The short answer: mild winters, hot humid summers, and far less hurricane exposure than reputation suggests. Using NOAA 1991–2020 normals: Charleston averages 0.3 inches of snow a year, Columbia 1.2, Greenville 3.9 — against Boston's 49.2 and Buffalo's 95.4. Charleston's growing season runs 266 days. South Carolina recorded 30 hurricane strikes in 160 years and zero Category 5s.
| Charleston (coast) | Jan 60°/39°F · Jul 91°/74°F · 0.3" snow/yr · 266-day growing season |
|---|---|
| Columbia (midlands) | Jan 57°/35°F · Jul 93°/72°F · 1.2" snow/yr · 229-day growing season |
| Greenville (upstate) | Jan 53°/32°F · Jul 90°/69°F · 3.9" snow/yr · 224-day growing season |
A detail people find surprising: Columbia is hotter in July than Charleston (93°F vs 91°F average high), because the coast gets sea-breeze moderation. The upstate around Greenville is the coolest of the three and the only part of the state that sees meaningful snow.
Annual precipitation runs 45–53 inches depending on region — this is not a dry climate. Summers are genuinely hot and humid; that's the honest trade for the winters.
| Charleston, SC | 0.3 inches/yr |
|---|---|
| Columbia, SC | 1.2 inches |
| Greenville-Spartanburg, SC | 3.9 inches |
| Chicago, IL | 38.4 inches |
| Boston, MA | 49.2 inches |
| Minneapolis, MN | 51.2 inches |
| Buffalo, NY | 95.4 inches |
Outside January, every South Carolina monthly normal is 0.0 inches. The Lowcountry averages measurable snow about once every three years.
| Charleston, SC | 266 days (last frost Mar 7 · first frost Nov 27) |
|---|---|
| Columbia, SC | 229 days |
| Greenville, SC | 224 days |
| Boston, MA | 218 days |
| Chicago, IL | 193 days |
| Buffalo, NY | 183 days |
| Minneapolis, MN | 176 days |
Charleston gets roughly three more frost-free months than Minneapolis. USDA hardiness zones run from about 7a in the northwest mountains to 9a/9b on the southern coast.
| South Carolina | 30 strikes · 6 major · 0 Category 5 |
|---|---|
| Georgia | 23 strikes · 3 major |
| North Carolina | 51 strikes · 12 major |
| Texas | 64 strikes · 19 major |
| Louisiana | 57 strikes · 20 major |
| Florida | 114 strikes · 37 major · 2 Category 5 |
Those are NOAA counts for 1851–2010. South Carolina averages about one hurricane strike every 5.3 years and one major roughly every 27. Hurricane Hugo (September 1989, Category 4) remains the last major hurricane landfall on the South Carolina coast.
Risk is heavily coastal. FEMA's V zones (coastal high-hazard, wave action) exist only in coastal counties; inland counties carry riverine A zones only. Check the FEMA flood zone for any specific address — a Special Flood Hazard Area with a federally backed mortgage requires flood insurance. Source: NOAA.
Project Hometown SC works in three South Carolina communities. Each runs its own program, with its own resident ambassadors and its own application — those community sites are where you apply.
Living history on the Pee Dee — a 7,361-acre state park, Dizzy Gillespie's birthplace, and county median home values around $116,200.
A Fortune 500 headquarters, a university downtown, and a public STEM school Niche ranked #1 in South Carolina.
The Front Porch of the Lowcountry — an hour from Charleston, with a 600-acre wild sanctuary inside the city limits.

Barely. NOAA 1991–2020 normals: Charleston 0.3 inches a year, Columbia 1.2, Greenville-Spartanburg 3.9. Boston averages 49.2 and Buffalo 95.4. Outside January, every South Carolina monthly normal is 0.0 inches.
Hot and humid. July average highs run 90–93°F statewide, with average lows around 69–74°F. Columbia is actually hotter in July than Charleston (93° vs 91°) because the coast gets sea-breeze moderation. Annual precipitation is 45–53 inches.
Less often than reputation suggests. NOAA counted 30 hurricane strikes between 1851 and 2010 — about one every 5.3 years — including 6 major hurricanes and zero Category 5 strikes. Florida recorded 114 strikes and 37 majors in the same period. Hurricane Hugo in 1989 was the last major landfall.
Roughly 7a in the far northwest mountains to 9a/9b on the southern coast, per the 2023 USDA map. Verify your specific ZIP code on the USDA map before planning a garden around it.
