South Carolina weather and climate

Columbia averages 1.2 inches of snow a year. Buffalo averages 95.4. Here's the rest of the picture — including the parts that aren't flattering.

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.

Temperatures by region

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.

Hurricanes: the actual record

South Carolina30 strikes · 6 major · 0 Category 5
Georgia23 strikes · 3 major
North Carolina51 strikes · 12 major
Texas64 strikes · 19 major
Louisiana57 strikes · 20 major
Florida114 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.

Where this leads

Three towns are actively recruiting new neighbors.

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.
