The South Carolina Coastal Plain accounts for almost two-thirds of the state’s area and can be broken up into two parts;
- the Inner South Carolina Coastal Plain; the area that connects with the Piedmont Plateau
- the Outer South Carolina Coastal Plain; the area that meets the ocean
From north to south, South Carolina’s coast measures 187 miles long.
The Outer Coastal Plain is mostly flat and swampy, comprising of many islands, marshy areas, bays, and inlets.
The Inner Coastal Plain dries out quite a bit and becomes a land of gently rolling hills and forested land that are cut through by rivers heading to the Atlantic ocean.
The Coastal Plain starts at sea level at the coast and rises to about 400 feet in the west.
Temperatures on the Coastal Plain vary with distance to the ocean. Locations closest to the ocean experience more moderate temperatures. The as a result of the cooling effects of the sea breezes. And greater proximity to the water than locations farther inland.
