South Carolina Climate

South Carolina's climate is subtropical, with plenty of humidity in its long, hot summers. Temperatures tend to be higher on the coast, with colder conditions in the mountains, though on average the winters are short and mild. With predominately low altitudes in the state, and the protection of the Appalachian Mountains screening South Carolina from cold air from the interior, average temperatures tend to range from 58°F (14°C) in the northwest, to 68°F (20°C) on the coast, though summer temperatures usually climb to 90°F (32°C) and up, particularly in the central part of the state. Rainfall occurs mostly in the spring and summer, with more precipitation occurring in summer along the coast, and in spring further inland.
