The climate of South Carolina (United States of America)
The state of South Carolina is located in the southeastern part of the United States on the Atlantic Ocean. South Carolina can be divided into four regions. The southeastern part of the state is part of the Atlantic Coastal Plain. Further into the interior the Sandhills can be found, ancient dunes from what used to be South Carolina’s coastline. In the northwestern part of the state Piedmont can be found. This is a plateau which mainly consists of green, rolling hills. The most northwestern part of the state consists of mountains and is part of the Blue Ridge Mountains. According to the Köppen climate classification South Carolina has a warm maritime climate, type Cfa. The highest mountain in the state is Sassafras Mountain with an altitude of 1,090 meters. Because of this there are no big differences in temperatures. Contrasts in temperatures and the weather are biggest during the winter when it may get cold in the interior while temperatures along the coast remain above freezing point.

Summers in South Carolina are warm with average temperatures of 29-33 degrees Celsius (84-92 degrees Fahrenheit) in June, July and August. During the summer nighttime temperatures are about 20 degrees Celsius (68 degrees Fahrenheit). In the city it may be even warmer because the streets and concrete buildings radiate warmth. Spring and fall are fairly warm as well. In March and November average maximum temperatures are around 20 degrees Celsius (68 degrees Fahrenheit). In April and October temperatures are even around 25 degrees Celsius (77 degrees Fahrenheit). South Carolina is a sunny state with 2,700 to more than 3,000 hours of annual sunshine. May June and July are the sunniest months, January and February get the least amount of sunshine. This is mainly caused by the fact that days are shorter during the winter. However, with 6 hours of sunshine per day out of a possible 9-10 hours of daily sunshine winters are still fairly sunny.

Precipitation is quite evenly spread out over the year. The state gets 1,100-1,300 millimeters of annual precipitation divided over 110 days with precipitation. Most precipitation can be recorded during the summer. This is because of a higher chance of thunderstorms which cause high precipitation figures. From June till December there is a risk of tropical storms and depressions. These storms may cause hurricanes in South Carolina as well. These storms may cause a lot of damage because of fierce winds and a lot of precipitation within a short period of time.
