South Carolina Climate

For most people, South Carolina’s humid, subtropical climate is a welcome breath of fresh air, and as such, many people have made their way to the South to bask in its glorious weather. 

However, there is one exception that occurs in the Blue Ridge Mountains, since it carries pockets of Oceanic climate. While mild winters dominate in the southern and western parts of the state, cool and sometimes cold winters are quite normal in the state’s northwestern area. 

This is especially true in areas more than 600 feet in elevation. Furthermore, there is an average of 40 to 80 inches of rain annually, which can potentially reach 100 inches or more in the Appalachian temperate rainforest located in the upper regions of South Carolina. There are, however, few things to look out for including: 

  • Hurricanes
  • Thunderstorms
  • Heavy rainfall (occasionally)
  • Flooding as a result of storms
  • Tornadoes during spring and summer months
