About Lightning in South Carolina

South Carolina averages 54 thunderstorm days per year, placing it well above the national average of 25 days. Located at approximately 34°N latitude, South Carolina is a subtropical state where Atlantic sea breezes collide with inland heating, producing regular afternoon thunderstorms especially in the Midlands and Upstate regions.

In South Carolina, warm, moist air from the Gulf of Mexico combines with daytime heating to produce convective storms. Peak thunderstorm activity occurs during May through September, when conditions align for the most frequent lightning strikes. With a population of 5.1 million residents, storm awareness and lightning safety are critical concerns for anyone living in or visiting South Carolina.
