Charleston Climate and Weather
Charleston has a humid subtropical climate. Summer, between June and August, is hot and humid, with temperatures averaging between 70F (21C) and 91F (33C). The city's coastal situation helps to keep summers a bit cooler than inland.
Summer is also the wettest season, although Charleston receives significant rainfall throughout the year. Hurricanes are a threat in summer and early autumn. Winter, between December and February, is short and mild, with occasional snow flurries.
In the winter months, temperatures average between 38F (3C) and 62F (17C). Spring is generally a mild and pleasant season, perhaps better than summer because of the comfortably warm temperatures.
