It describes a typical year, so any single year will run warmer, cooler, wetter or drier. Readings taken at an airport on the edge of town usually sit a degree or two below a dense downtown on summer nights. Charleston sees about 15.9 days a year at or above 90°F and about 90.3 days with a tenth of an inch of precipitation or more.
