Climate Darlington has a humid subtropical climate (Köppen Cfa) typical of the Carolinas. Summers are hot with frequent thunderstorms breaking up the humid heat. In late summer where the Southern 500 is run, the humidity leads to frequent rain delays and difficult environments for drivers, team personnel and spectators. This leads to the event being hosted as a night race. Winters are mostly mild, but being inland there are occasional cold snaps. Darlington has a rainy climate, although normal for the region. Most years have no snow accumulation due to the mild temperatures and cold temperatures are associated with dry weather. In spite of this, Darlington has occasionally recorded some minor inches of depth during brief snowfalls.
