July Weather in the Southeast U.S.

Average July Temperatures

July, the Southeast region's most popular vacation month, kicks off with Fourth of July celebrations followed by several months of summer fun. Both visitors and residents of the area head for the mountains and the beaches in droves to find some relief from the usual hot and humid weather. Temperatures in the mountains are often 5 to 10 degrees cooler than other areas, and breezes keep the coastal areas a bit more comfortable than interior areas. Rainstorms, which often move in and out fairly quickly, are common in July.

Hurricane Season

Hurricane season begins June 1 and lasts until November 30. A typical season can have as many as 11 named tropical storms and hurricanes, although statistically, July has fewer major storms than do the months of August, September, and October.
