September begins the pleasant autumn season in North Carolina, with temperatures significantly lower than the peak of summer. The temperatures scale down from the peak of summer, to register in the average range of 49°F (9.4°C) to 86°F (30°C). The precipitation is in the zone of 4" (102mm) to 7" (178mm), with partly cloudy skies between sunny days. An occasional heatwave can push the midday temperatures above 90°F (32.2°C) in many places. Tropical storms are active, and floods are frequent in the river catchment areas. The hunting and growing seasons are in full swing, and the conditions are pleasant. Fall is colorful, especially in the Appalachian Mountains in the west. Hues of crimson, orange, purple, and yellow cover the landscape. Late fall sees rapidly changing temperatures, often the fastest changes during the year. The Great Smoky Mountains is the meeting place of diverse forms of vegetation and a magical ground of different colors. September is a great time to visit North Carolina.
