August is warm in the summer of North Carolina with at least 8 hours of daily sunshine. The average high temperatures are in the 70°F (21.1°C) to 90°F (32.2°C) range, while the average low temperatures are between 56°F (13.3°C) to 67°F (19.4°C). The coastal belt is the wettest in the state with 7" (178mm) of rainfall, including 6.9" (175mm) in Cape Hatteras and 7.4" (188mm) in Wilmington. Occasional rough weather is on the cards due to the mixing of warm and cold currents near the coast of North Carolina. Light sweatshirts are better to ward off the humidity and heat during the day. Wear large-brimmed hats and sunglasses while outdoors during the afternoons. Forests have many shady trees, but grasslands offer little shade during the midday heat. A cool lake or a swimming hole is a great spot to relax when the sun rays are intense. Mountain air is cool, and the coast has relatively lower temperatures than the interior. The temperatures drop gradually in North Carolina by the end of August.
