The water at beaches in North Carolina and South Carolina stays warm enough from May to mid-October for most people to enjoy swimming. Ocean temperatures normally peak at over 80 Â°F (high 20s Â°C) during summer. The farther south you go, the warmer the sea. The warm ocean and long stretches of sand make the beaches from Charleston to Cape Hatteras popular places for a summer vacation. But the Atlantic Ocean cools sharply in late fall. Temperatures drop as low as 46 Â°F (8 Â°C) on average in February off Cape Hatteras, making it much too chilly for swimming.
