Average Outer Banks Ocean Water Temperatures

Boardwalk to Beach Outer Banks NC

No one likes dipping their toes in cold ocean water!

Fortunately, vacationers to North Carolina’s Outer Banks can enjoy warm Atlantic Ocean water many months out of the year, with the highest temperatures occurring during the months of July and August.

For the rest of the year, when it’s too cold to go for a swim wearing just a pair of board shorts, there are plenty of local surf shops with cold water gear – wet suits, gloves, headcovers, and boots.

Below is a table with a breakdown of average ocean water temperatures during the year on the Outer Banks. Hopefully, this helps you plan your vacation!
