The ocean is a wonderful place to swim—if you are careful. Swimming in the ocean is not the same as swimming in a pool or lake. Wind, waves, the change of the tide, the slope of the beach and other factors can cause strong currents to be present in the water even on the calmest days. Many wind-sport enthusiasts use the areas known as Salvo Day Use Area and Haulover Day Use Area on Hatteras Island for kiteboarding and windsurfing. These areas are best used when the winds are out of the northeast and are blowing at least 10 mph. Booties should be worn to protect your feet from the broken shells which litter the bottom. Equipment is available for rent locally.
