Water Temperature: Daily Trends, Historical Records, and Forecast

✅ As of today, the minimum water temperature is above 82°F (28°C). This is very warm water, which may feel almost hot to most people. Swimming in such conditions is perfect for those seeking relaxation and comfort in the water. These waters are often preferred for relaxation in hot weather, as the water temperature does not cool the body significantly. However, it is important to remember that in such warm waters, caution is necessary, as prolonged exposure without rest can lead to overheating.

It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

Annual Water Temperature Trend

Carolina Beach, on the southern end of the Outer Banks near Wilmington, North Carolina, is a classic Atlantic barrier-island destination with broad sandy shorelines and a temperate coastal climate. Sea surface temperatures follow a distinct seasonal pattern: in winter months water typically cools to around 10–15 °C, early spring sees a gradual rise into the low-to-mid teens, and by late spring temperatures move into the high teens to low twenties. Peak summer conditions usually bring the warmest waters, commonly ranging from about 22–29 °C, while autumn waters slowly cool back into the mid-to-high teens—generally between 16–22 °C—before winter returns. Local variations occur with weather, tides and currents, so short-term shifts of a few degrees are normal.
