Annual Water Temperature Trend

Corolla, on North Carolina’s Outer Banks, is framed by the Atlantic Ocean to the east and the shallower Currituck Sound to the west, and water temperatures vary markedly through the year. In mid-summer the ocean commonly reaches about 25–28°C, with peak August temperatures occasionally near 29°C, creating comfortable conditions for swimming. Late spring sees a steady warm-up, with ocean surface temperatures typically in the range of 15–22°C in May and June, while autumn cooling often brings September and October waters down to roughly 20–24°C and 15–20°C respectively. Winter months are much cooler; from December through February ocean temperatures usually fall to about 7–12°C. The Currituck Sound warms and cools on a different schedule because it is shallower and more protected: in summer it can be a few degrees warmer than the ocean, often reaching the upper 20s°C, while in winter it still tends to be milder than the open Atlantic.
