Cupsogue is a quality beachbreak located at the western tip of Westhampton Beach on the South Shore of Long Island, New York, where the Atlantic Ocean meets Moriches Inlet. The spot picks up south and southeast swells well and produces punchy, powerful peaks that can deliver fast, hollow waves when conditions align — particularly during fall hurricane swells. Its position near the inlet creates some dynamic sandbar formations, giving surfers a variety of peaks to choose from along this scenic stretch of New York coastline.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
