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.
The current wave height at Cupsogue is 3-4ft with a 8.15s swell period. Wind is SSE at 9mph and conditions are rated Poor - Fair. The forecast updates hourly so you can plan your session around the cleanest windows.
The current breaking wave height at Cupsogue is 3-4ft, produced by a 5.1ft SSE primary swell at 8s. Breaking wave height is the actual rideable wave size at the shore — calculated from offshore swell data using this spot's coastal bathymetry — not the raw buoy reading.
Based on the current 5-day forecast, the best window to surf Cupsogue is Monday from 6 AM to 9 AM with 3ft waves, a 7.5s swell period, and conditions rated Fair - Good. Check the hourly forecast for updates as conditions can shift.
Cupsogue works best with a SSE swell and NNW winds. Offshore winds groom the face of the wave, while onshore winds turn it sloppy. Cross-offshore conditions usually produce the cleanest shape.
Tide plays a big role at Cupsogue. Mid tide works for most beach breaks, while reef and point breaks often prefer higher or lower stages. Use the tide chart above to line up your session with the swell peak.
