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 2-3ft with a 6.3s swell period. Wind is WSW at 15mph. Conditions are rated Very Poor. The forecast updates hourly so you can plan your session around the cleanest windows.
The current breaking wave height at Cupsogue is 2-3ft, produced by a 2.3ft ESE wind swell swell at 6s, a 1.5ft SE secondary swell at 9s, a 1.1ft SW wind swell swell at 2s. 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 Sunday from 1 PM to 4 PM with 2ft waves, a 6.3s swell period, and conditions rated Fair. 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.

The prime season at Cupsogue is fall, when swell direction, wind patterns, and water temps line up most consistently. Outside the peak season you can still score, but you'll need to watch the forecast closely for the right windows.
Common hazards at Cupsogue include strong currents, rip currents near inlet, shifting sandbars, crowds during peak swells, cold water in winter and spring. Always check conditions before paddling out, respect local etiquette, and never surf alone if you're unfamiliar with the break.
Our Cupsogue forecast uses NOAA GFS and other weather models combined with spot-specific bathymetry to calculate breaking wave heights. Short-range (1-3 day) forecasts are most reliable; extended forecasts show general trends. We also verify our offshore swell predictions against NOAA buoy measurements daily — see our accuracy page for those swell-verification metrics (buoys measure open-water swell, not breaking surf size).
