Fortress is a lesser-known surf spot tucked along the eastern tip of New York near Montauk, facing NNW toward Block Island Sound and exposed to swells wrapping around from the Atlantic. The break picks up energy from northeast and south swells that refract around the point, producing punchy, hollow beach break waves that reward surfers willing to make the trek. Its relative remoteness keeps crowds thin, making it a prized find for New York surfers seeking uncrowded conditions during the fall swell season.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
The current wave height at Fortress is 2-3ft with a 6.6s swell period. Wind is SW at 11mph 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 Fortress is 2-3ft, produced by a 1.9ft SSE primary swell at 7s, a 1.2ft W wind swell swell at 3s. 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 Fortress is Thursday from 6 AM to 9 AM with 2ft waves, a 7.6s swell period, and conditions rated Fair. Check the hourly forecast for updates as conditions can shift.
Fortress 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 Fortress. 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.
