Seabrook Beach is New Hampshire's most accessible surf break, sitting along the state's brief but charming Atlantic coastline near the Massachusetts border. The beach faces WNW into the Gulf of Maine, picking up northeast and east swells that wrap into the shoreline to produce mellow, punchy beach break waves ideal for beginners and longboarders. Fall brings the most consistent surf as Atlantic storm systems push energy up the coast, and the uncrowded lineup reflects New Hampshire's underrated surf culture.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
The current wave height at Seabrook Beach is 0-1ft with a 8.55s swell period. Wind is SSW at 15mph and 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 Seabrook Beach is 0-1ft, produced by a 1.6ft ESE primary swell at 9s, a 1ft SE secondary swell at 6s, a 0.3ft ESE tertiary swell at 13s, a 1.7ft SE 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.
