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 1-2ft with a 4.5s swell period. Wind is E at 5mph. Conditions are rated Poor. The forecast updates hourly so you can plan your session around the cleanest windows.
The current breaking wave height at Seabrook Beach is 1-2ft, produced by a 2ft ESE wind swell swell at 5s, a 1.4ft ESE secondary swell at 9s. 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 Seabrook Beach is Friday from 6 AM to 9 AM with 2ft waves, a 6.2s swell period, and conditions rated Poor - Fair. Check the hourly forecast for updates as conditions can shift.
Seabrook Beach works best with a E swell and W 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 Seabrook Beach. 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.

Our Seabrook Beach 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).
