Harbor Beach is a tucked-away surf spot on the southern Maine coast near York, facing WSW into the Gulf of Maine and picking up long-traveling swells that wrap into its sheltered shoreline. The beach break offers mellow, crumbly waves that are forgiving for beginners and longboarders, though powerful northeast ground swells in autumn can push the surf to more punchy, hollow conditions. Surfing in Maine means cold water year-round, wild coastal scenery, and a refreshingly uncrowded lineup that rewards those willing to brave the chill.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
The current wave height at Harbor Beach is 5-7ft with a 10.1s swell period. Wind is WSW at 8mph and conditions are rated Very Good. The forecast updates hourly so you can plan your session around the cleanest windows.
The current breaking wave height at Harbor Beach is 5-7ft, produced by a 3.9ft ESE primary swell at 10s. 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.
