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 9.75s swell period. Wind is WSW at 9mph 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 3.2ft ESE primary swell at 10s, a 0.9ft 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 Harbor Beach is Saturday from 10 AM to 1 PM with 7ft waves, a 9.75s swell period, and conditions rated Very Good. Check the hourly forecast for updates as conditions can shift.
Harbor Beach works best with a NE swell and SW 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 Harbor 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.
