Nahant is a rocky peninsula jutting into Massachusetts Bay north of Boston, offering a raw and exposed surf experience that lights up during northeast and east swells generated by Atlantic storms. The spot faces nearly due east at roughly 82 degrees, allowing it to capture open-ocean energy that wraps around the rocky shoreline and produces punchy, powerful waves over a hard rock bottom. Nahant is a true New England gem — cold, honest, and rewarding for surfers willing to suit up in thick rubber and navigate a rugged coastal setup.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
The current wave height at Nahant is 5-6ft with a 10.05s 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 Nahant is 5-6ft, produced by a 3.4ft E 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.
Based on the current 5-day forecast, the best window to surf Nahant is Saturday from 9 AM to 12 PM with 5ft waves, a 10.05s swell period, and conditions rated Very Good. Check the hourly forecast for updates as conditions can shift.
Nahant 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 Nahant. 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.

Common hazards at Nahant include rocks, cold water, strong currents, shore break, kelp, heavy wetsuits required. Always check conditions before paddling out, respect local etiquette, and never surf alone if you're unfamiliar with the break.
Our Nahant 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. See the forecast accuracy card above for per-spot and regional performance metrics.
