The current wave height at Nantasket Beach is 1-2ft with a 8.8s swell period. Wind is SW at 4mph and conditions are rated Poor. The forecast updates hourly so you can plan your session around the cleanest windows.
The current breaking wave height at Nantasket Beach is 1-2ft, produced by a 1ft E primary swell at 9s, a 0.9ft ESE secondary swell at 6s, a 0.3ft E tertiary swell at 13s, a 0.3ft 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.
