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.
