Seabrook Beach

Seabrook Beach is a sheltered beach break located along the New Hampshire coast where the Merrimack River estuary meets the Atlantic Ocean. The spot features a long sandy beach with a gentle slope, backed by residential development and salt marshes. The coastline faces northeast, with the primary water body consisting of a bay-estuary system with tidal channels visible in the surrounding marshland. Given the extremely low wind reliability (8.0%) and minimal average swell (0.72m), this is a marginal kitesurfing location dependent on specific weather patterns. Best conditions occur with northwesterly winds aligned side-shore. The shallow, protected waters and soft bottom make this suitable for beginners when conditions align, though sessions are infrequent. The estuary environment means significant tidal influence on water depth and current patterns. Kiters should account for residential constraints, limited wave development, and the need for consistent wind to generate usable conditions. This spot functions primarily as a local option for practicing technique during favorable wind windows rather than a destination break.
