Half Moon Bay - Westhaven sits along the rugged Washington coast near Westport, facing ESE into the protected waters of Grays Harbor's outer edge, where swell wraps around the bay to produce punchy, workable beach break waves. This stretch of Washington coastline picks up consistent northwest and west swells generated by North Pacific storms, delivering rideable surf especially in the fall and winter months when swell energy is at its peak. The remote nature of this corner of Washington keeps crowds minimal, making it a rewarding find for surfers willing to explore beyond the better-known Westport breaks nearby.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
