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.
The current wave height at Half Moon Bay - Westhaven is 3-4+ft with a 10.5s swell period. Wind is SSE at 13mph. Conditions are rated Fair. The forecast updates hourly so you can plan your session around the cleanest windows.
The current breaking wave height at Half Moon Bay - Westhaven is 3-4+ft, produced by a 9.1ft W primary swell at 11s, a 6ft S wind swell swell at 7s, a 1.3ft SW tertiary swell at 17s, a 1.2ft SW tertiary swell at 13s. 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 Half Moon Bay - Westhaven is Thursday from 11 AM to 2 PM with 4ft waves, a 10.5s swell period, and conditions rated Fair - Good. Check the hourly forecast for updates as conditions can shift.
Half Moon Bay - Westhaven works best with a W swell and E winds. Offshore winds groom the face of the wave, while onshore winds turn it sloppy. Cross-offshore conditions usually produce the cleanest shape.

Our Half Moon Bay - Westhaven 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. We also verify our offshore swell predictions against NOAA buoy measurements daily — see our accuracy page for those swell-verification metrics (buoys measure open-water swell, not breaking surf size).
