Trinidad State Beach offers consistent surf beneath dramatic coastal cliffs in Humboldt County. The beach receives NW Pacific swells and produces mellow, workable waves across a wide sandy stretch. While more accessible than many NorCal spots, the cold water, occasional powerful surf, and shark presence require intermediate-level experience. One of the more scenic surf settings in the region.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
The current wave height at Trinidad State Beach is 1ft with a 6.7s swell period. Wind is NNW at 5mph and conditions are rated Poor. The forecast updates hourly so you can plan your session around the cleanest windows.
