Swell Summary
Outlook through Friday January 25: The current swell will shift out of the north and fade away by Monday. Surf from a west northwest swell arriving Sunday night will likely remain below the advisory threshold. Large west northwest swells peaking Wednesday and Thursday are expected to produce advisory level surf. A very large northwest swell may arrive Thursday night. Surf will increase along east facing shores over the weekend as trade winds build upstream of the area. Surf will remain very small along south facing shores.
Surf heights are forecast heights of the face, or front, of waves. The surf forecast is based on the significant wave height, the average height of the one third largest waves, at the locations of the largest breakers. Some waves may be more than twice as high as the significant wave height. Expect to encounter rip currents in or near any surf zone.
