Swell Summary

Outlook through Thursday April 26: Rough, moderate surf will persist along east facing shores through this weekend. Strengthening trades will likely cause surf to reach the High Surf Advisory criteria along east facing shores early next week. The current northwest swell will peak Friday, and then slowly lower this weekend. A moderate reinforcing northwest swell arriving late Sunday is expected to peak Monday, then gradually decline Tuesday and Wednesday. Small south swells will maintain modest surf along south facing shores through early next week.
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.
