Swell Summary
Outlook through Sunday January 27: Surf along north and west facing shores will gradually rise through the first half of the week, likely reaching advisory levels for north and west facing shores by Tuesday night, then near warning levels Wednesday into Thursday as moderate to large overlapping northwest swells move through. A large reinforcement out of the northwest will be possible Friday into the weekend. A small to moderate east swell is expected by midweek, which will lead to rising surf along east facing shores Tuesday through midweek.
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.
