Swell Summary
Outlook through Saturday December 08: The current northwest swell is expected to peak this morning, then slowly ease this afternoon through early next week. A new larger and longer period northwest swell is expected to arrive on Tuesday, peak on Wednesday, then slowly decline through the end of the work week. Surf will likely reach warning levels for north and west facing shores during this event. Breezy trades returning during the first half of next week will result in increasing surf along the east facing shores, but below high surf advisory level. Still, waters will be rough and choppy due to the large northwest swell and locally generated trade wind swell. Surf is expected to remain minimal along south facing shores through the period.
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.
