There are no marine alerts posted at this time.
Swell Summary
Outlook through Sunday February 25: Moderate northwest swells will continue through early Tuesday. A longer period west-northwest swell arriving late Tuesday may result in advisory level surf along north and west facing shores Wednesday. This swell will gradually subside Thursday, but another reinforcing west- northwest swell will arrive Thursday night, before fading Friday into next weekend. A short-period east swell will gradually increase through Monday night, with surf likely reaching the High Surf Advisory threshold along east facing shores starting Tuesday.
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.
