October 22, 2018 Surf Forecast
Outlook through Monday October 29: A new long-period south-southwest swell arriving Wednesday may cause surf to approach the High Surf Advisory threshold along south facing shores starting Wednesday night. A reinforcing south swell arriving Friday will maintain elevated surf along south facing shores into next weekend. A moderate north-northwest swell arriving late tonight and Tuesday is expected to peak Tuesday night or Wednesday. This swell will slowly decline Wednesday night. A reinforcing north-northwest swell arriving Thursday will maintain moderate surf along north and west facing shores through early Saturday.
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.
