January 17, 2018 Surf Forecast
Outlook through Tuesday January 23: The new northwest swell arriving tonight will subside and shift from northwest to north by Thursday. A series of moderate northwest swells from late this week through early next week will produce surf well below the advisory threshold. Strong to near gale force trade winds will likely bring advisory-level surf to east facing shores from late Wednesday through Friday.
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.
