January 15, 2018 Surf Forecast
Outlook through Sunday January 21: As the current northwest swell gradually diminishes below warning levels on Monday, advisory-level surf along north and west shores will likely continue through Tuesday. A short-lived pulse of northwest swell may continue the advisory level surf on Wednesday, with this swell diminishing Thursday and Friday. Strong to near gale force trade winds near and upwind of the islands will likely bring high surf to east facing shores from 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.
