January 23, 2019 Surf Forecast
Outlook through Wednesday January 30: A large west-northwest swell will build across the area waters today, causing surf to rise along the island’s exposed north and west facing shores. A High Surf Advisory is good for these two shores through 6 pm HST Thursday. A second west-northwest swell of slightly smaller size is slated for Thursday night and Friday. This swell may extend the advisory into Friday night. The east facing shores will have surf near advisory level today, thanks to a pocket of elevated trade wind swell generate by strong trades upwind of the islands several days ago. A foot or so of this swell may wrap into the exposed south facing shores today and Thursday, resulting in a little bump there. Otherwise, a small background south swell will maintain small surf along south facing shores through Wednesday.
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.
