January 08, 2019 Surf ForecastJanuary 8, 2019, 5:00 AM HST (Updated January 8, 2019, 5:00 AM)
Outlook through Tuesday January 15: A long period north-northeast swell arriving tonight is expected to cause surf to reach the High Surf Advisory threshold along east facing shores Wednesday. This swell will slowly subside Thursday and Friday. Otherwise, small to moderate northwest swells will persist through Friday. A large northwest swell arriving late Friday night may increase surf to the High Surf Warning criteria along north and west facing shores this weekend. This northwest swell will remain elevated early next week, so advisory level surf may persist next Monday and 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.
