January 12, 2019 Surf Forecast
Outlook through Saturday January 19: A large northwest swell is forecast to spread down the island chain today and tonight. The swell is running several hours behind schedule, so the peak of the swell and surf will occur around midnight tonight, then hold through Sunday. A reinforcing northwest swell, although slightly smaller, may extend the warning level surf through Monday night before the swell starts subsiding. Another large pulse will arrive from the north on Thursday night, which may lead to another High Surf Warning event. Only small background south swells should be expected.
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.
