Swell Summary
The strong low pushing the cold front over the islands will produce a long-lived and extra-large northwest swell that will rapidly build into the islands today. The swell is expected to drop below warning thresholds Tuesday night into Wednesday. The northwest pacific remains active resulting in a large northwest swell towards the end of the week near advisory levels. Surf along south and west facing shores will also see an increase in short- period wind waves tonight into Tuesday due to the strong onshore winds.
