Swell Summary
A moderate size, medium to long period north northwest swell will arrive overnight into early Wednesday morning. This swell will peak through the day tomorrow, increasing the highest north and west-facing shore surf to near advisory. A similar sized west northwest swell is scheduled to arrive Thursday night and peak Friday. This swell will maintain slightly above head to double head high surf along many better exposed north-facing shores before dropping through the weekend.
Agitated, rough east seas will persist as a result of days of strong trade winds over and upstream of the islands. Strengthened trades through mid week will push this wind wave-driven swell to advisory levels.
