Swell Summary

The medium period easterly swell from former Tropical Cyclone Linda will keep moderate surf along east facing shores today. Surf along east facing shores will start to build today from locally generated wind waves as the remnant low moves near the islands. Surf heights may approach advisory levels for the eastern half of the island chain tonight into Sunday, before reaching the western islands Sunday night into Monday. How large the waves become is highly dependent on the eventual track and strength of the low over the coming days.

The current south swell will continue to slowly decline over the next couple of days. A series of small, moderate-period south swells will prevent surf from going flat into early next week.
