Forecast for Big Island Leeward

Swell Summary

A small north northwest swell that bumped up north and west facing shore surf yesterday will be fading through the morning. The next small northwest swell is expected to increase north and west facing shore surf Wednesday night through Friday. While confidence is still somewhat low this far out, the arrival of a larger Memorial Day Weekend northwest swell Sunday could significantly pick up Memorial Day surf along many northern and western exposures.

A series of small, long period southwest to south swells originating from the southern hemisphere are arriving and will persist through Friday. These swells will provide a minor boost to surf heights to near seasonal values throughout the week.

Trade winds upstream of the islands are producing moderate surf along east facing shores despite the relatively weak trade winds around the islands. This elevated eastern coast surf will fade during the second half of the week.
