Forecast for Big Island Windward and Southeast

Forecast for Big Island Leeward

Swell Summary

Surf along exposed north and west facing shores will peak today just below High Surf Advisory levels as a long period northwest swell fills in. This swell will then trend downward by Wednesday. A more significant northwest to north-northwest swell is expected to move into the islands late Wednesday night through the second half of the week. Surf heights will likely exceed warning levels during the peak of this event from late Thursday through Friday, with swell heights decreasing through the upcoming weekend. Another overlapping moderate long period northwest swell will build in this weekend, possibly peaking at low end HSA thresholds by Sunday.

Surf along east facing shores will begin to ease through Wednesday as the trade winds diminish. Surf along south facing shores should return to background levels by Wednesday.
