Forecast for Big Island Windward and Southeast

Forecast for Big Island Leeward

Swell Summary

The current northwest swell is on the decline, but a reinforcing west-northwest to northwest swell is expected to arrive later today. This will boost surf along exposed north and west facing shores to High Surf Advisory levels Sunday night and Monday. Due to the westerly component of this swell, surf heights may approach High Surf Advisory thresholds for west facing shores of the Big Island on Monday. Otherwise no significant northerly swells are expected through the week.

Short period easterly wind wave swell will remain elevated and choppy as the trade winds remain strong. As the trades strengthen even further midweek, we should see another uptick along east facing shores during the second half of the week. South-facing shore surf will remain at background levels for the next several days.
