The current extra large long to medium period northwest swell will continue to produce warning level surf along exposed north and west facing shores today. A High Surf Warning (HSW) remains in effect through the afternoon hours for these shorelines, and a High Surf Advisory (HSA) remains in effect for west facing shores of the Big Island. The northwest swell energy will fall below warning thresholds later tonight, and the HSW will transition to a HSA with the afternoon forecast package for the same north and west facing shores lasting through Wednesday.

Another extra large long period northwest swell will build into the region by Thursday, likely producing another round of warning level surf along exposed north and west facing shores lasting through Friday, and lingering near advisory levels Saturday before another reinforcing northwest swell briefly boosting surf heights back above warning levels on Sunday and Sunday night.

Surf along east facing shores will remain small through most of this week due shifting wind directions from the passing fronts, while no significant swells are expected to impact the state from the south.
