Swell Summary

Energy out of the NW (330-350) remains small and rather short period through Friday. Surf will then trend sharply upward late Friday through through Monday in response to a couple of swells sent toward the islands by an active pattern across the N Pac. Forerunners of the first swell in the sequence, a small, moderate period NNW (330) swell are modeled to arrive on Friday with swell peaking Saturday below the High Surf Advisory (HSA) threshold. The next swell, small to moderate and medium period out of the NNW (340), arrives quickly on its heels late Saturday likely peaking above the HSA threshold for portions of Sunday and Monday. Surf along E shores remains small to moderate as trades slightly weaken. Strengthening post-frontal NNE trades potentially bring a rapid increase in wind waves and short period fresh swell for favored exposures early next week, particularly over the western end of the state. South facing shores see small background swells through the week.
