Swell Summary

Short period NNW (330-350) swell has filled in and is likely near its peak this afternoon. This swell will fade during Thursday. A small, long period NNW swell (330) will fill in Thursday night and peak Friday, keeping surf along N and W shores elevated. Surf will then trend sharply upward late Friday 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 moderate, long period NNW (330) swell will arrive late Friday with swell peaking Saturday near or below the High Surf Advisory (HSA) threshold. The next small to moderate, medium period NNW (340) swell will arrive quickly late Saturday. This swell will likely peak above the HSA threshold. Surf along E shores will remain small to moderate through the week. Strengthening post-frontal NNE trades may 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 will see a slight boost in surf today as a small, long period south swell fills in before slowly fading Thursday through the rest of the week.
