Swell Summary

Surf along north facing shores will trend higher starting this morning as a moderate size, medium to long period north northeast swell arrives. This swell will increase surf along north and west facing shores through Wednesday before fading away from Wednesday night into Thursday. Surf heights will flirt with High Surf Advisory levels along north facing shores on Tuesday and Wednesday. The next northwest swell will boost surf heights across the islands will arrive on Friday with surf heights trending higher for all north and west facing shores. This new northwest swell will peak on Saturday, and last through Sunday. East facing shores will see rough choppy surf through Wednesday with some wrap around energy from the northerly swell.
