Swell Summary
A north swell is in the process of peaking this early Friday morning. It has been running foot or two above WaveWatch III guidance. Moderate size surf will continue mainly across the north facing shores today, subsiding to small to moderate Saturday. This swell will then be reinforced Saturday night by longer period moderate to large northwest to north swell, where a High Surf Advisory (HSA) is likely along north and west facing shores. This swell will be diminishing Monday, with the surf barely be hanging on to advisory level. A large pulse comes in late Monday night and Tuesday, warranting a High Surf Warning for the north and west facing shores of most islands. This swell will be subsiding gradually Tuesday night through Wednesday. Along the south facing shore, a small south swell of 12 to 13 second period will continue into the weekend, before fading. A small boost to the south facing shores is slated for Wednesday of next week as an out-of-season 15 second pulse arrives. Surf along east facing shores will be trending down and becoming flat over the weekend as the trade wind gradually give way to light and variable winds.
