Swell Summary
A moderate west northwest (300-320) swell will continue to build and peak tonight before quickly dropping tomorrow. Buoy data and webcams have suggested this swell has come in larger than expected, and a High Surf Advisory is now in place for Kauai, Oahu, Molokai, and Maui until 6 AM tomorrow. This swell will then gradually fade over the weekend. A small to moderate, medium period north northwest swell (340-350) may overlap the fading west northwest swell Sunday night into Monday. In the long range, a series of small, long period northwest swell look to keep surf elevated through much of next week.
Surf along east-facing shores will remain rough and choppy but may ease a couple of notches later today and Saturday, and then again early next week as winds fluctuate in strength.
