Swell Summary
The current moderate, medium period northwest (320 degree) swell will continue to build through today and hold through tonight, and combine with a locally generated medium period north (350-020 degree) swell generated by a storm force low just north of the state. Surf heights will build to high end High Surf Advisory (HSA) levels today along exposed north and west facing shores of Niihau, Kauai, Oahu, Molokai, and north facing shores of Maui and the Big Island. This north swell energy will begin to decline on Saturday.
Lows developing and moving over the northwest Pacific over the weekend and next week will generate additional northwest swells that are expected to reach the islands. These swells will maintain surf along north and west facing shores, with blocks of time when the surf will approach or exceed advisory levels.
