A northwest swell will grow today, peak tonight then gradually diminish Sunday. The advisory will be in effect until noon Sunday.
Expect surf of 12 to 16 feet along the north and west shores of Kauai and Niihau, along with the north shores of Oahu, Maui and Molokai. Meanwhile, 8 to 12 feet surf is forecasted for the west shores of Oahu and Molokai.
