A high surf advisory has been extended until 4 a.m. Monday for the north and west shores of Oahu, Kauai, Niihau and Molokai and the north shores of Maui. The west shores of Hawaii island are also under the advisory.

Surf of 10 to 15 feet was expected on the north shores of Oahu, Molokai and Maui and the north and west shores of Kauai and Niihau, the National Weather Service said.

Surf of 8 to 12 feet was expected along the west shores of Oahu and Molokai and 6 to 10 feet along the west shores of the Big Island, the agency said.

The waves were due to diminish overnight.

Meanwhile, a surface ridge north of Kauai will bring light tradewinds to parts of the state tonight, with some windward showers possible across Maui and the Big Island.

Light and variable winds will return on Monday and persist for most of the week, with vog likely spreading over the smaller islands once again, the weather service said.
