Breezy tradewinds will produce rough and elevated surf along east-facing shores of most of the state through Monday afternoon, the National Weather Service said.

At about 3:30 p.m. Sunday, the Weather Service extended a high surf advisory for east shores of Kauai, Oahu, Molokai, Maui and Hawaii island until 6 p.m. Monday.

Surf was 6 to 8 feet along some east-facing shores today and forecast to be the same along east-facing shores through Monday, the Weather Service said.

Strong breaking waves and shore breaks are expected.

The weather service urged beach goers to heed the advice of lifeguards and to exercise caution.

A small craft advisory also remains in effect until 6 p.m. Monday for all Hawaiian waters, where easterly winds are 30 to 35 mph and seas are 9 to 12 feet.
