The surf will remain above the summer average Saturday, with wave faces of 3 to 6 feet on Oahu south shore beaches.
The National Weather Service said a storm in the South Pacific generated waves that began reaching all of the main Hawaiian islands Thursday.
Beach-goers can expect strong, breaking waves, shore break and rip currents that could make swimming difficult and dangerous.
People going to the beach should heed advice given by lifeguards and exercise caution, the weather service said.
