Large waves on Oahu’s north and west shores kept lifeguards busy with 15 rescues on the North Shore and two rescues and 41 assists along the Leeward Coast today, according to the city’s Ocean Safety Division.
Lifeguards also took 4,155 preventive actions on both shores to keep people out of the water.
An 11-year-old girl was treated by lifeguards and paramedics after swallowing water at Nanakuli Beach Park and was taken to a hospital, Emergency Services spokeswoman Shayne Enright said. She was the only rescued person taken to a hospital.
