Lifeguards from the city Ocean Safety Division provided aid to hundreds of surfers and swimmers who attempted to brave the big waves on Oahu’s southern and western shores Wednesday.

As of 4 p.m., lifeguards had assisted 14 people and rescued 88 others along the shoreline from Ala Moana to Waikiki, a city ocean safety official said. Lifeguards took an additional 500 preventive actions to keep people out of the water.

South-shore waves reached face heights of 6 to 8 feet.

Lifeguards also aided 60 people and rescued five others along the west side from Yokohama Bay to Nanakuli, and took 74 preventive actions. Waves there reached face heights of 3 to 5 feet.

The National Weather Service predicts surf today will be 7 to 10 feet along the south shore and 4 to 8 feet along the west side.

The forecast also calls for 3 to 5 feet along the eastern shore, and 2 feet or less on the north shore.

Surf is expected to diminish by Friday although a moderate south swell is expected this weekend, the weather service said.
