The National Weather Service extended a high-surf advisory for the north and west shores of Kauai and the north shores of Oahu, Molokai and Maui through 6 a.m. Tuesday.
The advisory was prompted by a large northwest swell and gusty north winds that are expected to produce waves of 10 to 15 feet through tonight.
The weather service warns of strong breaking waves, shore break, and strong longshore and rip currents that could make swimming difficult and dangerous.
Kauai ocean safety officials continued the closure of Kalihiwai Bay and all guarded north shore beaches today because of strong currents. Officials closed the beaches Saturday afternoon after several swimmers got into trouble.
“Our firefighters responded three times to swimmers being swept out of Kalihiwai Bay, and thankfully, they were all saved,” said Battalion Chief Albert Kaui in a news release. “But given today’s hazardous ocean conditions on the North Shore, everyone should exercise extreme caution near the water.”
The closure includes beaches at Kalihiwai, Kee, Haena and Hanalei.
Ocean Safety urges beachgoers to go to other guarded beaches on the island, like Lydgate, Poipu or Salt Pond.
“Check with the lifeguards before going swimming and when in doubt, don’t go out,” Kaui said.
