UPDATE: A shark estimated to be between 6 to 10 feet was spotted close to shore at Nanakuli Beach Park on Saturday, prompting urgent evacuations of swimmers and surfers. The sighting occurred at approximately 1:20 p.m., leading lifeguards to implement emergency safety protocols and clear the water.
Witnesses reported seeing the aggressive shark in both the surf and swim zones, forcing Ocean Safety crews to act quickly. Bright yellow “Shark Sighted” signs were posted along the beach to alert visitors, while patrols continued both on land and in the water. Officials stated that these warnings would remain in effect until the shark is no longer spotted.
City lifeguards emphasized the importance of safety, urging beachgoers to report any shark sightings immediately or call 911. Before re-entering the water, visitors are encouraged to check in with an on-duty lifeguard for updated conditions.
Shark sightings are not uncommon along Oʻahu’s leeward coast. The Department of Land and Natural Resources maintains a public log for shark incidents, detailing multiple reports this year alone. Safety guidelines are available for swimmers, surfers, and paddlers to help mitigate risks when sharing the ocean with marine predators.
When a shark is reported, lifeguards follow strict protocols: they clear the water, post warnings, and maintain a watchful eye until the situation is reassessed by Ocean Safety officials. Similar precautions were taken during previous sightings earlier in 2025 at Makaha and Waimea Bay.
Authorities recommend avoiding swimming alone, staying out of murky waters, and refraining from entering the ocean during dawn or dusk—times when shark activity typically increases.
For real-time updates on conditions at Nanakuli Beach Park, beachgoers should consult on-duty lifeguards or local ocean safety channels before heading back into the water. Stay safe!
