California beach safety challenged by rising shark sightings and record lifeguard rescues

Veteran shark tracker Keith Poe explained that a surge in great white shark sightings off Southern California this summer is driven by warmer ocean temperatures and abundant food, causing juvenile sharks to move northward toward the coast. Poe emphasized that these young sharks are focused on feeding and pose no direct threat to swimmers.

Meanwhile, lifeguards in Los Angeles County reported a record 1,950 ocean rescues over a single weekend, far exceeding the typical 300‑500 rescues. The unprecedented number is linked to extreme heat, a marine heat wave, and large swells generated by hurricanes off Mexico, which have created strong rip currents and waves up to 1.8 m. Lifeguard captain Pono Barnes and veteran lifeguard Maximus Oberto described the conditions as “staggering” and warned that a new heat dome will keep the coast hazardous, urging swimmers to stay near lifeguard stations.
