California Shark Summer: What Beachgoers Need to Know 2026

California is preparing for its sharkiest summer in a decade, with juvenile great white sharks appearing along the coastline. Surfers, swimmers, and fishermen will share the waves with these young apex predators, but experts say there is no reason to panic. The influx is driven by warmer than usual waters from a strong El Niño, pushing young white sharks north from Mexico.

Why Are More Sharks Appearing in California?

The primary cause is the powerful El Niño weather pattern, which warms ocean temperatures off Baja California. Juvenile great white sharks, typically between 6ft and 9ft in length, are fleeing these warmer waters and seeking cooler, food-rich areas along the California coast. In 2015, the last strong El Niño, researchers observed twice as many white sharks as usual, with some establishing a nursery near Monterey Bay.

These young sharks stay close to shore to feed on fish, rays, and squid, growing safely before venturing into deeper waters. Their presence is a natural response to changing ocean conditions, not a sign of increased aggression.

Are Shark Attacks a Real Threat?

Shark incidents remain exceedingly rare in California. Since 1950, there have been just 250 recorded incidents and only 17 fatalities, according to the California Department of Fish and Wildlife. The number of deadly shark bites has stayed stable at about 2.5 per decade. Dr. Chris Lowe, director of the Shark Lab at California State University Long Beach, explains that humans don't look or sound like prey to white sharks. In his studies, sharks consistently ignore surfers, swimmers, and kayakers.

What Should Beachgoers Do?

While the risk is low, following basic safety guidelines can help you stay safe. Experts recommend avoiding swimming at dawn or dusk, staying in groups, and not wearing shiny jewelry that might attract fish. If you see a shark, remain calm and slowly back away. Do not splash or panic, as that can mimic the behavior of injured prey.

• Stay in groups – sharks are more likely to target solitary individuals.
• Avoid dawn and dusk when sharks feed most actively.
• Don't wear shiny objects that can attract fish and sharks.
• Heed local warnings and beach closures from lifeguards.

How Researchers Are Studying Shark Behavior

Scientists at the Shark Lab use drones and tracking data to monitor white shark movements. In one study, they recorded audio of surfers, swimmers, and kayakers to understand what sounds and vibrations these groups make underwater. The findings confirm that sharks are not interested in humans as a food source. Juvenile white sharks are learning what's on the menu, and humans don't fit that description.
