California Sees Juvenile Great White Surge as El Niño Pushes Sharks North Since February
1 articles · Updated · The Guardian · Jul 14
Summary
Juvenile great whites began appearing off California in February—weeks earlier than the usual April start—signaling what scientists say could be one of the state's sharkiest summers in a decade.
El Niño is driving the shift: warmer waters off Mexico are pushing young white sharks north into cooler California shallows, echoing 2015, when researchers saw roughly twice as many along the coast.
State officials already tightened beach and pier fishing rules last month to reduce accidental hooking, after reporting a significant rise in human interactions with white sharks in Southern California.
Those juvenile aggregations can grow larger, spread as far north as Santa Cruz and Monterey Bay, and linger later in El Niño years; hammerheads, bull sharks and tiger sharks may also follow warm-water prey.
Risk to people remains low despite the increase: California has recorded fewer than 250 shark incidents since 1950, including 17 fatalities, and researchers say white sharks usually recognize humans are not prey.

2026 Sees Record Juvenile Great White Shark Sightings in California: Climate Change, Public Safety, and Ecological Shifts
Overview
In 2026, California saw an unprecedented surge in juvenile great white shark sightings, with even 10-foot sharks becoming a common sight for marine safety teams. This increase is linked to warming ocean waters from El Niño and marine heatwaves, which have shifted shark habitats and boosted their prey, like stingrays. As the public is not used to seeing sharks so often, there is a growing need for education and new safety measures. Scientists are investigating the causes behind more frequent shark encounters, while communities and officials work together to ensure both public safety and healthy marine ecosystems.
