The rise in shark activity poses minimal risk to beachgoers, as great white sharks rarely attack humans. However, there have been isolated incidents, such as a swimmer being bitten off the Mendocino coast earlier this year. Researchers warn that fishing for sharks near piers could provoke defensive behavior, increasing the likelihood of bites. Additionally, the ongoing marine heatwave and an anticipated super El Niño cycle may attract other shark species, such as hammerheads, which have been linked to bites in the past. Overall, the presence of sharks is seen as a positive indicator of a recovering marine ecosystem, but caution is advised for those engaging in water activities.
