El Niño marine surge off California
Overview
A strong El Niño event in late July 2026 warmed Pacific waters off California, drawing unusual marine species closer to shore. Scientists reported an uptick in great‑white shark sightings and the appearance of the tropical yellow‑bellied sea snake, with isolated incidents of bites near Santa Monica and San Diego.
By early August, the El Niño pattern had intensified, prompting a larger influx of young great‑white sharks and expanding the list of species to include tiger, bull and hammerhead sharks. Researchers warned that the growing “shark summer” could increase encounters for fishermen, surfers and beachgoers, while the presence of highly venomous yellow‑banded sea snakes and rising stingray injuries added further risk.
Both reports underscore how the El Niño‑driven temperature rise compounds existing climate‑change effects, reshaping California’s coastal ecosystem and heightening public‑safety concerns.
