Do jellyfish and shark sightings make you less likely to visit the beach this month?

Jellyfish sightings have surged in the Newport Dunes Back Bay and near local docks. The rise in jellyfish activity comes as regional ocean temperatures have climbed 3 to 5 degrees above average.

Why it matters

An exceptionally strong El Niño event is driving up ocean temperatures and altering marine weather patterns along the coast. These warmer conditions have created a temporary environment that attracts subtropical sea species to the region.

Ocean temperatures along the Southern California coast are currently 3 to 5 degrees above average. The exact duration of these elevated temperatures is still under investigation.

The players

Newport Dunes Resort

This beachfront destination is located in Newport Beach and documented the recent increase in jellyfish activity.

The details

Newport Dunes Resort documented the jellyfish presence near the shore in a video posted on October 5, 2026. This influx of marine life coincides with broader reports of subtropical species appearing in local waters, including previous sightings of a hammerhead shark and a whale shark.

A hammerhead shark was sighted near Malibu Pier in August 2026.
A whale shark was recorded between Malibu and Santa Barbara Island on September 9, 2026.

Seasonal Patterns

The current uptick in subtropical marine species follows a pattern set by the strength of the 2026 El Niño event. This atmospheric and oceanic shift mirrors historical disruptions where warmer waters facilitated the arrival of uncharacteristic wildlife.

Residents and visitors should remain cautious near the water as stingray-related injuries have doubled at local beaches compared to the previous year. If you encounter marine life, keep a safe distance and heed any local safety advisories issued by beach authorities.

The takeaway

While the arrival of these subtropical species is temporary, the strong El Niño conditions are causing significant fluctuations in local marine environments. Beachgoers should remain vigilant as changing water temperatures often correlate with higher incidences of stings and other wildlife encounters.
