Jellyfish sightings rise at Newport Dunes

Jellyfish sightings have increased in and around Newport Dunes in Newport Beach in recent weeks as Southern California coastal waters run warmer than average, KTLA reported.

The sightings matter for Orange County beachgoers because jellyfish have been seen in the Back Bay and near docks, and stings can cause pain, swelling and other symptoms.

KTLA reported that Newport Dunes Resort posted social media video Monday showing jellyfish close to shore. Officials have also reported multiple sightings in the Back Bay and around the docks in recent weeks.

The increase comes as climatologists say a strong El Niño is developing in the eastern tropical Pacific, KTLA reported. National Oceanic and Atmospheric Administration data shows Southern California coastal waters are running 3 to 5 degrees above normal.

Warmer water can bring subtropical marine life into Southern California, according to KTLA. The station reported that a rare hammerhead shark was seen near the Malibu Pier in August, and a pilot recorded a whale shark between Malibu and Santa Barbara Island on September 9.

KTLA also reported that stingray barb injuries at local beaches have doubled from last year, citing lifeguard data. Early fall can bring some jellyfish to local waters, but officials believe the warmer conditions tied to El Niño may be contributing to the increase.

The Mayo Clinic advises people stung by jellyfish to remove visible tentacles with tweezers, soak the affected skin in hot water and use hydrocortisone cream or ointment, according to KTLA.

Beachgoers in Newport Beach should watch for jellyfish near calm bay waters and docks as warmer ocean conditions continue.
