Increase in Stingray Stings Reported in Southern California Due to Warmer Waters

This year, Southern California is experiencing a notable rise in stingray stings, with over 3,100 incidents reported at Bolsa Chica and Huntington State Beaches. This figure is double the total for all of 2025, and the year is not yet over.

The increase in stings is linked to warmer ocean temperatures, which have remained consistently in the 60s. Bryan R. Etnyre, a state park superintendent, noted that the warmer waters have contributed to more people and stingrays being in the same areas. Additionally, a decline in the populations of natural predators like sharks and sea lions has allowed stingray numbers to grow.

Experts indicate that the current conditions, exacerbated by El Niño, are leading to an influx of stingrays closer to shore, resulting in a higher likelihood of encounters. Chris Lowe, a marine biology professor, explained that during El Niño events, stingrays can become so numerous that they cover the ocean floor.
