Overview
- Lifeguard records this year show a sharp rise in stingray incidents with more than 3,100 reports at Bolsa Chica and Huntington State Beaches and over 900 stings in San Diego.
- NOAA-confirmed El Niño and a persistent marine heat wave have warmed nearshore waters, creating conditions that bring round stingrays closer to shore to feed and reproduce.
- Researchers say declines in predators such as sharks and sea lions, plus the rays’ preference for warm, shallow sand, have helped local stingray numbers grow.
- Beach managers and scientists are urging prevention measures like shuffling feet, issuing advisories, testing barb-resistant booties, and using hot-water immersion as first-line on-site treatment.
- Most stings cause intense pain but need only hot-water care on the beach; health officials warn to seek medical help if redness or swelling persists beyond four or five days.
