Los Angeles County health officials have issued a public health advisory for several California beaches due to elevated bacteria levels in the ocean water. The warning, updated on March 17, advises residents to avoid swimming, surfing, or playing in the water at affected locations. This surge in contaminants coincides with a massive heat wave pushing temperatures 35 degrees above average across the West.
The advisory covers high-traffic areas including Santa Monica Beach, Venice Beach, and Mother’s Beach in Marina del Rey. Recent water samples showed bacteria levels exceeding state health standards, which may increase the risk of illness. “Swimming in water with bacteria can make you sick or cause skin infections,” the Los Angeles County Department of Public Health told Fox News Digital.
Health officials noted that the pollution is often driven by urban runoff from storm drains and creeks, along with animal waste and sewage leaks. The record-breaking heat is also a factor, as warmer water temperatures can promote the rapid growth of harmful bacteria. Children, the elderly, and those with weak immune systems are at the highest risk for infections of the eyes, ears, nose, and throat.
Exposure to contaminated ocean water can lead to a range of illnesses, including stomach issues and fever. The department conducts routine water testing at beaches throughout the region and issues advisories when levels rise above safety thresholds. Conditions can change quickly depending on weather and environmental factors.
Beachgoers are encouraged to check current conditions through the county’s public health website before heading to the coast. The advisory remains a warning rather than a full beach closure, but it comes as temperatures are expected to peak between Thursday and Saturday. The county’s website is updated as conditions change to keep the public informed.
