Los Angeles County Department of Public Health issued a beach advisory on Tuesday, August 25, 2026, urging residents to refrain from swimming, surfing and other water‑related activities at seven county beaches. The warning follows recent water testing that revealed bacterial concentrations above the levels permitted by state health standards.
The department said that samples taken from the seven locations showed elevated bacteria counts that exceed the thresholds set to protect public health. Officials noted that the unusually high temperatures recorded over the past week can foster faster bacterial growth in coastal waters, contributing to the unsafe conditions observed.
The advisory applies to all Los Angeles County residents who use the identified beaches for recreation. While the specific beach names were not disclosed, the health agency emphasized that the precautionary measure is temporary and will remain in effect until follow‑up testing confirms that water quality has returned to acceptable levels. The department indicated it will continue to monitor the sites and issue updates as new data become available.
Residents are encouraged to stay informed through official county communications and to avoid any direct contact with the water at the affected sites. The health department’s action reflects its ongoing commitment to safeguard community health by responding promptly to environmental factors that may compromise beach safety.
The warning comes as local officials grapple with a heat wave that has pushed temperatures above seasonal norms, a condition known to accelerate microbial proliferation in marine environments. By issuing the advisory, the Los Angeles County Department of Public Health aims to prevent potential illness and ensure that beachgoers can enjoy coastal recreation safely once water quality improves.
