3/20/2026, 5:06:56 AM
Public Health Advisory Issued
Several popular beaches in California are currently under a public health advisory due to elevated levels of bacteria in ocean water. The Los Angeles County Department of Public Health issued this warning on March 17, advising residents and visitors to refrain from swimming, surfing, or engaging in water activities in the affected areas. This advisory coincides with unusually high temperatures across the West, which are reported to be as much as 35 degrees above average, particularly from Thursday to Saturday.
Affected Locations
The advisory encompasses multiple locations within Los Angeles County, including Inner Cabrillo Beach in San Pedro and Mother’s Beach in Marina del Rey, where entire swim areas are impacted. Additional warnings have been issued for parts of Santa Monica Beach, Venice Beach, and several Malibu locations. Specific areas around the Santa Monica Pier, Topanga Canyon Beach, Surfrider Beach, and Escondido State Beach are also included, particularly near storm drains and creeks where runoff can compromise water quality.
Causes of Elevated Bacteria Levels
The Los Angeles County Department of Public Health noted that elevated bacteria levels can arise from various factors, including stormwater runoff following rain events, sewage spills or leaks, and animal waste from birds, pets, or marine mammals. Urban runoff from rivers and creeks can further introduce contaminants into coastal waters. Additionally, warmer water temperatures and the decomposition of organic material can foster bacterial growth.
Health Risks
Exposure to contaminated ocean water poses several health risks, including gastrointestinal issues, fever, and infections affecting the eyes, ears, nose, or throat. Vulnerable populations, such as children, the elderly, and individuals with weakened immune systems, are at a heightened risk of illness or infection. The department conducts routine water testing at beaches and issues advisories when bacteria levels exceed safety thresholds.
Official Statements & Responses
The Los Angeles County Department of Public Health emphasized the importance of monitoring water quality, stating, "Conditions can change quickly depending on weather and environmental factors." Beachgoers are encouraged to check the county’s public health website for current conditions before visiting the coast. As of now, the advisory serves as a warning rather than a complete beach closure.
What's Next
The public health advisory will remain in effect until further notice, with updates provided on the county's public health website as conditions evolve. Residents and visitors are urged to stay informed about water quality to ensure their safety while enjoying California's beaches.
