San Diego Beaches Closed

- Recent winter storms from February 16-19, 2026, brought significant rainfall to the San Diego area, with some mountain areas receiving over three inches of precipitation. This substantial rainfall increases urban runoff, which is the primary cause of elevated bacteria levels in coastal waters. - The San Diego County Department of Environmental Health and Quality has issued a general rain advisory for all coastal beaches, urging the public to avoid swimming, surfing, and diving within 72 hours of rainfall. This is a standard precautionary measure as storm runoff can carry bacteria from various sources, including animal waste and soil, into the ocean. - As of February 21, 2026, specific advisories for bacteria levels exceeding state health standards are in effect for several beaches, including the San Luis Rey River Outlet, Batiquitos Lagoon Outlet, La Jolla Cove, and Children's Pool. The public can get real-time updates on beach closures and advisories from the county's official website, sdbeachinfo.com. - Illnesses associated with swimming in contaminated ocean water can include stomach flu, skin rashes, and infections of the eyes, ears, and respiratory tract. The county utilizes a rapid, DNA-based water testing method called digital droplet polymerase chain reaction (ddPCR) to provide same-day results on water quality. - While storm-related closures are typically temporary, San Diego County has faced persistent beach closure issues, particularly in the South Bay, due to cross-border pollution from the Tijuana River. This has led to some shorelines, like the Tijuana Slough, being closed for extended periods. - Tourism is a major economic driver for San Diego, generating over $22 billion in fiscal year 2024 and supporting one in eight jobs. Beach closures, especially during peak seasons, can negatively impact local businesses that rely on beach visitors, with some businesses in affected areas reporting significant revenue losses during prolonged closures.
