Can I Swim at My Coastal Beach?

The vast majority of the time, California's waters are open and available for recreation uses visitors enjoy. Unfortunately, there are times when it is not advisable to go in the waters due to bacterial contamination.

    County health agency websites and contact information provide the most immediate information on ocean beach postings and closures.
    • Postings - Warnings to avoid contact with the water; monitoring shows bacteria levels exceed standards.
    • Closures - Prohibitions on uses of water. Imminent public health threats, such as sewage spills.
