Beach Water Quality from the Florida Healthy Beaches Program

Coastal beach water samples collected every two weeks by the county health departments are analyzed for enterococci and fecal coliform bacteria. High concentrations of these bacteria may indicate the presence of microorganisms that could cause diseases, infections, or rashes. County health departments will issue health advisories or warnings when these conditions are confirmed. Learn more about the Florida Healthy Beaches Program »

Note: We are currently unable to provide you with the most recent samples and alerts on this page. Please click on the county/beach links below to find beach status and alerts.

    Bacteria

    The currently used bacterial indicators for recreational waters include total coliform, fecal coliform and enterococcus. Indicator organisms themselves are not necessarily pathogenic but their presence "indicates" or suggests recent contamination by human sewage or other waste which may result in human illness. Sources of contamination include storm water runoff, sewage overflows and feces from wild and domestic animals. Learn more about marine indicator bacteria »

      Salinity

      Salinity
      Salinity measures the amount of salts dissolved in water. An estuary can exhibit a change in salinity throughout its length as fresh water entering from the tributaries mixes with seawater from the ocean. Learn more about salinity »
