BEACH annual report

Our Beach Environmental Assessment, Communication & Health, or BEACH, program ensures that marine water is safe to swim and play in and informs the public if water doesn't meet swimming standards.

Out of the 57 beaches sampled in 2023, 86 percent were considered passing beaches. A beach is considered passing if it has no more than one sampling event that exceeds the swimming standard.

You can look up your local beach and see how clean it was during 2023 with county-by-county links below. Also, you can compare 2023 to previous years with our summary bar chart below.

Keeping beaches safe

From Memorial Day through Labor Day in 2023, our scientists and county and local BEACH partners sampled 57 public beaches on marine waters for bacterial contamination. We collected water samples from high-use beaches weekly or biweekly to test for enterococcus, a type of fecal bacteria. High enterococcus levels are linked to swimmer illness. This information helps health officials issue swimming advisories.
