Current Beach Advisories

Advisories are updated daily during the swim season. Beaches are only listed here if the most recent fecal bacteria or cyanobacteria sample analysis exceeded state standards. Results are available through the OneStop database.

Beach sampling/monitoring is conducted between Memorial Day and Labor Day.

For beach and advisory details, sampling results, and yearly reports, conduct a OneStop search.

Summary reports of monitoring seasons are also available at: http://des.nh.gov/organization/divisions/water/wmb/beaches/beach_reports/index.htm .
