Safe to Swim Hawaii

Hawaiʻi Citizen Water-Quality Testing

Our current feed includes 106 Surfrider Foundation Blue Water Task Force sites across beaches, surf breaks, and stream mouths. BWTF extends Hawaii DOH coverage, with some overlap. Each dated observation applies to its sample point and collection time. Current official advisory status must be checked separately.

How to Read These Numbers

Each row is a dated observation at one sample point. Preserve signs such as < or >: a bounded result is not an exact measurement.

The inspected feed reports an Enterococcus method code, D6503-99, but does not supply measurement or threshold units. Units therefore remain unknown here. No CFU-to-MPN conversion or threshold verdict is made.

Check the linked BWTF report for source context. A historical or recent sample cannot establish current conditions or cancel an official DOH advisory.

The Gap: Molokaʻi and Lanaʻi

Neither BWTF nor the state DOH runs routine bacteria testing on Molokaʻi or Lanaʻi. Both Maui County Council members representing those islands are pursuing community-funded testing programs to close that gap.

Note on Hawaiʻi Island (Big Island)

Big Island had a BWTF lab in earlier years but is no longer active in 2024-26. The community group Hawaiʻi Wai Ola handles some Big Island testing instead.

Attribution & Disclaimer: All BWTF data on this page is sourced from the Surfrider Foundation Blue Water Task Force at bwtf.surfrider.org. Each result links back to the lab's full report. Tests are point-in-time samples; conditions change with weather, runoff, and wave patterns. This page describes water-quality test results — not a swim recommendation. Physical hazards (shore break, rip currents, surf) are independent of bacteria readings. Always check current advisories at the Hawaii DOH Clean Water Branch before swimming.
