Pāʻia Bay

The North Shore Maui surf town's namesake bay, BWTF-tested by the Maui chapter

Community Water Testing
The Hawai‘i Department of Health does not run routine bacteria-testing here. The readings below come from the Surfrider Foundation’s volunteer Blue Water Task Force, which fills coverage gaps DOH doesn’t reach.

Pāʻia Bay is the north-facing crescent at the heart of Pāʻia town, the windsurfing-and-surf hub on Maui's North Shore. Check the Community Water Testing section for the sample date, result and full Surfrider report. A sample describes the water collected at that place and time; it does not establish today's water quality. Check the live DOH status above separately.

Why the Readings Run the Way They Do
Open-ocean exposure but seasonal stream input

Pāʻia Bay opens to the north Pacific, with trade winds and open-ocean swell. Pāʻia Stream meets the bay at its eastern end and can carry runoff after rain.

Neither open-ocean exposure nor distance from the stream establishes current bacteria levels. Check the dated community sample and current DOH advisories separately.

🌧️
After Rain — Wait Times
Light rain: 72 hours minimum, then visually verify the water has cleared.
Moderate rain: 4–7 days.
Storm or Kona low: wait until the water returns to clear blue-green visually. Can take 1–2+ weeks in extreme cases.
Testing Coverage

The Hawaii Department of Health does NOT routinely test Pāʻia Bay. The community-tested readings on this page come from the Surfrider Foundation Blue Water Task Force, a volunteer-led monitoring program run by the Surfrider Maui chapter.

BWTF samples Pāʻia Bay monthly using the IDEXX Enterolert method (MPN/100mL), and compares results against the same 130 Beach Action Value DOH uses statewide. See our overview of citizen water-quality testing in Hawaiʻi for the methodology and how BWTF data fits with DOH coverage.

Practical Notes
Where to Enter

Sandy entry from the central beach. Pāʻia Stream meets the bay at its eastern end. A single sample does not establish water quality across the bay. Winter shorebreak can be strong.

When It's at Its Best

Summer mornings (May–Sept) bring the calmest conditions and the bay turns into a swim and bodyboard spot. Winter brings powerful north swells that put the bay off-limits except for experienced surfers and lifeguarded breaks. Pāʻia town itself is a destination — windsurf/surf shops, food trucks, art galleries.

Getting There

Center of Pāʻia town off Hāna Highway. Short walk from Pāʻia town's main intersection at Baldwin Avenue. Free street parking (fills on weekends). Restaurants and showers nearby in town.
