Pohaku Park, locally known as S Turns for the surf spot just offshore, is a small West Maui shoreline park north of central Lahaina. The latest Surfrider BWTF sample (2026-04-15) measured 10 MPN/100mL — within the 130 BAV threshold. The Hawaii DOH does not routinely test this beach.

Why the Readings Run the Way They Do
Open coast, no major streams, post-fire watershed

Pohaku Park sits on the open West Maui coast with no major stream input directly on the beach. The shoreline is rocky-sandy, with the S Turns reef break offshore. BWTF readings here have been at or near 10 MPN/100mL — well within the 130 BAV threshold.

The area is part of the post-fire recovery zone but has been relatively unaffected by the runoff that hit Front Street and Mala Ramp further south. Open-coast exposure means good water exchange.

After heavy rain, the smaller drainages along the coastal road can carry runoff. Standard 72-hour rule applies. Better swimming options are at Lahaina's calmer beaches; Pohaku is primarily a surf-spot access.

🌧️
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 Pohaku Park (S Turns). 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 Pohaku Park (S Turns) 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

Rocky-sandy entry. The S Turns surf break is a paddle out from the south end. Not a swimming beach in any conventional sense — the rocky shoreline is for surfers and shore-watchers.

When It's at Its Best

Summer south swells and winter west wraps both produce S Turns waves. The park is small and quiet — locals and surfers more than tourists. Sunset is excellent.

Getting There

Off Front Street north of Lahaina, near the Lahaina Cannery Mall area. Limited roadside parking. Easy to combine with Mala Ramp 5 minutes south for a full Lahaina-coast loop.
