Po‘ipu's small protected harbor cove — Surfrider BWTF community testing
Kukuiʻula Bay is the small protected cove and small-boat harbor at the western end of Po‘ipu, Kauaʻi's South Shore resort area. The latest Surfrider BWTF sample (2026-02-14) measured 20 MPN/100mL — within the 130 BAV threshold. The Hawaii DOH does not routinely test this beach.
Kukuiʻula sits on Kauaʻi's leeward South Shore — one of the driest spots on Kauaʻi. The bay is sheltered by a small breakwater and serves as a launching point for harbor cruises and snorkel tours.
BWTF's most recent reading was 20 MPN/100mL — well within the 130 BAV threshold. The dry leeward climate means bacteria-bearing storm runoff is uncommon, and the harbor concentration is small enough not to dominate the readings.
Po‘ipu's South Shore is one of the most reliably clean swimming areas on Kauaʻi. Standard 72-hour rule applies after rain; visual inspection rarely shows discoloration here.
The Hawaii Department of Health does NOT routinely test Kukuiʻula 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 Kauaʻi chapter.
BWTF samples Kukuiʻula 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.
Small sandy beach inside the breakwater. Most water activity here is boat-based — snorkel charters and harbor cruises depart from Kukuiʻula. The cove itself is shallow and calm.
Year-round in calm South Shore conditions. The Kukuiʻula Village shopping center adjacent makes it a convenient stop on a Po‘ipu day. Better dedicated swim beaches are at Po‘ipu Beach Park 5 minutes east.
Off Lawai Road in west Po‘ipu. Parking at Kukuiʻula Harbor and at the adjacent Kukuiʻula Village shopping center. Snorkel charters are popular — book in advance at the harbor or via Kauaʻi tour operators.
