If It Looks Brown, Don't Swim
Never enter the ocean when the water appears brown or murky, even if no advisory is posted. Hawaii is often slow to test beaches and update advisories — not every beach is monitored. After heavy rain, wait at least 72 hours and until the water clears before swimming.

Historical Bacteria Risk
⚠ Historical rating — this is based on long-term testing data, not current conditions. The state of Hawaii is often slow to test beaches and update advisories. Always check the water yourself and avoid brown or murky water.
Elevated Risk 3 / 5

Hanakaoo Beach Park, also known as Canoe Beach, has a documented pattern of recurring bacteria contamination. The February 2026 reading of 1,298 enterococci per 100mL was over 10 times the recreational swimming threshold (130 CFU/100mL EPA standard) — the worst reading on record for this location.

Previous advisories were issued in 2018 (178/100mL), 2019 (238/100mL), and 2020 (137/100mL). The pattern suggests chronic infrastructure issues — urban runoff, stormwater drainage, and nearby cesspools contribute bacteria to the water, particularly after rain. This beach is located just south of the Ka'anapali resort area.

Based on: DOH Beach Advisory history (2018, 2019, 2020, 2026), Maui Now reporting, proximity to urban runoff sources

⚠️ The 72-Hour Rain Rule

The 72-hour rule is especially important at Hanakaoo. Given this beach's history of bacteria exceedances after rain, exercise extra caution. The contamination sources — stormwater drainage, cesspool overflow, and urban runoff — are all activated by rainfall. Even if the water looks clear, bacteria can persist.

Safe to Swim Hawaii is an independent passion project — it is not affiliated with the Hawaii Department of Health or any government agency. Water quality ratings on this site are estimates based on publicly available testing data and geographic analysis. They are not real-time measurements and may not reflect current conditions. “No DOH Alerts” means no advisory is currently posted — it does not mean the water was tested and found safe. DOH only monitors a fraction of Hawaii’s beaches, and some areas have no regular testing at all.

Always verify current water quality conditions with the Hawaii Department of Health Clean Water Branch before entering the water. This site is for informational purposes only and should not be the sole basis for any swimming decisions.

This site is a work in progress and we want to make it better. If you notice something that isn't working right, have a suggestion, or want to share local knowledge about a beach, please reach out.

This site does not recommend or advise anyone to swim at any beach. We share government data and geographic analysis so you can make your own informed decisions. By using this site you accept full responsibility for your own safety. See our Terms of Use for full details.
