Is it safe to swim at the Hyatt Regency Maui?

The Hyatt Regency Maui is on Ka'anapali Beach, which has a Moderate bacteria risk rating (2 out of 5). Ka'anapali Beach proper usually tests clean, but nearby Hanakaoo Beach Park (Canoe Beach) recorded bacteria levels 10 times the safe limit in February 2026. West Maui is also more prone to brown water advisories after storms than South Maui.

Is Ka'anapali Beach cleaner than Wailea Beach?

No. Wailea Beach in South Maui consistently tests cleaner than Ka'anapali Beach. The Wailea corridor has a Low risk rating (1/5) while Ka'anapali has a Moderate rating (2/5). The difference is mainly rainfall and runoff —Â South Maui is drier with no streams. Nearby Hanakaoo Beach recorded 1,298 enterococci per 100mL in February 2026.

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.

Moderate Risk 2 / 5

The Hyatt Regency Maui sits at the south end of Ka'anapali Beach, near Black Rock (Pu'u Keka'a). Ka'anapali Beach itself usually tests fine. The concern is what's happening just down the coast.

Hanakaoo Beach Park (also called Canoe Beach), at the north end of the Ka'anapali beachwalk, recorded 1,298 enterococci/100mL in February 2026 —Â that's 10 times the safe limit. If you're walking the strip and hopping in wherever looks nice, you could end up at the wrong spot.

West Maui also gets hit by brown water advisories more often than South Maui. There's one active right now from the Feb 23 storms covering Lahaina through the north shore.

The Hyatt's location near Black Rock is the better end of the strip —Â more ocean flushing, further from the Hanakaoo problem area.

Based on: DOH monitoring, Hanakaoo Feb 2026 advisory (1,298/100mL), brown water advisory frequency, West Maui rainfall

⚠️ The 72-Hour Rain Rule

The Hawaii Department of Health recommends staying out of the ocean for at least 72 hours after heavy rain, even if the water looks clear. Bacteria and pollutants from runoff can linger in the water longer than the brown color does.
