Beach water quality & safety for hotel guests
📍 2424 Kalakaua Ave, Waikiki — Directly across from Waikiki Beach
Waikiki Beach in front of the Hyatt Regency has moderate water quality overall. During dry weather, conditions are generally acceptable for swimming. The primary contamination risk comes from the Ala Wai Canal, which collects stormwater and urban runoff from much of Honolulu. After significant rainfall, bacteria levels can spike dramatically.
The Hyatt Regency is positioned at the east-central section of Waikiki Beach, slightly further from the Ala Wai Canal mouth than the western sections near Fort DeRussy. This provides somewhat better conditions than Kahanamoku Beach to the west, but the entire Waikiki shoreline is affected by the same drainage system.
Based on: DOH monitoring history, Ala Wai proximity, urban stormwater drainage patterns
After heavy rain in Honolulu, the Department of Health recommends staying out of the water for at least 72 hours. Waikiki is particularly sensitive to the Ala Wai Canal, which flushes pollutants directly into the ocean near the western end of Waikiki Beach. If the water looks murky or brownish, stay out — use the hotel pool instead.
Waikiki Beach in front of the Hyatt is one of Oʻahu's most iconic swimming spots — a broad, protected sandy beach with calm, gentle waves most of the year. The offshore reef absorbs most wave energy, creating conditions suitable for beginners, families, and ocean-watchers. Lifeguards are stationed at multiple points along the beach during daytime hours.
The area in front of the Hyatt sees heavy beach activity — outrigger canoe rides, surfboard rentals, and catamaran tours all operate from this stretch. Water can be turbid from recreational activity. For cleaner water, consider taking a short cab ride to Kaimana Beach (Sans Souci) or Ala Moana Beach Park.
