Water quality at North Kaʻanapali Beach
📍 North Kaʻanapali, West Maui
The Westin Kaʻanapali Ocean Resort Villas sits on North Kaʻanapali Beach, the northern stretch of Maui's most famous resort coastline. Water quality here is moderate-low risk — generally clean during dry weather, with some vulnerability to West Maui stream runoff after rainfall.
The northern end of Kaʻanapali is slightly further from the main resort strip and has fewer water quality monitoring points than the central beach. During normal weather, the water is clear and conditions are generally favorable for swimming and ocean activities.
Based on: DOH Kaʻanapali Beach monitoring, West Maui stream proximity, seasonal rainfall data
Stay out for at least 72 hours after heavy rain. West Maui receives more rainfall than South Maui, and streams in the area can temporarily elevate bacteria levels.
