Beach & water quality guide — which coast to visit, top beaches, and what to expect
Both South and West Maui coasts are excellent in summer. South swells occasionally hit the south coast but are usually mild. West Maui enjoys flat calm water perfect for snorkeling at Black Rock and Kapalua Bay. Water temperatures reach their warmest (79–81°F). The Road to Hana beaches are more accessible with drier conditions.
These beaches have elevated risk factors this month. Check current conditions before you go.
Maui’s South Shore (Wailea, Kīhei) recovers fastest from rain — often within 24 hours — because it’s the driest coast. West Maui takes 48–72 hours. Rainy-day alternatives: Maui Ocean Center, Iʻao Valley (if not flooding), Lahaina town shopping and galleries, upcountry Maui farm tours.
Maui Film Festival (June) and the Kapalua Wine & Food Festival bring visitors. Slack-key guitar festivals showcase Hawaiian music. Calm ocean conditions make summer ideal for Molokini snorkel tours.
