Kihei, Wailea, and Makena — water quality overview, best spots to swim and snorkel, and what to watch for
Maui’s south shore stretches roughly 20 miles from Maʻalaea in the north down through Kihei, Wailea, and Makena to the edge of Ahihi-Kinaʻu Natural Area Reserve. It’s the leeward side of Haleakalā — sheltered from the northeast trade winds, sunny most days, and generally the most consistently swimmable coastline in Hawaii.
Water quality varies by area. The built-up Kihei corridor has more runoff risk after rain. Wailea and Makena, with newer development and more open ocean exposure, tend to have better water quality. This guide covers the key beaches in each area.
The three Kamaole parks are the heart of Kihei’s swimming scene. Staffed with lifeguards, sandy entries, and good facilities. Kamaole III is the largest and historically the cleanest. After heavy rain, storm drains in residential Kihei can affect water quality at all three parks — follow the 72-hour rule.
The northern Kihei areas are closer to residential development and the Maʻalaea Harbor area. Water quality can be more variable here, especially after rain. Check DOH advisories before swimming at Cove Park or Kalepolepo Beach.
One of Maui’s most beautiful and well-maintained beaches. Fronts the Four Seasons and Grand Wailea resorts. Wide sandy beach, calm water most days, good for swimming and stand-up paddleboard. Public beach access via parking lot on Wailea Alanui Drive. Water quality is generally very good with open ocean exposure and newer resort-era infrastructure.
Adjacent beaches separated by a rocky point with excellent snorkeling. The rocky edge between Ulua and Mokapu has fish, turtles, and good visibility on calm days. Calm enough for beginning snorkelers on most days.
Less crowded than central Wailea beaches. Rocky entry on the south end with good snorkeling. Fronts the Fairmont Kea Lani. Public access parking is limited — arrive early.
One of Maui’s most spectacular beaches — wide, long, undeveloped. Water quality is generally good with open ocean exposure and no development runoff. However, Big Beach has a powerful shorebreak on south and west swells that can be dangerous. Many visitors are surprised by the force of the waves. Check surf reports before swimming.
The best shore snorkel entry on Maui’s south shore for many. Rocky entry with good visibility, regular sea turtle sightings, and rich marine life. Popular with local divers. Morning visits recommended for best conditions.
After heavy rain anywhere on Maui, stay out of the ocean for at least 72 hours at Kihei beaches. Wailea and Makena flush better but the same caution applies. Learn more about swimming after rain in Hawaii.
