Key Dive Site Facts
Dive Site Overview
Keawakapu South offers a compelling shore diving experience, serving as a gateway to both natural reef structures and an extensive artificial reef. Your dive typically begins from the beach, involving navigation toward a system of submerged concrete forms, tire structures, and a wreck.
Many divers utilize scooters here; these tools facilitate efficient transit to the St. Anthony wreck and the distinct Z-blocks system. This artificial reef's history traces back to 1962 with old automobiles, which eventually degraded, prompting further ecological intervention. Subsequent efforts introduced robust concrete forms embedded with tires, effectively creating tubular caves and a more stable foundation for coral growth and marine habitation.
By 1997, the 65-foot longliner St. Anthony was purposefully sunk, becoming South Maui's most recent and significant artificial reef addition. Maximum depth at the St. Anthony wreck and surrounding pinnacles is approximately 26 m (85 ft).
Continuous development has transformed this entire site into a thriving habitat, now supporting over 60 species of fish and offering varied terrain for exploration.
Best Time to Dive
Planning your dive at Keawakapu South with an eye on conditions is key for optimal visibility and comfort. The months from May through October often present more favorable surface conditions, with average air temperatures ranging from 23.9-25.7°C (75-78°F) and minimal rainfall, frequently below 1 mm (0.04 in). During these periods, average wave heights typically remain under 1 meter (3.3 ft), contributing to calmer entries and improved underwater clarity. While specific water temperatures aren't consistently reported for this site, the air temperatures suggest pleasant overall conditions. Even in other months, such as March and November, the dive score remains high, indicating generally good diving. Lower wind speeds, often around 14-15 km/h (9-10 mph) in the autumn, can also contribute to smoother surface conditions.
