Everything you need to know about this dive site.
Dive Site Overview
Venturing into Sterna reveals a captivating underwater landscape defined by its prominent wall formations. Divers exploring vertical contours will find the seafloor descends dramatically, plunging from shallower points into significant depths.
A classic wall dive, it invites thorough exploration of its various nooks, crevices, and ledges, often extending to 30 m (100 ft) or more. Good visibility typically provides a broad perspective of expansive underwater features, although specific conditions can vary. Moving along the wall's face, divers might observe subtle shifts in current, which are usually mild, enhancing the exploratory nature of the dive.
While consistent marine life reports for Sterna itself are limited, broader regional data suggests a potential for encounters with diverse species. Every descent offers an opportunity for discovery, contingent on prevailing conditions and seasonal patterns; you never know what the blue might reveal.
Planning a dive here means preparing for a dynamic deep wall exploration, with emphasis on buoyancy control and thoughtful depth management to fully appreciate the site's impressive structure.

Best Time to Dive
While Sterna consistently offers excellent diving conditions year-round, distinct seasonal characteristics shape the experience. The peak summer months of July and August provide the warmest average air temperatures, soaring around 31°C (88°F) and 29°C (84°F) respectively, coupled with minimal rainfall, averaging 0.07-0.12 mm. This creates comfortable surface intervals and generally calmer conditions with wave heights typically under 0.2 meters. Conversely, cooler months, from December through February, see air temperatures drop to 11.5-13°C (53-55°F), with slightly higher, though still moderate, rainfall figures up to 3.29 mm. These periods still maintain an 'Excellent' dive score due to calm winds and manageable wave conditions, simply requiring thicker exposure protection.

Dive Experience & Conditions
As divers begin their descent at Sterna, they'll encounter a prominent wall formation that plunges into deeper sections. The underwater topography creates diverse microhabitats along its face. Water temperatures are not consistently reported for this specific site, but based on regional trends and air temperatures, divers can generally expect a range of 22-27°C (72-81°F) during warmer months, cooling during the winter. Calm conditions are frequent, with average wave heights consistently low, often less than 0.2 meters, minimizing surface chop. Currents tend to be mild, but checking local conditions before entering the water is always prudent. The dive experience focuses on tracing the wall's features, observing the life clinging to its surfaces and exploring its contours.
Dive Difficulty & Safety Guidelines
Navigating Sterna's underwater environment requires adherence to standard safety protocols, particularly given its characteristics as a wall dive. Divers should always plan their depth and bottom time carefully, paying close attention to no-decompression limits and gas management. While no specific hazards are reported for Sterna, all wall dives inherently carry the risk of disorientation or rapid depth changes if not properly managed. Consulting local dive professionals familiar with the site's present conditions is highly recommended before any dive. Always dive within your certification limits and consider additional training, such as deep diving or specialty courses, if exploring the site's deeper reaches.
