Open Water Diver (pool area) / Advanced Open Water (Azure Window remains and caves)

From May to October for visibility and calm sea conditions

15°C – 26°C at the surface / 14°C – 18°C at maximum depth.
Technical recommendations
The choice of wetsuit should reflect the season and the planned dive profile between the Blue Hole and the new external rock formations. During the summer months, a 5mm wetsuit is perfect for enjoying the warm surface waters, while the use of a semi-dry suit is highly recommended in spring and autumn when temperatures drop significantly below the first few meters. A dry suit remains the preferred choice for those intending to explore the remains of the Azure Window at greater depths or during winter. It is essential to bring an underwater torch to illuminate the cracks between the collapsed boulders and the inner chimney cave where natural light only partially penetrates. To maximize bottom time among the giant submerged rocks, the use of Nitrox is the best strategy, allowing divers to explore more calmly the complexity of the new natural artificial reef created by nature.
