Best for expert divers, 20-35m, boat entry, strong current.
Turner Island is a challenging reef site located off San Carlos, Mexico, defined by strong currents that require expert-level buoyancy and navigation skills. Divers typically explore depths between 20 and 35 metres. Visibility is limited, ranging from 5 to 10 metres, necessitating careful planning. Water temperatures fluctuate significantly throughout the year, from 16C in the spring to 27C in late summer, with potential thermoclines. Access is strictly by boat, and divers must be self-sufficient. Due to the intensity of the currents, which can shift rapidly, maintaining close proximity to the boat during entry and exit is essential for safety.
