Best for advanced divers, 30-45m, boat entry, strong current.
P-39 is a demanding site located 1500 metres offshore in the River Gurara Wreck Area. This site features a complex topography of reef, canyon, and drift environments at depths ranging from 30 to 45 metres, with an average depth of 36 metres. Due to strong currents, boat access is required, and dives must be timed precisely around slack water. Visibility is variable, ranging from 3 to 15 metres. Given the depth and current, this site is suitable only for advanced divers. Water temperatures remain between 15 and 16 degrees Celsius, making a drysuit or a 7mm wetsuit with a hood recommended for thermal protection.

Time your dive around slack water: the current here is strong enough to make the canyon undiveable outside a narrow tidal window, and your operator will know the right entry time. Water temperature sits at 15 to 16 degrees Celsius year-round, so a drysuit or a well-fitted 7mm wetsuit with hood is the practical choice.
