The diving conditions vary with the seasons. The dry season, December to May, offers the best visibility and calmer, warmer water. During the rainy season, June to December, the water contains more nutrients that reduce the visibility, as do thermo clines, but the pelagic life is better. The average water temperature hovers around 28°C. Visibility is on average around 70ft/19m. Thermo clines and haloclines are common and can reduce the water temperature as much as 10 degrees and the visibility by 20 to 30ft on deeper dives. Tides predominate the diving conditions in the CNP with as much as a 16ft/5m tidal exchange every six hours, consequently currents are common and vary in direction and speed. This is adventure diving at its best. Many of the areas in the park still remain unexplored. Forget about crowded dive sites and boats. This still remains to the most part an undiscovered wilderness!
