The diving on the west side of the atoll in the southwest season is spectacular. You will regularly encounter large schools of pelagic fish like sharks, eagle rays and tuna.

Another noticeable feature of the southwest season is that the water temperature is usually one or two degrees lower that the usual 28º C (82ºF). This has an effect on both the behaviour and sightings of marine life, particularly the grey reef sharks and hammerheads , which seem to congregate in larger numbers and in shallower water at this time of year.

On the eastern side of the atolls, the southwest season is the best time to see manta rays and whale sharks. Here your visibility is not so good, but this is compensated for by the wonderful experience of diving with these huge plankton feeders.
