Island Dancer is not a big boat. It isn't a big expansive impressive motor yacht like some of the other Aggressors or Dancers. However it has small groups and will allow you to dive the very best dive sites of Fiji. So too does Naia and The Fiji Siren. So at least by focussing on liveaboards you are guaranteeing yourself some awesome diving. There are some currents there but i haven't experienced anything too bad. Some nice drift dives where you can cover quite a lot of ground. No need to fight the current. Plenty of sharks and some gorgeous colourful reefs.
We also advise customers to add on, if they can, the shark diving at Pacific Harbour since that can be quite an experience, if the thought of feeding doesn't trouble you too much. Fiji has done a lot more to protect their shark populations than many other countries. Better they feed a few of them than kill them, I say. Sounds like you could have a few days in Pacific Harbour before making your way to Suva. That's a good plan in fact.
Below is what we say on this page about the
Fiji dive season
[h=2]Diving Season[/h] The dive season is all year round. The winter months of April to October represent the main season for scuba diving in Fiji in terms of diver numbers, although the visibility tends to peak between the months of July and December when the water is cooler (sometimes, although seldom as cool as 22°C). 25°C is a realistic expectation of water temperatures during this period. It can cool enough in this period to reduce plankton activity sufficiently for the visibility to rise to impressive distances, sometimes exceeding 50m.
November to April are in fact Fiji's summertime and when the seas are at their warmest - around 28 to 30°C. This is also rainy season and December to March carries a greater risk of cyclones. Run-off from Fiji's rivers can reduce the otherwise excellent visibility, particularly on dive sites off the coast of Viti Levu.
For comfort and protection, many choose to dive with a 5mm full length wetsuit during winter months from May to October, and a 3mm full length or shortie during summer months from November to April.
The transition months, where the seasons cross-over are often considered ideal times to visit. They are November, April and May. Things also vary from place to place within Fiji. Morning showers in the highlands of Viti Levu are quite common at any time of the year. Bligh Water's excellent visibility is seldom reduced significantly even during wet season. Plankton blooms, particularly in rainy season can attract larger creatures such as plankton-feeding whales and manta rays.
