Bahamas
Scuba Diving in The Bahamas is superb. I've dived all over the world and love coming back to The Bahamas. Marine life is plenty and varied - you can see various species of sharks, macro life, reefs, shipwrecks, blue holes and deep wall dives all in a space of 1 day! The water is warm all year round (although the winter months you will need a 3mm wet suit at a minimum). Summer months the water is generally flat with little waves but winter months the waves can be choppy - especially if there is a cold front coming through. Nevertheless, the water clarity is very good most of the time (100ft+ visibility).
