Diving is possible all year round but is governed by an island's position and the prevailing winds. Generally speaking, the best conditions for both the Inner and Outer Islands are in the calm periods, April-May and October-November, when the water temperature can rise to 29ºC and offers excellent (up to 30 metres) visibility.
In December and January, the north-west winds blow but conditions remain much the same as in the calm periods, with the exception of greater surface movement and some localised turbidity.
From May to September the winds are stronger and blow south-easterly. Visibility and temperature may thus drop during August with water temperatures of around 25°C. A wet suit of at least 4mm is necessary.
Unlike the Inner Islands, some of the more southerly Outer Islands are close to the cyclone belt, and during these months they can experience extremely rough conditions on occasion.
A 4mm shorty wetsuit is the minimum protection recommended for the Outer Islands. Islands with big drop-offs and walls often have marked thermo-clines with temperatures ranging from 19 to 27ºC and a full suit is an advantage for most divers.
