Ocean water temperatures rarely vary beyond 27 to 30 Degree Celsius although thermo clines can sometimes be experienced t depths below 20 meters.  During hot periods, water temperatures inside the lagoon increases measurerablly, influencing water temperatures inside the Atolls. during these periods most divers are comfortable diving without a wet-suit, although those of slight build may shiver a little. During overcast periods with wind and rain squalls, it is wise to carry extra clothing on the boat after a dive. Lycra and 3mm wetsuits are popular in tropical waters but some divers prefer a 5mm suit if doing more than one dive a day.
