Water Temperatures
Ocean water temperatures rarely vary beyond 27 – 30° C although thermoclines can sometimes be experienced at depths below 20 metres. During hot periods, water temperatures inside the lagoons increases measurably, influencing water temperatures inside the atolls. During these periods most divers are comfortable diving without a wetsuit, 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.
