Diving here is available year-round, although there is some variation in water temperature: in summer months it’s about 30C/86F, whereas in January it drops down to 24C/75F. Also keep in mind that around April-May there is a plankton bloom that reduces visibility, and during late autumn and winter the Elphinstone Reef and certain other offshore dive sites can be unreachable due to weather conditions.
What to see
