In Wakatobi you can enjoy diving 365 days a year. There is no period or season unsuitable for diving, and we have skipped only 4 dives in the last 10 years. The climate is drier than in other parts of Indonesia, and the location is nicely protected by the surrounding reefs and islands.
Generally speaking we have two seasons: Easterly winds from June to October, and Westerly winds between December and April. November and May are usually transitional months. July and August see a slight increase in wind, and the sea ripples somewhat; visibility is still fine. The weather in these months is a little cooler than the months on either side, making it a great time to visit for those who prefer to sleep without using an air-conditioner at night. (book an Ocean Bungalow on the South beach to enjoy the breeze).
