Water conditions in August

Water temperature in Indonesia typically ranges 26-30°C. Visibility at Komodo National Park in August is generally good; check local liveaboard or dive operator reports the week of your trip for specific conditions. Drift, muck, pelagic is the primary dive style in Indonesia.
