Indonesia is a tropical country with a climate that is fairly even all year round. Influenced by the East and West Monsoons, there are two distinct seasons, ‘wet’ and ‘dry’, which differ depending on which part of the country you are in. The easiest rule to follow is that diving is best when it’s drier.  For Komodo and the Banda Sea, May through October is the best time for diving. For Raja Ampat, Triton Bay and North Moluccas, the opposite is true, so November through as late as May. The transitional period between the two seasons alternates between gorgeous sun-filled days and occasional thunderstorms.
