When is the best time to scuba dive in Indonesia?

Choosing when and where to dive in Indonesia shouldn't be difficult. Most Indonesia dive liveaboards will choose for you!

Best time to dive in Indonesia?

Don’t worry though! We have made it easy to plan your travels because our Indonesia scuba diving liveaboards spend the best seasons in the best locations. This roughly works out to Raja Ampat from November to April and Komodo from May to October, getting the best diving and avoiding the rainy seasons in both. We reposition the boats during April and October and have planned trips to the Banda Sea and the Forgotten Islands those months.

Indonesia enjoys a tropical climate year-round and its seasons generally fall into wet season or dry season. But here’s the catch – Indonesia is a huge country (the world’s largest island country to be specific) and is made up of over 17,000 islands that span over a massive area between the Indian and Pacific oceans. This means one area’s wet season is the dry season in another area, even though it’s the same country.

This is perfect for us because Komodo and Raja Ampat have opposite seasons and we just move the boats to where the weather is likely to be best. We dive Komodo May-October during its dry season and Raja Ampat November-April in its dry season. However, keep in mind, it does still rain during the dry season, but overall wind and storm conditions are likely to be better then. Rain can always fall and a few rain drops won’t ruin your diving (they keep the islands lush and green and give us rainbows!) (Pro Photo tip – if visibly is bad because of bad weather, shoot macro photography, the little critters in Indonesia are really cool!

We dive the Banda Sea and the Forgotten Islands in October and April while we reposition the boat and the weather is generally good in that location during those months too.
