Frequently asked

When is Indonesia's rainy season?

Most of Indonesia is wet November to March. The peak is January and February. Raja Ampat and eastern Indonesia have an inverted season — their best months are October–April.

Can I still travel in the wet season?

Yes. Most days have a clear morning + heavy afternoon storm + clear evening. Hotels are 25–50% cheaper, crowds drop, and rice paddies are at their greenest. Skip volcanic treks, fast-boat-dependent outer islands, and tight onward flight connections.

Which Indonesian region is driest year-round?

Komodo / Flores has the most reliable dry season (May–November) and shorter, milder wet season than Bali. Raja Ampat is the opposite — driest October–April.
