The year at a glance
Indonesia straddles the equator, so it is warm all year and splits into a dry season and a wet one rather than four seasons. These ratings follow Bali, where the dry months from April to October bring the sunniest, calmest weather and the peak crowds.
The wet season from November to March is hot and humid with heavy afternoon rain, but the storms often pass quickly, prices fall and the rice terraces are at their greenest. Diving and surfing both favour the dry months.

Komodo and the east
Drier and sunnier than the west. The dry season brings the calmest seas for diving and island hopping.
Best time to visit Indonesia for
Diving and snorkelling
April to October for the clearest water and calmest seas around Bali, Komodo and Raja Ampat.
Surfing
