If dry weather is what you’re after, the months with the lowest chance of significant precipitation in Indonesia are September, August, and then July.

By contrast, it’s most likely to rain or snow in mid December with an average of 2 days of significant precipitation the week of December 17th.
When can you find snow in Indonesia? Weather stations report very large amounts of snow likely to be deepest around July, especially close to late July.
