The way we experience weather isn’t all about temperature. Higher temperatures affect us much more at higher humidity, and colder temperatures feel piercing with high winds. Our perceived temperatures factor in humidity and wind chill to better represent how hot or cold the day feels to a person.

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. Note that we define “significant precipitation” as .1 inches or more in this section. The lowest chance of rain or snow occurs around late September. For example, on the week of September 24th there is 1 day of precipitation on average. 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.

Please note that a value of 0 for snow in the graph below may either mean there was no snow, or that snow is unreported.
