    “Feels-Like” Temperatures

    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.

    Precipitation (Rain or Snow)

    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. The best time to ski (if at all) in Indonesia is often around around July 23rd when fresh powder is deepest. 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.

    Overall Indonesia Travel Experience by Season

    Fall (March through May)

    Humidity and temperatures combine to make this season feel warm. Highs range from 88.9°F (31.6°C) and 87.9°F (31.1°C) with similar temperatures in the later months. Rain is somewhat common with 6 to 8 days of significant precipitation per month. Fall is the second busiest for tourism, which makes it a good time for those looking for things to do.

    The middle-year months have very comfortable weather with high temperatures that are quite warm. These months see the least precipitation with 4 to 6 days of precipitation per month. June – August is the busiest season for tourism in Indonesia, so lodging and other accommodations may cost more than usual.

    Spring (September through November)

    Spring daily highs range from 89.8°F (32.1°C) and 88.2°F (31.2°C), which will feel very nice given the humidity and wind. It rains or snows a significant amount: 4 to 8 days per month. Tourism is the slowest during these months due to the weather, so hotels may be affordably priced.

    Summer (December through February)

    Weather is perfect this time of year in Indonesia to be enjoyable for warm weather travelers. The average high during this season is between 88.3°F (31.3°C) and 87.2°F (30.7°C).
