Climate and Average Weather in Indonesia

In Indonesia, nearly all the major islands experience a tropical rainforest climate. Meanwhile, the smaller islands to the east of Java, as well as some parts of Java itself, experience a tropical monsoon climate. Daytime temperatures in most of Indonesia hover around 30°C throughout the year. However, cooler temperatures can be found in elevated areas, particularly in Papua, where the highest peaks might even see perpetual snow.

Generally, visitors can expect tropical weather conditions, where bright sunshine intermingles with occasional heavy rain and thunderstorms. The monsoon season spans from September/October until the start of April, during which both the frequency and intensity of rainfall increase. By the end of the monsoon, humidity levels typically hover just above 80 percent, making the environment feel especially warm and sticky.

Come April, the dry season starts across most of Indonesia. Yet, during this drier phase, the northern regions still encounter brief rainfall in June and July. August and September are notably drier, especially in the southern parts. By October, rainfall begins to pick up once more.

Wondering when's the best time to visit Indonesia? June to September stands out as a great period. This span is the driest and sunniest for a significant portion of Indonesia, and temperatures are somewhat cooler. Specifically, August and September are ideal for sun-seekers planning a trip to Indonesia. While July is also favorable, it's marginally wetter. Similarly, June is a suitable alternative for those looking to sidestep the peak tourist season.
