Climate and Average Weather in Indonesia

In Indonesia almost all major islands have a tropical rain forest climate. The smaller islands east of Java and some parts of Java itself have a tropical monsoon climate. During the day, temperatures in most parts of Indonesia are around 30 degrees Celsius (86 degrees Fahrenheit) or slightly higher throughout the year. It is cooler in the higher areas and especially in Papua with the highest peaks which can even be covered in eternal snow.

In general you will almost always experience tropical weather conditions where a bright sun is mixed with sometimes heavy rain and thunderstorms. During the monsoon period that runs from September/October to the beginning of April, the number of precipitation days increases just like the intensity of the rain. At the end of the monsoon, humidity has reasonably high rates (just above 80 percent). Especially in that period, it feels very warm and sticky.

In April the dry season starts in almost all of Indonesia. During the drier period, the north of Indonesia still faces a small rain period in the months of June and July. August and September are considerably drier, especially in the south. In October the amount of precipitation increases again.

What is the best time to visit Indonesia? The period June to September is the best time to visit. This is the drier and sunniest period in a fairly large part of Indonesia, also it is bit cooler. The months August and September are the best period for a sun holiday to Indonesia. July is fine too, but a little wetter. The same goes for June, which is a good alternative for those who want to avoid the expensive high season.
