Indonesia climate: when to go to Indonesia

Indonesia has a type of climate profoundly influenced by its location along the equator and by the sea, this translates into a humid tropical climate that in the south-east becomes relatively drier. Temperatures are stable throughout the year, with minor variations, the average maximum temperature is around 32°C/28°C, while the average minimum temperatures are between 20°C and 24°C.

In much of the country we can identify two seasons based on rainfall which are regulated by the monsoon, in particular, there is a rainy season which extends generally in the months between October and April, and a dry season which includes the months between May and September.

In the vast majority of the Indonesian archipelago fall on average between 1,800 mm and 3,200 mm of rain per year.

The mountainous areas of the larger islands such as the western areas of Sumatra, Java, New Guinea, Borneo and Sulawesi are the wettest areas of the country, in some areas it may exceed 6,000 mm of rain per year. In these areas the dry season disappears almost completely, limiting itself to only a slight reduction in the amount of rain during a few months.

The islands closest to Australia, including the Lesser Sunda Islands to the east of Bali, tend to be more dry, with some areas on the islands of Sumba and Timor, receiving less than 1,000 mm of precipitation per year. Here, the dry season is more pronounced and extends to the months between May and November.


The best time for a trip to Indonesia, in relation to rainfall, is the driest period from May to September.
