The climate of Indonesia: when to go to Indonesia

The climate of Indonesia is profoundly influenced by its location along the Equator line and the presence of the sea. This results in a humid tropical climate that becomes relatively drier towards the south-east. Temperatures are stable throughout the year, with minimal variations. The average maximum temperatures are around 32 ° C / 28 ° C, while the average minimum temperatures remain between 20 ° C and 24 ° C.

In most of the country two seasons can be identified based on the rainfall that is regulated by the monsoon. In particular, in the islands of the Indonesian archipelago there is a rainy season that generally extends in the months between October and April, and a dry season that includes the months between May and September.

n the vast majority of the islands of the Indonesian archipelago, the rains are very abundant, generally on most of the archipelago they 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 rainiest areas of the country. In some areas, it can exceed 6,000 mm of rain per year. In these areas the dry season disappears almost completely, limiting itself only to a slight reduction in the amount of rain during a few months.

The islands closest to Australia, including the Sunda islands east of Bali, tend to be drier. There are some areas in the islands of Sumba and Timor that receive less than 1,000 mm of rainfall per year. Here the dry season is more pronounced and extends to the months between May and November.
