Climate in East-Indonesia, the Moluccas & East of Wallace

Weather and Climate in East Indonesia, East of the Wallace Line

Located on both sides of the equator, Indonesia has a tropical climate with year-round warm temperatures. Due to the wide extent of the island state, the seaons or, more precisely, the length and extent of rainy and dry season is not the same in all parts of the country. For example, the climate of the southern region between East Java and the small Sunda Islands and further on to the Aru Archipelago is strongly influenced by the monsoon and thus has significantly more pronounced dry and rainy seasons than other parts of the country.

On the northern islands such as Sulawesi and the Moluccas, in contrast, there is a humid tropical climate with barely fluctuating temperatures throughout the year. The thermometer in coastal areas, for example, consistently shows average daytime temperatures around and above 30° C, dropping to 21-24°C at night. And while in the lowlands a very high humidity, combined with prevailing calm weather, creates a sultry climate, in the higher altitudes and in the mountains, it remains quite pleasant at around 15-25°C.
