Java

With its endless green rice paddies, rumbling volcanoes, fascinating culture and spiritual temples, Java is one of the most captivating islands in Indonesia. Its rainy season lasts from November to March, with most of the rain falling in the late afternoon. Java remains mostly dry in the dry season and temperatures usually remain hot pretty much all year round. The best time to travel here is between April and October.

Sumatra

If you fancy embarking on a real adventure holiday, Sumatra is the ultimate destination in Indonesia. Similarly to Java, Sumatra’s rainy season begins in November and ends in March. The monsoons here can be very heavy, making roads inaccessible and in the west and south west you can also expect the occasional spot of rain in the dry season too. The best time to travel to Sumatra is between April  and October.

Bali

Whether you’re tempted by its wild beaches, its lush plains of luminous rice paddies or its wondrous temples, you’ll find that Bali is home to an array of sights which are sure to delight! The dry season here lasts from April to September and the monsoon starts in October and ends in March.

Nusa Tenggara

Nusa Tenggara is a tropical wonderland of dazzling white beaches, luminous turquoise seas, hidden villages and thrilling wildlife. If you want to explore this area during your travels, its worth knowing that the difference between the dry and wet season is slightly bigger in this region, which lies to the east of Bali. The driest months are August and September and the wettest are November to February, however the duration of the dry and wet seasons vary per island. As a rule of thumb, the closer to Australia you are, the longer the dry season lasts.
