When to Travel to Indonesia
The dry season starts in April and lasts until October, which is the best time to travel, though monsoon season, from November and March is fine to travel as well. It’s quieter than in the high season and the rain is generally limited to a couple of hours at the end of the day. On most of the islands there’s little difference between the winter and summer, with temperatures averaging 25C-30C all year round.
When to travel to Sumatra and Java
The rainy season on Sumatra and Java lasts from November – March with most of the rain falling in the late afternoon. In the West and South-West you can expect the occasional spot of rain in the dry season as well. On Sumatra the monsoons can very heavy making roads inaccessible, whereas in eastern Java there’s hardly any rain in dry season. Temperatures average 22-29 degrees all year round. Best time to travel to Sumatra and/or Java is May – September.
When to travel to Bali
Dry season lasts from April – September, with May, June and July being the coolest months when temperatures ‘drop’ to 28C. Monsoon season starts in October and ends in March, but in between the monsoon showers you can expect bright blue skies and plenty of sunshine. That’s why the monsoon season is fine to travel to Bali. The hottest months are February and March, with temperatures around 30C. Best time to travel to Bali is in the drier, cooler months from May – August, with high temperatures during the day and cooler evenings with a refreshing sea breeze.
When to travel to Nusa Tenggara (Lombok, Flores, Gilis)
The difference between the dry and wet season is slightly bigger in the Nusa Tanggara region, which lie to the east of Bali. The driest months are August and September, the wettest are November – February. The duration of the dry and wet seasons vary per island though. The climate on Lombok is similar to Bali, and the same goes for Sumbawa and Flores. As a rule of thumb: the closer to Australia, the longer the dry season.
When to travel to Sulawesi
Due to its irregular shape and the fact that it’s on a geographical borderline, Sulawesi has two opposite climates. The South-West also has a monsoon season from October – March. In the North, around Manado, most of the rain falls in June and July, but has a dry season from August – October. Temperatures can vary significantly; along the coast it can be (stiflingly) hot with temperatures around 34C, whereas the hills can be cool with a maximum around 24C, cool enough to need a sweater in the evening.
When to travel to Kalimantan
While it rains throughout the year in Kalimantan the “dry season” is in July – September, and it is the best time to travel in this area. January and February have the most rainfall, but there is still a mixture of sun and rain. Although you will have to contend with hot afternoons and lots of honey bees, in the dry season the forest creatures are at their loudest, leaches are few, trails are dry, and butterflies are plentiful. The second-best time to visit Kalimantan is November-December when ripe fruit and wild boar are in abundance. November also tends to be dry and is honey harvesting season.
