Indonesia weather & when to go: February

NB: the westernmost point of Indonesia is a full 3200 miles from the eastern most tip, so it should come as no surprise that summarising the weather is not straightforward. The tables above split the ‘country’ (made up of 17,508 islands) into two regions - the western & central islands and the eastern islands (that sit to the east of the Wallace Line), however we encourage you to read the more detailed summaries below as there can be significant variations in conditions between the islands within each group.

Java

The rainy season continues throughout February across the island of Java, although Surabaya and East Java experience slightly less rainfall than West Java and Jakarta, which is still prone to flooding at this time. Despite overcast skies average temperatures remain around 27°C. The mountains of Bromo and Ijen are still best avoided during February.

Bali

Rainy season continues on the island of Bali in February. Expect warm, humid days punctuated with intense downpours and average temperatures of 26°C. Rough seas at this time make for poor diving and snorkelling conditions around Menjangan and the West Bali National Park. 

Nusa Tenggara

Lombok, Flores, Komodo National Park, Sumba

February’s weather conditions are similar to January on Lombok & the Gili Islands, Flores & Sumba. Rain should still be expected on a regular basis however, rain showers are not as heavy or as frequent as those experienced in February on the island of Bali. Temperatures average around 28°C. Sumba's unique Pasola festival, that takes place in February, is reason enough to visit in one of the region’s wetter months. 

Sumatra

North Sumatra's average rainfall drops off considerably in February, making this a tempting month to visit if you are keen to avoid peak crowds, although some rain should still be expected particularly in the jungles of Bukit Lawang. The drier weather also means a higher chance of spotting orang-utan around Bukit Luwang. The wet season continues in South Sumatra and comes in the form of intense downpours which can impact road conditions. Average temperatures hover in the region of 27°C and humidity levels in Palembang and the south remain high.

Kalimantan

Kalimantan is transitioning between heavy rainy season and the lighter rains that fall up until May. If you're planning on visiting the rainforest and Tanjung Puting National Park during wet season you'll need to be extra patient when orang-utan spotting as they prefer to shelter from the rain. Keep your ears peeled for the sound of large movement in the trees and look out for ‘nests’ high in the forest canopy. Average temperatures remain around 26-27°C. 

Sulawesi

The monsoon continues in Toraja and southern Sulawesi, with Manado and north Sulawesi experiencing slightly less rain. Days are still warm and can be sunny (albeit with overcast skies), with average temperatures around 27°C and high humidity.

The Moluccas

Weather conditions across the Molucca islands during February are similar to conditions in January. The central islands of Ambon and Seram are enjoying the best weather in the region; whilst rainfall can be expected across the southern islands of Kei and Aru, and the northern islands of Ternate and Tidore. Boat transfers are frequently cancelled in the Banda Islands at the beginning of the month due to high winds and rainfall.

West Papua & Raja Ampat

February is an excellent time of year to visit the islands of Raja Ampat. Weather conditions are at their peak for diving during this month: the waters are calm, visibility is at its best, and there is a greater chance of spotting manta rays at the cleaning stations. Daily temperatures average 29-31°C. In Wamena and across the Baliem Valley weather conditions are similar to January: showers can be expected and average daily temperatures hover around 22°C.
