The best time to go to Sumatra
You can see orangutans all year round in Sumatra, but it’s much easier if you skip the annual monsoon season.
Sumatra has a hot and humid tropical climate, with average temperatures sitting at 27-28°C throughout the year. The seasons can be broadly divided into dry and wet. Monsoons between November and March often lead to potholed and unpaved roads becoming inaccessible, while hiking can be miserable during a downpour. The best time to visit Sumatra is either between May and June, or September and October, missing the peak (and hottest) summer months when it can hit 34°C. Medan, and other parts of northern Sumatra, can get rain throughout the year. Orangutans can be seen at any time, but when the trees are in fruit in the autumn months they tend to stick to the forests and so appearances at feeding stations are less regular.

More about Sumatra
Our Sumatra travel guide draws back the veil on an island of mystery, rare wildlife, smouldering volcanoes and colourful tribal culture.
For most visitors to Sumatra, one of their first ports of call is likely to be Bukit Lawang, gateway to Gunung Leuser National Park, which is among the most diverse ecosystems on the planet.
