Borneo is one of Southeast Asia’s few summer destinations, with the best time to travel being between March and October when the island is at its driest. This is the best time to see orangutans in the wild, while turtles can be seen on Lankayan Island between June and September. During the rest of the year, Borneo experiences a tropical climate and the rains come to water the forest below. It's hot and humid for most of the year, with temperatures averaging 27°C to 32°C and humidity usually at around 80%. However, there's always somewhere to break up the trip; trek up Mount Kinabablu to be rewarded by stunning views and a cooling breeze, or head to the beaches for some swimming and world class snorkeling.

We recommend travelling during May to avoid the peak season hotel charges, crowds and most extreme temperatures. This is a great time to see wildlife, including orangutans in the forests and turtles off Lankayan Island.

Month-by-month guide to travelling in Borneo

Kinabalu National Park, Malaysian Borneo

Visiting Borneo in January

During January, Borneo sees some of its highest rainfall for the year; particulary in Sarawak. Sabah will most likely receive less rain at this time, but storms and high winds can make sea travel and reaching the more rural areas difficult. The poor weather also means that much of the wildlife remains hidden from view as animals shelter in the dense forest.

Events & Festivals

  • Chinese New Year (date varies): Chinese New Year is celebrated throughout Borneo with the usual festivities of singing, dancing and merrymaking.
