The best time to visit Borneo is between March and October, when the island is hot, humid, and at its driest. This makes it one of Southeast Asia’s few summer destinations. It is also 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, 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 traveling during May-June or September-October to avoid the peak season hotel charges and crowds. These are great times to see wildlife without too many other people around and the weather is favorable if you wish to combine your trip with some time on a beach.

Month-by-month guide to traveling in Borneo

En route to Mataking Island, Borneo

Visiting Borneo in October

October is a great month to catch the last of the good weather prior to the rains setting in. Shoulder season prices take effect, and orangutans can still be seen in the wild. This is also the prime time for diving at Sipadan.

Events & Festivals

  • Deepavali/Diwali (October): The Hindu 'Festival of Lights' is celebrated throughout Borneo as families gather to pray and give gifts.
