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 travelling 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 favourable if you wish to combine your trip with some time on a beach.

Month-by-month guide to travelling in Borneo

Turtle, Sipadan-Mabul, Malaysian Borneo

Visiting Borneo in June

Hot, dry weather is present across most of Borneo in June, with the occasional rain shower occuring on Borneo's northern coastline. June marks the start of turtle season off Lankayan Island, while the fruiting season is in full swing in the forest, causing orangutans to venture closer as they forage. All of this makes June an extremely attractive time to visit.

Events & Festivals

  • Gawai Dayak/Harvest Festival (31st May - 1st June): An annual festival celebrated by the Dayak people in Sarawak, where it's a public holiday. It's marked with the sharing of food, decorated longhouses and traditional dress.
  • The King's Birthday (first Saturday in June): A national holiday marking the birth of Yang di-Pertuan Agong, Malaysia's head of state.
