Borneo destination guide

Best time to visit Borneo

Borneo is a tropical paradise that attracts visitors all year-round. The weather is hot and humid for most of the year, with average temperatures of 27°C to 32°C and relative humidity of 80%. Borneo has two distinct seasons: the dry season, which starts from March to September; and the wet season, which lasts from October to February when the North-East monsoon hits the island. You can expect brilliant sunshine in the morning and rain in the afternoon which generally last a few minutes to hours. However, the weather is often unpredictable and you should expect high humidity and rain at any time of the year.
For wildlife enthusiasts:
Mar to September is the best time to see orangutans in the wild, June to September is the best time to see turtles on Lankayan Island, March to May is the best time to see whale sharks.

Visiting Borneo in January
Borneo sees some of its highest rainfall in January and there may be storms brought in by the North-East Monsoon. The rains are particularly heavy in Sarawak with the beaches receiving the most rainfall of the year, and making inland travel difficult. Sabah receives less rainfall compared to Sarawak and the temperature remains hot and humid. The chance of seeing wildlife is not as good, but with fewer people visiting, you can expect a much quieter time on safari and competitive rates for accommodation.

Visiting Borneo in February
February can be a good time to take advantage of low season offers to visit Kota Kinabalu and the northern coast of Sabah. Days are warm and relatively dry with average rainfalls of 150mm compared to 300mm in January. Average temperatures hover around 28C. The southern part of Sabah continues to have heavy rainfall, making travel to the Danum Valley difficult. As with all tropical islands, the weather is unpredictable and unexpected rainfall can occur at any time. In Sarawak, the rain eases off from the January deluge, but it is still a very wet time.

Visiting Borneo in March
March is an excellent month to travel to Borneo, especially Sabah. With the beginning of the dry season, the rains have decreased and with low visitor numbers, this is a wonderful time to take advantage of offers from a wide choice of popular accommodation. Generally, March is one of the driest months in Sabah and is excellent for the northern beaches such as Gaya Island, Lankayan Island and the beaches of Kota Kinabalu. For wildlife enthusiasts, March also sees the start of the whale shark season. For mountain climbers, March is a good month to consider climbing Mt Kinabalu. In Sarawak, rain begins to decrease with opportunities for trekking and cave exploration.

With some of the best weather conditions for trekking and wildlife safaris, this is the perfect season to combine a wildlife and beach holiday.

Visiting Borneo in May
May is the start of Borneo’s peak season. The dry weather and shoulder-season prices make this a perfect time to look forward to. Unexpected rainfall should still be expected as with all tropical climate Jungle trekking in Sabah are rewarding with excellent chances of spotting orangutans in the wild.

The start of October is relatively dry and enjoys lower prices and fewer visitors. There are still many opportunities for wildlife sightings and dry conditions for jungle trekking. More rainfall is to be expected towards the end of the month as the wet season returns. Sarawak receives higher rainfall, especially on the coastal beaches.

Visiting Borneo in November
Heavy rainfall and thunderstorms signal the return of the wet season in Borneo. The wet conditions make jungle trekking difficult but it is still possible to visit wildlife sanctuaries and the National Parks. For wildlife enthusiasts hoping to see orangutans in the wild, this may not be the best time.
