What Time Of The Year Is The Best To Visit Borneo? Travellers and tourists are able to visit Borneo throughout the year, yet this country has 2 extremely distinct seasons. The dry season runs from March through to August, and then a wet season that runs from September through to February. Rainfall is usually sporadic during the wet seasons, with some of the weeks not experiencing any rain, while others are completely drenched. This represents the opportunity to plan your trip to Borneo with fewer tourists, much smaller crowds, and even the potential for good weather even though it is a wetter season. The temperature is also affected by altitude, while higher elevation regions are much cooler compared to the coastline. However, the entire region experiences consistent temperatures throughout the year which ranges between 80F to 90F in lowlands and 65F to 75F in mountain areas.
