Borneo Weather

Borneo, like most of Southeast Asia, has an equatorial climate which is typically hot and humid throughout the year. Rainfall is high, exceeding 4000 mm annually in certain areas. Temperatures rarely exceed 32°C (90°F) and in coastal areas where most of the cities are located; it rarely drops below 20°C (68°F) at night. However, townships located on higher altitudes have much lower temperatures. Relative humidity is 85-95 per cent.

Between November till January, the North East Monsoon season begins, bringing heavy rain to the shores of Sabah and Sarawak in the Northern part of Borneo. March till September are generally the driest months due to the South West Monsoon bringing dry winds. Still, there is no sharp distinction between the two seasons and you do get occasional heavy rains in dry seasons and vice versa. For the most part, Borneo’s weather is perfect for a visit throughout the year.
