Borneo December weather overview

It’s tricky to avoid the wet weather across Borneo in December, making travel, trekking and wildlife spotting less than ideal. Temperatures remain high and occasionally the sun will break through the overcast skies.

December’s weather in detail

Sabah

Kota Kinabalu, Kinabalu NP, Kinabatangan River, Danum Valley, Sepilok, Gaya Island, Lankayan & Selingan Islands, Mabul & Sipadan Islands

As with neighbouring Sarawak, December is one of the wettest months of the year across Sabah; days are characterised by heavy rainfall and a high chance of thunderstorms. Much of the wildlife will be taking shelter from the rains, Mt Kinabalu’s paths will be muddy and slippy, and underwater visibility levels are not ideal for diving and snorkelling. Having said that, dry spells are not uncommon and comfortable temperatures and lower humidity levels make for good trekking, although be sure to pack waterproofs.

Avg daily temp: 27°C, avg monthly rainfall: 351mm.

Sarawak

Kuching, Damai Beach, Miri, Mulu National Park, Batang Ai

December is one of the wettest months of the year across Sarawak. Frequent thunderstorms and heavy rainfall can make travelling difficult to the more remote areas and conditions for jungle trekking and caving in Mulu National Park are far from ideal (infact some of the caves may not be accessible at this time).   

Avg daily temp: 26°C, avg monthly rainfall: 480mm.
