Sabah

Kota Kinabalu, Kinabalu NP, Sepilok, Lankayan & Selingan Islands Danum Valley, Mabul & Sipadan Islands

The north-east monsoon winds continue to blow from North-East Asia, but bring drier weather in February with a marked reduction in average rainfall from the previous month. The north coastal and central regions of Sabah are experiencing relatively dry weather, however heavy rain is still likely in southern and coastal regions including Danum Valley and the diving haven of Sipadan and Mabul Islands.

Sarawak

Kuching, Damai Beach, Mulu National Park, Batang Ai

Both the coastal and inland areas of Sarawak are still receiving high levels of fairly persistent rainfall during February. However, for hardy travellers, there are many benefits of lower visitor-numbers to be enjoyed in February and the National Parks, wildlife sanctuaries, jungle lodges and caves may be far more appealing without the hordes.
