In Sabah, we would recommend the northern parts in February, including Kota Kinabalu and the northern coast, with island resorts such as Gaya Island and Lankayan Island warm and relatively dry. This means you can experience some of Borneo’s amazing wildlife and beautiful beaches in relative isolation. The southern parts, including the Danum Valley and Sipidan Islands are still likely to have heavy rain, as are the coastal and inland areas of Sarawak. Sarawak can be travelled, but we would only recommend this to those unaffected by the weather and not looking for a sunny holiday, as the average monthly rainfall is still high at about 520mm.
