Best time to visit

There is no good or bad season to visit Brunei. You are likely to encounter warm, humid weather and at least some precipitation whenever you come, so whether you're coming for the shopping, the rain forests or the beaches, it's a good idea to bring along lightweight rain gear.

Required clothing

Lightweight cottons and linens. Waterproofing is advisable all year.


Brunei is on the northern coast of Borneo, the world's third-largest island, just 443km (277 miles) north of the equator. All its land borders are with the Malaysian state of Sarawak, which splits Brunei into two parts. The landscape is mainly pristine equatorial jungle drained by small rivers. Most settlements are situated along estuaries. There are four districts: Brunei-Muara (the capital district), Tutong and Belait (the centre of oil and gas exploitation), in the western part of the country; and non-contiguous, heavily forested Temburong, in the east. The islands in Brunei Bay fall within the Brunei-Muara or Temburong districts.
