Brunei Darussalam, the Abode of Peace, is a small but wealthy sultanate on the island of Borneo. This pristine nation offers a unique blend of opulent Islamic architecture, pristine rainforests, and traditional water villages alongside modern luxury.
Brunei has a hot and humid equatorial climate with temperatures averaging 26-32°C year-round and no true seasons. Annual rainfall is very high at 2,500-3,000mm, falling throughout the year with two notable wetter periods: the northeast monsoon (October-January) and a secondary wet spell (May-July). Despite high rainfall, sunny periods are common year-round and rarely does it rain all day. Humidity is consistently high at 70-90% making the heat feel more intense.
