Bandar Seri Begawan experiences a tropical equatorial climate with high temperatures and humidity year-round, sitting just north of the equator where seasonal variation is minimal.

Rainfall occurs throughout the year, though the northeast monsoon brings heavier downpours from November to March, making waterproof layers more essential than warm ones.

Temperatures hover consistently between 24°C and 32°C, with little variation between months and practically no chance of experiencing anything resembling cold.

Humidity regularly exceeds 80%, creating that perpetual sticky feeling where even standing still feels like light exercise.

Footwear that dries quickly is particularly valuable here, as the combination of sudden tropical downpours and waterlogged footpaths can leave leather shoes sodden for days.
