Brunei Darussalam Monsoon Situation

Brunei Darussalam is currently towards the end of Southwest Monsoon period, where southwesterly wind surge is still dominant with stable atmospheric conditions.

However, our weather conditions for the last few days were active due to the indirect influence of typhoon systems affecting areas over the Northwest of the Pacific Ocean.

Brunei Darussalam Weather Situation

Active weather conditions are forecasted to occur this week especially on the 22nd and 23rd September due to an active development of rain clouds and potentially causing occasional squally showers over our country.

Squally showers are expected to affect the country occasionally, especially over the sea areas and are likely to spread to the land areas. Wind speed may increase up to 50 km/h.

Over Brunei waters, sea state is generally slight, between 0.4 m to 1.0 m.

There is risk of flash floods especially at low-lying and flood prone areas as well as near the river banks during continuous heavy rain and also during high tide.
