Brunei Darussalam is currently at the peak of the Southwest Monsoon period (August and September) where the weather conditions tend to be slightly hazy mainly originating from trans-boundary haze. Gusty showers are also expected at times due to the indirect tail-end effects of typhoon or tropical storm when it occurs over the South China Sea and the Western Pacific Ocean.

By October up until November, the country is expected to undergo the transitional (inter-monsoon) period where weather conditions are usually influenced by local wind effects that play a crucial role in the formation of localise thunderstorms. These thunderstorms are more likely to develop over the interior parts of the country during the afternoon and then spread across the coastal and sea areas at night.
Based on the current regional weather situation and the latest seasonal climate forecasts from the leading world climate centres, La Niña is slightly favoured to develop over the Pacific Ocean during August to October 2016, with 55-60 percentage chances of La Niña occurring during the end of 2016 and early 2017.

From previous events, the impact of a strong La Niña to Brunei Darussalam is a significant increased in rainfall amount that resulted in a number of flash floods due to the prolonged heavy rain. Since the likelihood of the phenomena occuring is still minimal, its impact to the weather patterns in our region in the coming months is also quite low. However, the amount of rainfall is predicted to be slightly higher than average during the end of this year (November and December 2016).

The BDMD shall keep monitoring the weather conditions, and will issue weather advisories or warnings as and when necessary. We would like to advise the public to keep updated with the latest weather information by visiting our website at or follow our Facebook (bruneiweather) and Brunei WX mobile application.

Wallahualam Bissawab.
