Brunei Darussalam will be entering the Northeast Monsoon towards the end of November 2019 and is expected to persist until March 2020. The first two months of Northeast Monsoon (December and January), also known as the rainy season, normally have the highest amount of rainfall as compared to the other months. During this period, unsettled weather conditions with occasional heavy showers or thundershowers are expected especially during the night and early morning. Whereas during the second half of Northeast Monsoon (February and March), the atmospheric conditions tend to be more stable with
lesser rainfall.

During the rainy season, it is important for the general public to note that the risk of flooding or flash floods at low-lying and flood prone areas, and the risk of landslides will be high especially when heavy rainfall occurs for more than 2 hours. The risk of severe flooding may occur during the event of very heavy rain coinciding with high tide. Strong surges from the Northeasterly wind may also result in the increase of wave height over Brunei waters to rough state.

In light of this, members of the general public road users and fishermen are advised to always be up to date with the latest weather forecast, advisory and warning issued by Brunei Darussalam Meteorological Department, and to take precaution and any necessary actions to ensure safety and to prevent any undesirable incidents.

We will continue to monitor the weather conditions from time to time, and will issue weather advisory or warnings if necessary. The latest weather information can be obtained by visiting our website at or follow our Facebook (@bruneiweather), Instagram (@bruneiweather) and Brunei WX mobile application. The public may contact Duty Meteorological Forecaster at our Forecast Centre, through our Weather Line 114.

Wallahu a'lam Bissawab.
