Very Active Weather Conditions

Based on current regional weather situation and latest seasonal forecasts from the leading world climate centres, La-Nina conditions have been observed over the Pacific Ocean, and are slightly favoured (55% chance) to persist through February 2017.

This phenomenon is associated with the enhancement of rainfall over the Southeast Asian region, including Brunei Darussalam. However, the total amount of rainfall for December 2016 to January 2017 is forecasted to be normal.

The onset of Northeast Monsoon is expected over Brunei Darussalam by mid December 2016 until March 2017. For the first half of the monsoon season (December-January), the country will normally experience very active weather conditions with heavy and prolonged rain and thunderstorms, especially during the night and early morning. From local climate records, the months of December and January are known to have the highest amount of rainfall comparison to the other months of the year. In the light of this, the general public, road users and mariners, are advised to always be alert and to take necessary precautionary actions to ensure safety, especially during heavy rains and thunderstorms. It is important to note that risks of flash floods and flooding at low-lying and flood-prone areas, and landslides can occur, especially during moderate to heavy rainfall of more than 2 hours. Risk of severe flash flooding may occur when prolonged heavy downpour coincides with heavy high tide. Strong surges from the North-easterly winds may also result in the increase of wave height over Brunei Waters to Rough State (above 2.0 m).

The Meteorological department shall keep monitoring the weather conditions, and will issue weather advisories or warnings as when necessary. The public should keep themselves updated with the latest weather information by visiting the department's website at or follow its Facebook (bruneiweather) and Brunei WX mobile application. The public may also contact Duty Meteorological Forecaster at the Forecast Office, through Weather Line 114.
