Based on the monsoon cycle, Brunei Darussalam is expected to experience the Northeast Monsoon from December 2018 until March 2019. Normally during the rainy season in December and January, the country will experience very active weather conditions with occasional heavy showers and thundershowers especially during the afternoon and at night. Whereas during the stable period in February and March, lesser rainfall is expected.

Referring back to previous Northeast Monsoon events, it is important to note that the risks of flash floods and flooding at low-lying and flood-prone areas, and the risks of landslides, can occur especially during heavy rainfall of more than 2 hours. The risk of severe flooding may occur during the event of heavy rain coinciding with high tide. Strong surges from the Northeasterly winds may also increase the wave height over Brunei Waters from moderate to rough states.

In this regard, the general public are advised to take necessary measures and precautionary actions especially during the upcoming rainy season, and to always be alert with the latest weather warnings or advisory issued by the department in order to ensure safety and preventing undesirable incidents.

We shall continue to monitor the weather conditions and will issue weather advisory or warnings if necessary. We would also like to advise the public to keep updated with the latest weather information by visiting our website at website at or follow our Facebook (@bruneiweather), Instagram (@bruneiweather) and Brunei WX mobile application.
