ONSET OF INTER-MONSOON SEASON FOR BRUNEI DARUSSALAM 26 MARCH 2020
28 Mar 2020
Brunei Darussalam has entered the inter-monsoon period and is expected to last until the end of May or early June.
The inter-monsoon period is a transitional period from the Northeast Monsoon to the Southwest Monsoon. During this
period, the absence of prevailing monsoonal wind flow has allowed diurnal wind effects to play an important role in
governing our daily weather. Based on our climatological records, the frequency of thunderstorms occurrences is high
during the inter-monsoon period with an average rain days for April is 17 days and May is 18 days.
Throughout this period, the country normally experiences:
1. Weather can be hot during the daytime;
2. Variable light winds during the morning and active development of thunderstorm clouds in the afternoon;
3. Thunderstorm mostly occurs over inland areas during the evening and propagating out to the coastal and sea
areas during late night to early morning.
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 up to date with the latest weather information by visiting our website at
