Brunei Darussalam has entered the inter-monsoon period which is the transition period after the Southwest Monsoon and before entering the Northeast Monsoon. The inter-monsoon period is expected to last until the end of November 2023.

During this period, the absence of prevailing monsoonal wind flow has allowed local wind effects to play an important role in governing our daily weather. Based on our climatological records, the frequency of thunderstorms occurrences is the highest during the inter-monsoon period in comparison to the other months. Whereas the average rain days for October is 21 days and for November is 22 days.

Throughout this period, the country normally experiences:
• Fair weather in the morning and isolated coastal showers occur around midday;
• Thunderstorms occur over the inland during the afternoon, spreading and affecting coastal and sea areas at night, and may persist to early morning of the following day;
• Light wind blows from variable directions in the morning and at night, and from Northwest in the afternoon; and
• Wave condition at sea is generally at slight state.

However, with the El Niño conditions that are currently observed, our country typically experience suppressed rainfall activity with increasing air temperature. Hotter and drier weather conditions are likely to happen during the peak of the El Niño event during end of the year 2023 to early 2024. Maximum daily temperatures may reach up to 34.0°C or more during the afternoon. Excessive Hot Weather (EHW) or commonly known as heatwave event in Brunei Darussalam also tends to occur during El Niño episodes.

We shall continue to monitor the weather conditions from time to time and will issue weather advisories or warnings if necessary. Latest weather information, advisories and warnings can be accessed easily through our mobile app, Brunei WX, as these weather information, advisories and warnings can be received immediately after they are issued.
