Brunei Darussalam has entered the inter-monsoon period and is expected to continue 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 a role in governing our daily weather.

Throughout this period, the country normally experiences variable light winds during the morning and convective activities during the afternoon resulting in active development of thunderstorm clouds. Weather can be hot during the daytime while thunderstorm occurrences are likely at the inland area during the evening and propagating out to the coastal and sea areas during late night to early morning. Based on our climatological records, the frequency of thunderstorms occurrences is high during the inter-monsoon period.

Meanwhile, weak El-Nino conditions are present at the Pacific Ocean since early this year. This synoptic weather influence may contribute to the slight increase in air temperature occasionally exceeding 34℃ for some days. Most global climate centers predicted that weak El-Nino conditions are likely to persist, with 80% chance, until around June 2019.

We shall continue to monitor the weather conditions and will issue weather advisory or warnings if necessary.
