The climate in Brunei

Average daytime and nighttime temperatures


All climatic diagrams of this page are taken from the collected data from 2 measuring stations in Brunei.
All data correspond to the average monthly values of the last 20 years.


Back to overview: Brunei


Climate zone: tropics

High humidity in Brunei and high temperatures are causing a pleasant weather at times, but also and partly tropical hot and humid. It is yearlong warm or hot. Dued to the lesser rain the best time for traveling is from February to March. Most precipitation decrease in November.

Temperature records of the last 34 years

The hottest temperature measured from 1987 to June 2021 was reported by the Brunei Airport weather station. In August 2000 the record temperature of 39.1 °C was reported here. The hottest summer from July to September was recorded in 2019 with an average temperature of 28.5 °C. This average temperature will normally be measured every 4 to 6 hours, thus also including the nights. Normally, this value is 27.7 degrees Celsius. The average maximum daily temperature at that time was 33.2 °C.

The coldest day in these 34 years was reported by the weather station Brunei Airport. Here the temperature dropped to 20.6 °C in January 2010. Brunei Airport lies at an altitude of 15 meters above sea level. The coldest winter (January to March) was in 1996 with an average temperature of 26.4 °C. In Brunei, it is usual to have about 0.9 degrees more at 27.3 °C for this three-month period.

The most precipitation fell in Januar 2009. With 31.5 mm per day, the Brunei Airport weather station recorded the highest monthly average of the last 34 years.




Long-term development of temperatures from 1995 - 2020

In contrast to single record values, a long-term development cannot simply be brought about by all weather stations in the country. Both the number and the locations are constantly changing. A simply calculated average value would give a falsified result. If several measuring stations in particularly cold mountain or coastal regions are added in one year, the average would already decrease as a result of this alone. If a station fails during the summer or winter months, it does not provide any values and falsifies the average again. The subsequent long-term development was therefore reduced to only 1 measuring points in order to have actually comparable data over as long a period as possible.

In the years 1995 to 2020 there were only these 1 weather stations in the whole country, which reported continuous temperature values (Bruneiort). From these weather reports we have created a long-term development that shows the monthly average temperatures. The hottest month in this entire period was 1998 with 29.5 °C. 1996 was the coldest month with an average temperature of 25.7 °C.

The average annual temperature was about 27.4 °C in the years after 1995 and about 28.0 °C in the last years before 2020. It has therefore increased only slightly by about 0.6 °C over the past 26 years. This trend only applies to the selected 1 weather stations in Brunei. A considerably more comprehensive evaluation of the global warming has been provided separately.
