Brunei Climate
This month in numbers
Brunei experienced its 12th warmest April on record in 2026, with an average temperature of 26.96°C, which is 1.0°C above the 1961–1990 baseline. Globally, April 2026 was the 2nd warmest April on record for land temperatures, with an anomaly of +1.1°C.
What changed
The period from February to April 2026 was Brunei's 8th warmest on record, with an average temperature of 26.71°C, a significant 1.2°C above the long-term average. This trend aligns with the broader global picture, as global land temperatures for the same three-month period also ranked as the 2nd warmest on record. Brunei's average temperature is increasing at a rate of 0.25 degrees Celsius every decade.
What’s driving change?
Brunei has been experiencing hot and dry weather conditions, particularly in April 2026, which is part of the inter-monsoon phase that typically lasts until the end of May. This dry spell led to a significant decrease in rainfall, with April 2026 recording only 65.7 millimetres of rain, approximately 70 percent lower than the normal monthly average of 242 millimetres. The prolonged dry and hot conditions contributed to a surge in forest and bush fires, with 135 incidents recorded throughout April, destroying approximately 68 hectares of land. The country has seen a number of bush and forest fires during El Niño occurrences in the past, such as in 1997–1998 and 2015–2016.
Looking ahead
Brunei is currently in the inter-monsoon phase, which is expected to continue until the end of May 2026, suggesting a continuation of warm and potentially dry conditions.

FAQs
How is the climate in Brunei changing?
Brunei is warming in line with the rest of the world. The page above shows the latest monthly temperature anomaly versus the 1961-1990 baseline, the long-term annual trend, and the region's rank in the historical record. The trend rate is shown as °C per decade in the headline panel; you can also see the warmest and coolest years on file.
Where does the climate data for Brunei come from?
Climate data for Brunei comes from Our World in Data, sourcing Copernicus ERA5 and HadCRUT5 (national temperature anomaly) and the Global Carbon Project via Our World in Data (CO₂ emissions), refreshed every month, when the upstream temperature and rainfall data are refreshed.
What is the climate baseline used on this page?
Anomalies on this page are calculated against the 1961-1990 climatological baseline, which is the standard reference period used by the Met Office, NOAA, IPCC and most national climate services. Some panels also show the source-native 1901-2000 (NOAA) or 1991-2020 (WMO) baselines for verification. See Methodology & Sources for the full reference.
Which areas does the Brunei climate data cover?
Temperature, rainfall and emissions data for Brunei Brunei climate profile with temperature anomalies, rainfall (CRU TS), warm/wet-season shift analysis, CO₂ emissions (Our World in Data) and electricity generation mix — all vs the 1961–1990 baseline..
How often is the Brunei climate update refreshed?
The Brunei climate update is refreshed monthly, typically a few days after the previous month closes and the upstream provider (Met Office HadUK-Grid, NOAA Climate at a Glance, Copernicus ERA5 or the Global Carbon Project) publishes its update. See the Climate Rankings for cross-region comparisons.
