Brunei Weather and Climate
Brunei’s steamy climate is typical of other equatorial regions, with humid balmy temperatures and consistent rainfall throughout most of the year. Annual monsoon winds create the only variation in Brunei’s climate. A northeast monsoon covers the country from December through March, and a southeast monsoon blows from June through October. During these rainy spells, heavy showers mean significant amounts of precipitation. The wettest months are December and January, making this one of the least favorable times to visit despite the holiday season.
The little amount of variation between the wet and dry seasons ensures Brunei has reliably humid air all year round. Average humidity levels hover at around 80 percent, while average daytime temperatures stay near or above 84°F. Of course, the high humidity makes conditions much stickier and more uncomfortable than the temperature suggest.
There are two windows between the monsoons which provide a marked drop in precipitation. Between April and May, and November to early December, conditions are at their driest. This is a popular time to visit Brunei, though the temperatures in March and April are at their peak. Lightweight clothes and a good rain jacket are essential items of clothing to keep comfortable in this steamy tropical country at any time of year.
Visitors to Brunei may not even notice the slight seasonal variations that take place throughout the year despite the fact that the country’s seasons can be divided into wet and dry. Humidity and rain are constants here, with winds and heavy rains from the northeast monsoon occurring from December through March and similar conditions present from June through October when the southeast monsoon blows in.
Wet season: Humidity of around 80 percent and mild temperatures are a feature of the wet season. You’ll need a rain coat for protection against the heavy rains that occur from June through October (southeast monsoon) and December through March (northeast monsoon).
Dry season : Brunei’s dry season offers little difference in humidity from its wet season, with the only change being less precipitation and higher temperatures in the mid-80s (°F). Despite fewer rainy days, visitors can expect the usual sticky conditions.
