Stay up to date with the current weather conditions in Bandar Seri Begawan. Below you will find the latest information, forecasts, and useful weather charts.

The climate in Bandar Seri Begawan is characterized as equatorial, which means high temperatures and humidity all year round. Average temperatures here are very stable, fluctuating within the range of 26-28°C throughout the year. Minimum nighttime temperatures rarely drop below 24°C, while daytime highs usually hover around 28-30°C. This creates a sensation of constantly warm, tropical weather, ideal for those seeking sun and warmth.

There are no clearly defined seasons in the traditional sense, such as hot summers and cold winters, in Bandar Seri Begawan. The weather is rather divided into periods with more or less rainfall. Data shows that rain falls quite frequently throughout the year: the number of rainy days varies from 20 to 29 per month. Although the total monthly rainfall, according to the provided data, is low (from 5 to 10 mm), the high frequency of rainy days (from 20 to 29 per month) contributes to maintaining high air humidity. The greatest amount of precipitation and rainy days is usually observed in the period from October to December.

The temperature pattern in Bandar Seri Begawan is remarkably stable throughout the year, which is typical for an equatorial climate. Average annual temperatures fluctuate within a very narrow range. Minimum nighttime temperatures usually stay within 24.3°C - 25.4°C, while daytime maximums reach marks from 28.2°C to 29.7°C. Such insignificant annual amplitude makes the weather predictably warm at any time of year, without sharp seasonal changes.

If we highlight the warmest periods, May is usually the hottest month, with an average temperature of 27.6°C and maximum daytime values reaching an average of 29.7°C. The months from April to September are generally characterized as the warmest, when daytime temperatures consistently stay above 29°C. The "coolest" months, insofar as this applies to the tropics, can be considered January and February, when the average temperature is about 26.3°C, and minimum nighttime temperatures drop to 24.3°C - 24.4°C. However, even during these periods, the weather remains very warm and comfortable.

Daily temperature fluctuations in Bandar Seri Begawan are small. The difference between the average maximum daytime and average minimum nighttime temperature during a single month is usually only about 4-4.6°C. This means that nights bring only slight relief from the daytime heat, maintaining the feeling of constantly warm and, given the frequent rainfall, humid weather typical for this region of Brunei.

Precipitation in Bandar Seri Begawan is an integral part of the climate all year round, which is typical for the equatorial zone. There is practically no clearly defined dry season here; rather, periods with slightly fewer or more rainy days and rainfall volume are observed. Travelers should be prepared for the fact that rain may fall on any day of their visit, so a light umbrella or raincoat will not go amiss.

The wettest months, both in terms of rainfall amount and frequency, are traditionally considered November and December. During these months, an average of 10 mm of precipitation falls, and the number of rainy days reaches an impressive 29 days per month. October also belongs to the wet period, with a figure of 9 mm of precipitation and 28 rainy days. Comparatively "dry" months, if one can say so in equatorial climate conditions, can be called February and March, when the monthly rainfall norm is only 5 mm, and the number of days with rain decreases to 22-23. July stands out with the lowest number of rainy days in the year – on average 20, with a rainfall volume of 6 mm.

A characteristic feature of precipitation in Bandar Seri Begawan is its high frequency with a relatively small total volume. For example, even in months with the least amount of rainfall, such as February or March (5 mm), it rains on average 22-23 days. In peak months, like November and December, there are up to 29 rainy days. This indicates that precipitation most often does not represent prolonged heavy downpours, but rather frequent, but light or moderate rains, which contribute to maintaining high air humidity throughout the year.

When planning a trip to Bandar Seri Begawan, it is important to consider its equatorial climate, which is characterized by consistently high temperatures and high humidity year-round. The average temperature stays around 26-28°C, so the foundation of your wardrobe should be light, breathable clothing made from natural fabrics such as cotton, linen, or viscose. Since there are very many rainy days in Bandar Seri Begawan throughout the year (from 20 to 29 days per month), even with a small total rainfall volume, a compact umbrella or a light waterproof raincoat will become your indispensable companions. Frequent, albeit often short-lived, rains are a common occurrence for Brunei.

Besides light clothing, be sure to bring comfortable shoes for walking, as you will likely want to explore the city's sights on foot. Do not forget sunscreen with a high protection factor, a hat, and sunglasses to protect against the active tropical sun. Although the air temperature remains high even in the evening, a light jacket, cardigan, or shawl may come in handy for visiting air-conditioned premises (for example, shopping malls or museums) or if you are sensitive to evening coolness, although it is minimal. The principle of layering here is not so relevant for protection from cold as for comfort in different situations – for example, to throw something light over your main outfit. The greatest amount of precipitation falls in the period from October to December, but readiness for rain is important at any time of year.
