January weather forecast
Brunei

January is situated firmly within Brunei's wet season. Consequently, the month witnesses elevated levels of precipitation. In fact, January stands out as one of the months with the most substantial rainfall, only slightly behind December in terms of precipitation volume. This is a result of the active northeast monsoon, which dominates the region during this period.

While the skies are predominantly overcast, temperatures in January are relatively mild for the region. They typically fluctuate from 20°C (68°F) to 28°C (82.4°F), ensuring that the days remain warm. Of particular note, January experiences some of the lowest temperatures of the year, with the average lows dropping to about 22.8°C (73°F).

Comparatively, when juxtaposed with December, January maintains similar temperature profiles, though the latter might witness slightly reduced rainfall. However, when contrasted with February, January is distinctly cooler and rainier. This shift in weather conditions marks the transition towards the drier months of the year.

While Brunei is relatively small, and weather patterns are consistent throughout the nation, Banda Seri Begawan, the capital city, could be slightly warmer due to the urban heat island effect. However, this difference is often negligible and doesn't drastically deviate from the national average.

The winds in January are noteworthy, as this month is part of the windiest season in Brunei. Wind speeds typically remain in the range of 7.4km/h (4.6mph) to 11.7km/h (7.3mph), influenced by the prevailing northeast monsoon.
