Bandar Seri Begawan Weather in May

May: hot and very wet

May feels sticky from morning to evening, with highs around 30°C and little relief after dark. Rain falls on 28 days, and it's tied with June as the wettest month in the data. Cloud and humidity are high, so don't expect much sunshine.

You can still visit the Omar Ali Saifuddien Mosque and browse the covered stalls at Tamu Kianggeh. Keep outdoor sightseeing flexible: heavy showers can interrupt a walk along the waterfront, and the heat makes long stretches on foot tiring. A boat ride through Kampong Ayer is a good way to see the water village between showers.

Events and crowds

Brunei Armed Forces Day falls on 31 May. Ceremonies may mark the occasion, but it isn't a reason to expect a large visitor festival across the capital. Hari Raya dates follow the Islamic calendar, so the holiday can fall in May in some years, bringing family visits and changed opening hours.

If you hate crowds, May is generally quieter than February and March, which are among the best months to visit. It's not a peak sightseeing season, and prices are usually less driven by tourist demand than during busier travel periods. Still, check local opening times if your visit overlaps a public holiday.

Make the rain work for you

Plan outdoor stops around the weather, then use a shower as a cue to pause for ambuyat, Brunei's starchy sago dish, with its dipping sauce. The Royal Regalia Museum is a handy indoor stop near the city centre when rain sets in.

Travelling with kids? Keep the Kampong Ayer visit short if the weather turns: the wooden walkways can be slippery after rain. June is just as wet, while April is also rainy, so May isn't a dry-season bargain.
