The best time to visit Brunei is usually February and March, the driest months, when National Day on 23 February also takes place. Brunei is hot, humid and rainy all year, so there’s no perfect season. Late October to January is a little cooler but wetter, and heavy rain can restrict access to Temburong.
What is the weather like in Brunei?
Brunei has a tropical rainforest climate. Temperatures rarely drop below 23°C, according to Responsible Travel, and humidity stays high all year. Rain can fall at any time, often in short, heavy bursts. If you’re reading this in late October or November, you’re at the start of the wetter period.
The cooler season is only slightly cooler. For most visitors, the practical question isn’t temperature but how much rain you can accept on rainforest and boat days.

Which months suit which trip?
- Rainforest and outdoor trips: February and March, when rain is usually lighter.
- Festivals and culture: 23 February for National Day, or mid-July for the Sultan’s birthday.
- Fewer crowds and lower prices: outside the main festival dates, with a rain jacket in your bag.
- City and museum trips: any month, since much of the programme is indoors.
Does Ramadan affect travel?
Yes. Ramadan moves each year. Under Brunei’s Sharia Penal Code, eating, drinking or using tobacco in public during fasting hours is an offence, according to the US State Department. Many cafés and restaurants adjust their hours, and daytime dining options can be limited. Plan meals in advance, eat in your hotel or at venues that clearly serve daytime visitors, and be respectful. The days around Hari Raya Aidilfitri, the festival after Ramadan, bring family gatherings and busier roads.
Many shops, offices and attractions also change hours around Friday midday prayers, so check opening times before you go. Public holidays can also affect transport and tours.
What should you pack?
- Light, loose clothes that cover shoulders and knees.
- A light layer for air-conditioned buildings.
- A rain jacket or umbrella.
- Sun protection, a hat and insect repellent.
- Comfortable walking shoes or sandals that are easy to remove at mosques.
- A scarf for women who plan to visit mosques.
- Copies of your documents and your E-Arrival Card confirmation.
Common mistakes
- Planning Temburong on the wettest days without a flexible schedule.
- Expecting daytime restaurants to be busy during Ramadan.
- Visiting in mid-July without booking ahead for hotels.
- Dressing for the heat in clothes that are too short for mosques and public places.
