Weather in Bintulu

Find out what weather awaits you in Bintulu so that your trip is as comfortable as possible. Below are current data, detailed forecasts, and useful charts for planning your trip.

Bintulu, located in Malaysia, is characterized by a classic equatorial climate. Eternal summer reigns here: the weather remains hot and humid throughout the year, without sharp temperature fluctuations. The average air temperature consistently holds around +27°C, creating conditions where the concepts of "winter" and "summer" lose their usual meaning.

Instead of temperature seasons, the year is divided by rainfall intensity, although rains are frequent visitors at any time. Even in relatively "dry" months, such as June and July, the number of rainy days remains high (more than 20 days per month). The wettest period falls at the end and beginning of the year — from November to January, when precipitation can occur almost daily under the influence of monsoons.

Travellers should expect consistently warm weather with daily highs of around +30°C and comfortable night-time temperatures of around +24°C. Due to the high probability of tropical downpours, which are often heavy but can end quickly, it is recommended to always have rain protection with you, regardless of the chosen travel date.

The climate in Bintulu is distinguished by enviable stability: an eternal tropical summer reigns here. Throughout the year, the average air temperature fluctuates within a very narrow range, remaining at the level of +26.6°C to +27.8°C. Thanks to the proximity to the equator, there are no sharp seasonal changes here, so travellers will not have to worry about warm clothes — the weather is conducive to beach holidays and walks in any month.

The conditional peak of heat falls in May, which can be called the warmest month of the year: daytime figures reach an average of +30.9°C, and nights remain very warm (about +24.8°C). January, February, and December are considered the "coolest" months, however, the difference is barely perceptible: during the day, the air warms up to +29.3°C...+29.5°C. A characteristic feature of the local climate is the moderate difference between daytime heat and night-time freshness — the difference is approximately 5–6 degrees, which brings pleasant relief after the midday heat.

The concepts of "winter" and "summer" in Bintulu are quite relative. The winter period here feels like a mild, humid summer, when there is no exhausting heat, and the temperature stays at comfortable levels for the tropics. Summer months, especially from April to July, are characterized by consistently high temperatures. In general, warm and humid weather is typical for the region all year round, without frosts or extreme heat going beyond +31°C.

The climate of Bintulu is characterized by high humidity and regular precipitation throughout the year. It is difficult to single out a clearly defined dry season here, as rains are constant companions of the local weather. Travellers should be prepared for the fact that a clear sky can quickly be replaced by precipitation, so an umbrella or a light raincoat will become indispensable items in your luggage regardless of the travel date.

The wettest period falls at the end and beginning of the year. December is the absolute leader in precipitation frequency: it rains practically every day in this month (about 30 days), and the level of falling moisture reaches its maximum values. January and November are also distinguished by very high rainfall — precipitation is recorded on average 29 days a month, which makes this season the least predictable for walks.

A relative decrease in the amount of precipitation is observed in the middle of the year. June and July are considered the "driest" months, when the number of rainy days decreases to 21–23. During this period, as well as in April, the volume of rainfall is minimal, which gives tourists more chances to catch stable sunny weather for beach holidays and excursions around Malaysia.

When setting off for Bintulu, it is worth orienting yourself towards the consistently hot and humid tropical climate characteristic of this region of Malaysia. Since the average air temperature holds around 26–28°C all year round, the basis of your wardrobe should consist of light items made from natural breathable fabrics, such as cotton or linen. T-shirts, shorts, light dresses, and loose-fitting trousers will be the best choice. It is not necessary to adhere to the principle of layering here for the sake of warmth, but a light cardigan or a long-sleeved shirt will come in handy for protection from the sun or air conditioners in rooms and transport.

Special attention should be paid to rain protection, as statistics show a large number of rainy days throughout the year (from 21 to 30 days per month). Be sure to take a compact umbrella or a light raincoat with you, which you can always carry in your bag. Despite frequent precipitation, the sun here is very active, so sunscreen with a high SPF factor, sunglasses, and a head covering are necessary even in cloudy weather.

As for footwear, give preference to comfortable sandals or light sneakers that dry quickly and are suitable for long walks. If you plan to visit nature parks in the vicinity of Bintulu, closed shoes will be mandatory for protection against insects. It will also not be superfluous to take repellents with you, as in the humid climate mosquitoes can be active all year round.
