Stay informed about the current meteorological situation in Mulu. In this section, you will find the latest weather data and detailed forecasts to help you plan a comfortable journey.

Mulu welcomes travellers with a classic equatorial climate, characterised by high humidity and stable heat year-round. An eternal summer reigns here, and the concept of changing seasons is quite nominal: the average daily air temperature remains practically unchanged, holding at a comfortable mark of around +25…+26 °C. During the day, the air usually warms up to +30 °C, while nights bring a pleasant freshness as the thermometer drops to +22 °C.

A distinctive feature of the weather in this region of Malaysia is regular rainfall. Rains occur frequently here, with the number of rainy days varying from 20 to 30 per month, so there is no distinct dry season in the traditional sense. However, there is no need to be alarmed: tropical showers are often strong but short-lived, quickly giving way to the sun and filling the jungle with life-giving moisture.

Thanks to the absence of sharp temperature fluctuations, you can plan a trip for any month of the year. The weather in Mulu is distinguished by enviable consistency, creating ideal conditions for the growth of lush vegetation. Travellers should be prepared for high humidity and must carry a reliable raincoat to comfortably explore the famous caves and tropical forests, regardless of the whims of the weather.

The temperature regime in Mulu is distinguished by enviable stability, typical of Malaysia's equatorial climate. Throughout the year, average indicators fluctuate within a very narrow range — from +25.3°C to +26.4°C. April and May are considered the hottest months, when the daily maximum reaches +30.2°C. At this time, the weather is truly summery, but without extreme heat, allowing for comfortable exploration of the region's natural attractions.

The concept of "winter" is quite nominal here: even in December and January, which are formally the coolest months, the average temperature decreases only slightly, to +25.3°C. There are no significant seasonal cold spells, but travellers should take into account daily temperature fluctuations. The difference between daytime heat and nighttime is about 7–8 degrees: after sunset, the air cools down to a pleasant +21.7°C…+22.5°C, bringing long-awaited freshness.

When planning a journey to Mulu, it is important to consider that precipitation here is a constant and familiar phenomenon. The climate in this corner of Malaysia is characterised by high humidity, and it rains all year round. A distinct dry season is not observed here, so a high-quality raincoat and waterproof footwear will become essential elements of your luggage.

The highest frequency of precipitation falls during the winter period. In December and January, the number of rainy days reaches a maximum — up to 30 days a month, which means practically daily rains. Spring and autumn are not far behind: in March, May, and November, 28 to 29 days with precipitation are recorded, creating conditions of constant humidity.

The middle of summer can be called a relatively "drier" period. In July, it rains slightly less often, about 20 days per month, which is the lowest figure of the year. However, even at this time, the probability of getting caught in the rain remains very high, so travellers should be ready for weather caprices in any season.

A trip to Mulu is an immersion into a world of tropical jungles where eternal summer reigns. Since the air temperature here remains stable at around +25...+30 °C year-round, the foundation of your wardrobe should consist of light and loose clothing made from natural breathable fabrics, such as cotton or linen. T-shirts, modest shorts, and loose-fitting trousers will be the best choice, allowing the body to breathe in high humidity conditions.

Considering that precipitation falls practically daily, a high-quality raincoat or poncho is a mandatory attribute in your luggage. An umbrella may be inconvenient on forest trails, so it is better to prefer a waterproof cape. Also, comfortable footwear with non-slip soles is extremely important: trekking boots or sandals that dry quickly are ideal for exploring wet paths and caves.

Do not forget about protection from the sun and insects: a head covering, cream with high SPF, and a reliable repellent will make your stay comfortable. For evening walks or trips into deep caves, it is worth bringing long-sleeved clothing and a powerful flashlight. Swimwear will also come in handy if you decide to refresh yourself in local bodies of water after an active day.
