Weather in Bandung

Planning a trip or simply interested in the weather in Bandung? In this section, you will find the most up-to-date information on weather conditions and detailed forecasts to help you organise your time in the best possible way.

Bandung, located in Indonesia, is characterised by a tropical highland climate. This means that the weather here remains pleasantly warm and relatively stable throughout the year. Average daytime temperatures usually hover in the range of 23-24°C, maximum values reach 26-28°C, and night-time temperatures drop to a comfortable 19-21°C. Sudden temperature changes practically never occur here, making the city attractive for visiting at any time.

Despite the year-round warmth, two main seasons are clearly traceable in Bandung, determined by the amount of rainfall. The wet season usually lasts from October-November to April-May. During these months, it rains very frequently, and the number of rainy days is at its maximum, although the total monthly precipitation is not always extremely high. The air feels more humid during this period. From June to September comes the dry season: the number of rainy days decreases sharply, giving way to sunny weather, and precipitation becomes minimal. This period is often considered the most comfortable for active recreation and excursions.

Thus, the climate of Bandung can be described as mild and predictable. The air temperature remains comfortable all year round, so the main thing to pay attention to when planning a trip is the seasonality of rainfall. If you prefer more sunny days and minimal rain, it is better to choose the months from June to September. However, even in the wet season, rains are rarely prolonged for the whole day, allowing you to enjoy the beauties of the city.

The temperature regime in Bandung is distinguished by pleasant stability throughout the year, which is characteristic of its highland tropical climate. The average annual air temperature fluctuates insignificantly, predominantly in the range of 23-24°C. This creates comfortable conditions for visiting the city in any season. Daytime highs usually reach 26-28°C, and night-time lows rarely drop below 19-20°C, providing pleasant coolness after a warm day.

If we analyse the annual cycle in more detail, the warmest months, with an average temperature of about 24.1-24.3°C, can be called May, September, and October. During these periods, the daytime air temperature can rise to 27.4-28.4°C. The "coolest" months, if one can say so for the tropics, are considered January, February, and July, with average temperatures around 23.3°C. Interestingly, it is in July and August that the lowest night-time temperatures are observed, which can drop to 19.2-19.3°C. This creates a more perceptible contrast between day and night weather. In general, temperature fluctuations during the year are small, and the concepts of "winter" or "summer" in the usual sense are absent here; rather, one can speak of warmer and slightly less warm periods.

The diurnal temperature amplitude in Bandung, that is, the difference between daytime and night-time indicators, averages about 6-8°C. This drop is most pronounced in the drier months, such as July, August, and September, when daytime highs can reach 27.4-28.4°C, and night-time lows drop to 19.2-19.7°C. Such a difference makes evenings and nights refreshingly cool, which is especially pleasant after a warm day. In the wet season, when cloudiness is higher, the temperature difference is usually less significant. The climate of Bandung offers constantly warm, but not exhausting heat, with comfortable nights, making it attractive for tourists all year round.

In Bandung, there is a clearly pronounced seasonality of precipitation, which divides the year into two main periods: wet and dry. The nature of the rains and their frequency change significantly throughout the year, which is an important factor when planning a trip to this Indonesian city.

The wet season in Bandung usually continues from November to April. At this time, rains become a frequent occurrence. The greatest amount of precipitation, according to the provided data, falls in November and December (14 mm each), as well as in February and March (13 mm each). At the same time, the number of rainy days in these months is maximal: for example, in January there are 30, and in November, December, and March — 28-29 days. April also remains rainy with 10 mm of precipitation and 28 rainy days. Frequent precipitation during this period may not always be intense, but it is constant.

The dry season comes to Bandung from June to September, bringing with it a significant reduction in both the total amount of precipitation and the number of rainy days. The driest months are July and August, when only 2 mm of precipitation falls, and the number of days with rain decreases to 13 and 12 respectively. In June and September, a comparatively small amount of precipitation is also observed (4 mm each) and a moderate number of rainy days (20 and 14 days respectively). This period is characterised by the prevalence of sunny weather, which makes it more comfortable for walks and active recreation. May (6 mm, 25 rainy days) and October (8 mm, 23 rainy days) are transitional months between these two seasons.

Preparing for a trip to Bandung, it is important to consider its warm and humid climate, characteristic of the highland tropics of Indonesia. The basis of your wardrobe should consist of light, "breathable" items made from natural fabrics, such as cotton or linen, which will ensure comfort throughout the day at an average temperature of about 23-24°C. Do not forget comfortable shoes for walking, as Bandung and its surroundings offer much of interest to explore. Although during the day the temperature can rise to 26-28°C, evenings can be cooler, with temperatures around 19-21°C, so a light jacket, sweater, or pashmina will be very handy, especially if you are sensitive to temperature changes or plan evening walks.

A key factor when packing is the seasonality of rainfall. The wet season in Bandung lasts approximately from November to May. During this period, especially from January to March and from November to December, it rains very frequently – up to 28-30 days a month. Therefore, indispensable companions will be a compact umbrella or a light raincoat. Clothes that dry quickly can also prove useful. The dry season, occurring in June-September, is characterised by significantly less precipitation (only 2-4 mm in July and August) and fewer rainy days (12-20 days). However, even at this time, a small folding umbrella will not be superfluous in case of a sudden downpour. Regardless of the season, do not forget about sunscreen with high SPF, headwear, and sunglasses, as the sun in the tropics is very active. Insect repellent may also come in handy, especially for walks in nature.
