Weather in Bima

Planning your day in Bima? Here you will find the most up-to-date weather information, including detailed forecasts and visual charts.

Bima welcomes travellers with a classic tropical climate typical of this part of Indonesia. The weather here is distinguished by enviable consistency: air temperatures remain comfortable and warm throughout the year. Average figures remain stable around +26...+27°C, making the city an attractive destination for heat lovers regardless of the month chosen for the trip.

Throughout the year, there is a clear shift between wet and dry seasons. The period from December to March is characterised by frequent rainfall and high humidity — at this time, it can rain almost daily. In contrast, from July to September, a distinct dry season sets in, when precipitation drops to zero and the number of sunny days is at its maximum, creating ideal conditions for beach holidays and long walks.

Temperature fluctuations between seasons are minimal, although there are slight differences. The "coolest" months are considered to be July and August, when night temperatures can drop to a pleasant +23°C. The hottest weather is usually recorded in October and November before the start of the rainy season, when daytime highs approach the +30°C mark.

Bima greets travellers with consistently warm weather throughout the year, which is characteristic of Indonesia's tropical climate. The temperature regime here is notable for its consistency: annual averages fluctuate within a very narrow range. The hottest months are October and November, when the average temperature reaches 27.3°C, and daytime highs can rise to almost 30°C. This period precedes the rainy season and feels the most sultry.

Interestingly, the months corresponding to summer in the Northern Hemisphere (June, July, August) are the "coolest" time of year in Bima. In July, the average temperature drops to a comfortable 25.5°C, which, combined with the absence of precipitation, makes this period ideal for tourism. The so-called "winter" (December — February) is characterised by high temperatures around 26°C, but due to high humidity and frequent rains, the heat may feel more intense than in the dry season.

Daily temperature fluctuations in the city are minimal, so tourists are unlikely to need warm clothing. The difference between the daytime maximum and nighttime minimum is usually only 3–5 degrees. Even on the coolest nights of August, the thermometer rarely drops below 23.3°C, and in the warm months, the night temperature remains stable at 25°C, ensuring warm and pleasant evenings for walks by the sea.

The climate in Bima is characterised by a distinct division into wet and dry seasons, typical for many regions of Indonesia. It is important for travellers to consider this factor, as the character of the weather changes drastically throughout the year. Precipitation here falls exclusively as rain, and its frequency depends directly on the month you choose to visit.

The rainy season is quite long and covers the period from November to April. The wettest months are considered to be January, February, and March, when the number of days with precipitation reaches a maximum. For example, in January, an average of about 29 rainy days is recorded, which means a probability of precipitation almost daily. During this period, the sky is often covered with clouds, and air humidity rises.

With the arrival of May, the situation begins to change, and the city enters the dry season, which lasts until October. This is the best time for those who prefer clear weather: the amount of precipitation decreases rapidly. The driest months are July, August, and September. In August, for example, it may rain for only about 2 days during the entire month, and the volume of precipitation is minimal.

Transitional periods, such as April and November, are distinguished by moderate rain frequency (about 17–18 days with precipitation), offering a compromise between the wet and dry seasons. When planning a trip to Bima, guide yourself by these cycles: summer and early autumn are ideal for walks under the sun, while winter and early spring allow you to see tropical nature in all its humid glory.

Since warm tropical weather reigns in Bima all year round with an average air temperature of about +26...+27°C, the basis of your wardrobe should be items made from natural, breathable fabrics, such as cotton or linen. T-shirts, light shirts, shorts, and summer trousers will be the best choice for a comfortable holiday. Given that even at night the temperature rarely drops below +23°C, you are unlikely to need warm clothes, although a light cardigan may be useful for protection from air conditioning in transport or indoors.

When planning a trip, it is important to consider the seasonality of precipitation. The period from December to March is considered the rainy season (in January the number of rainy days reaches a maximum — up to 29 days!), so be sure to pack a compact umbrella or a high-quality raincoat, and choose quick-drying shoes. If you are travelling in the dry season, which lasts from July to September, precipitation is practically excluded. At this time, the sun is especially active, so do not forget sunscreen, sunglasses, and a hat.

For walking around the city and its surroundings, comfortable shoes are ideal: sandals with secure foot support or light sneakers. It is also recommended to take insect repellents with you, as insects can be active in the evening, especially during the wet months. The principle of layering clothing is less relevant here due to the stable temperature, but having a spare set of dry clothes during the rainy season will be very handy.
