The climate in Bujumbura, the capital of Burundi, can be described as tropical savanna, with pleasantly warm temperatures throughout the year. The average annual temperature fluctuates very little, usually remaining within the 22-24°C range, creating comfortable conditions for visiting at any time. Daytime highs rarely drop below 26°C and can reach 28°C, while nights remain warm with minimum temperatures around 18-19°C.

Two main seasons are clearly distinguished in Bujumbura: dry and rainy. The dry season typically lasts from June to August, characterized by minimal rainfall and the fewest number of rainy days, especially in July. The rainy season covers most of the year but is most pronounced during the periods from March to April and from October to December. During these months, particularly in April and December, the highest number of days with precipitation is observed, although the rains themselves may not always be heavy in volume.

The temperature pattern in Bujumbura is notable for its enviable stability throughout the year. Average annual temperatures fluctuate within a very narrow range, typically from 22.5°C (in June and July) to 23.7°C (in September). Daytime highs also do not undergo sharp spikes, varying on average from 26.5°C (in January, April, December) to 28.4°C (in September), while nighttime lows usually stay within comfortable limits of 18.1°C (in July) to 19.2°C (in February, March, April, and October). This creates a sensation of constantly warm weather, ideal for those who prefer to avoid both exhausting heat and cold.

The warmest months, judging by daily average and maximum temperatures, are September (average temperature 23.7°C, maximum up to 28.4°C) and October (average 23.6°C, maximum up to 28.1°C), as well as February (average 23.5°C, maximum up to 27.8°C). During these periods, days are usually hot but generally not excessively sultry. The "coolest" months, if one can use that term for such a consistent climate, are considered June and July, when the average temperature is around 22.5°C, and nighttime lows can drop to 18.1°C - 18.3°C. Despite the general stability, noticeable daily temperature fluctuations are observed in Bujumbura: the difference between daytime highs and nighttime lows can reach 7-9.5°C, ensuring fresher and more comfortable evenings and nights, especially after a warm day.

In Bujumbura, the pattern of rainfall clearly divides the year into two main seasons, creating a marked contrast between wet and dry periods. The rainy season here is quite prolonged, covering most of the year; however, its peak activity falls on specific months.

The wettest period in Bujumbura, when precipitation is most likely, is the interval from October to April. Among these months, April and December stand out as leaders in rainfall amounts – averaging 12 mm each. December is also distinguished by the highest number of rainy days (on average 24 days), followed by April with a figure of about 22 days. Months such as January (9 mm, 21 days), March (8 mm, 20 days), and November (9 mm, 19 days) are also characterized by a significant number of days with precipitation, making rain a frequent occurrence during this period.

A complete opposite to the wet season is the dry season, which is most clearly expressed from June to August. July is the absolute record holder for dryness: only about 1 mm of precipitation falls in this month, and the number of rainy days drops to a minimum – just five. June is also notable for a small amount of rainfall (1 mm) and a low number of rainy days (8 days). In August, a slight increase is observed in both rainfall volume (2 mm) and the number of rainy days (9 days). May and September act as transitional months when the weather gradually changes: in May, rainfall amounts to 4 mm with 13 rainy days, and in September – also 4 mm, but with 14 rainy days, heralding the onset of the wetter period.

When packing your suitcase for a trip to Bujumbura, plan for the warm tropical weather that prevails here year-round. The foundation of your wardrobe should consist of light, breathable clothing made from natural fabrics, such as cotton or linen, suitable for temperatures from 18°C to 28°C. Do not forget comfortable shoes for walking around the city and its surroundings, as you will surely want to explore the local beauty. Essential companions will be high SPF sunscreen, sunglasses, and headwear (a hat or cap) to protect against the active sun, which is intense here even on cloudy days. It is also recommended to bring insect repellent, especially for evening walks.

Given the pronounced rainy season, which lasts roughly from October to April (peaking in rainy days in December, April, January, and March), be sure to pack a light raincoat or a compact umbrella. Quick-drying clothes can also prove very practical during this period. In the drier season, from June to August, when rainfall is minimal, the focus shifts to the lightest summer clothing. However, since evenings can be slightly cooler (temperatures dropping to 18-19°C), a thin sweater, light jacket, or stole will come in handy for comfort. The principle of layering in clothing will be useful in any season, allowing you to easily adapt to weather changes throughout the day – from sunny heat to a sudden downpour or evening freshness.
