The climate in Bamako can be characterized as tropical, with distinct dry and wet seasons. The city is known for its hot weather throughout most of the year. Average annual temperatures here are consistently high, so when planning a trip, it is worth being prepared for sun and high temperatures, especially during the daytime.

Two main periods are clearly defined in Bamako. The dry season usually lasts from November to April. During this time, there is practically no precipitation, and days are predominantly clear and sunny. The hottest months are March and April, when daytime temperatures reach their maximum values. May marks the gradual transition to the wet season, which reaches its peak in July and August. These summer months see the highest amount of rainfall, and days are often cloudy, bringing some relief from the intense heat, although the overall air temperature remains high.

Bamako experiences a hot climate year-round, however, temperature indicators vary noticeably depending on the season. The annual range of average temperatures fluctuates from 24.8°C in January to 32.5°C in May. The hottest months are typically April and May, when the average maximum temperature can reach 39.3°C and 38.5°C respectively. During these periods, the daytime heat can be quite intense. The "coolest" months are considered to be December and January, with average minimum temperatures around 17.0°C - 17.5°C, ensuring more comfortable nights.

Summer months, especially from June to September, are characterized not only by high temperatures but also by the onset of the rainy season. Although average temperatures drop slightly compared to the heat peak in April-May (for example, in August the average temperature is 25.7°C, and the maximum is 28.9°C), high humidity can create a feeling of mugginess. The "winter" period, from November to February, brings drier and relatively cooler weather. Average daytime temperatures at this time range from 32.7°C to 35.2°C, but nights become noticeably fresher, with minimum temperatures dropping to 17.0°C in January.

A notable feature of Bamako's climate is significant diurnal temperature fluctuations, especially during the dry season. The difference between daytime highs and nightly lows can be 15-18°C (for example, in January: max. 32.7°C, min. 17.0°C). This means that even after a very hot day, the evening and night can bring pleasant coolness. In the rainy season, these fluctuations smooth out somewhat but remain perceptible.

Bamako sees distinct rainfall seasonality, dividing the year into a long dry period and a shorter but intense rainy season. The dry season dominates from November to April, when precipitation is practically absent. In January, February, March, November, and December, not a single rainy day is registered, and rainfall amounts to zero. April is also very dry with zero rainfall, although there may be a couple of days with insignificant rain.

The rainy season in Bamako usually begins in May (1 mm of precipitation, 6 rainy days) and gradually gains strength, reaching its peak in the summer months. August is the wettest month both in terms of rainfall amount (average 9 mm) and frequency of rain (average 26 rainy days). July is also very rainy, with 8 mm of precipitation and 24 rainy days. During this period, rains can be quite intense, typical of a tropical climate. September still remains wet (6 mm, 20 rainy days), after which the amount of precipitation and its frequency begin to decrease rapidly.

Thus, if you are planning a trip to Bamako and want to avoid rain, the best time to visit is from November to April. During these months, the probability of precipitation is minimal. Conversely, from June to September, and especially in July and August, one should be prepared for frequent rains, which bring high humidity but also some refreshment from the daytime heat.

When planning a trip to Bamako, it is important to choose your wardrobe correctly, considering the hot climate and distinct seasonality. Year-round, you will need light, breathable clothing made from natural fabrics such as cotton or linen. In the dry season, from November to April, when rainfall is practically absent and daytime temperatures can be very high (especially in March and April with highs up to 37-39°C), be sure to bring sunscreen with high SPF, sunglasses, and a hat. Given the significant diurnal temperature fluctuations, when nights can be cooler (17-20°C), a light cardigan or shawl may come in handy for evening walks. Comfortable open shoes or light sneakers will be ideal for this period.

With the onset of the wet season, which lasts roughly from May to October and peaks in July-August, the weather character changes. Although temperatures remain high, frequent rains (up to 26 rainy days in August) bring increased humidity. During this period, you will need an umbrella or a light raincoat. Clothing should be not only light but also quick-drying. Closed but breathable shoes that are not afraid of moisture will be more practical. Don't forget insect repellent, as humid weather promotes their activity. The principle of layering in clothing is also relevant, allowing you to adapt to changing conditions throughout the day – from morning freshness to daytime heat and possible downpours.

Regardless of the season, comfortable walking shoes are a must-have, as you will surely want to explore the city. Do not forget to drink enough water to avoid dehydration in the hot climate of Bamako. A light scarf or handkerchief can be useful not only for sun protection but also for visiting certain places where more modest clothing is required.
