May weather forecast
Bamako, Mali

May indicates the onset of the rainy season in Bamako. Rainfall escalates dramatically to 54mm (2.13") from the meager 20mm (0.79") last April. This increase in precipitation leads to a humidity surge to 50%. Concurrently, the mean temperature plateaued at 38.5°C (101.3°F) defines the climatic interplay with both hot and wet conditions. The rising water levels of the Niger River reflect the atmospheric change, signaling the perfect time for river-based excursions.

Temperature

The commencement of May in Bamako records an average high-temperature of a still torrid 38.5°C (101.3°F), barely varying from April's 39.6°C (103.3°F). Bamako anticipates a considerable cooling off from the daytime high to an average minimum temperature of 25.4°C (77.7°F) in May.

Heat index

May's heat index is evaluated at a burning hot 50°C (122°F). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.
Heat index readings emphasize conditions of light breezes and shaded spots. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', gives an indication of how one might feel in terms of heat after considering humidity. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Carry out all vital precautions. Protection from sun exposure is a must. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes. One should apply and reapply liberally a broad-spectrum sunscreen of SPF 30+ every two hours and immediately after a swim or an outdoor exercise.
