Weather in September

September marks the withdrawal of monsoons in Gakoura. Rainfall starts to retreat significantly to 66mm (2.6"), from its peak in August.

The cloud cover also starts decreasing opening up the sky for clear days again.

Temperature

Gakoura, Mali, observes an average high-temperature of a still tropical 34.6°C (94.3°F) in September, barely different from 33.7°C (92.7°F) in August. In the month of September, Gakoura's average low-temperature falls to a warm 25.4°C (77.7°F).

Heat index

In September, the heat index is calculated to be a burning hot 47°C (116.6°F). Guard: Heat exhaustion and heat cramps are foreseeable. Prolonged effort may bring about heatstroke.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
