Despite lesser rain, September still maintains high humidity. With the reducing rainfall, the weather starts to incline towards drier conditions.

Temperature

As Guinagourou transitions into September, the average high-temperature stands at a still warm 29.4°C (84.9°F), offering little variation from the preceding month. The average low-temperature, in September, is an agreeable 21.9°C (71.4°F).

Heat index

During September, the heat index is evaluated at a sweltering 37°C (98.6°F). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', determines the feeling of heat when you account for the relative humidity. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. 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 quite important for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Humidity

The average relative humidity in September is 85%.
