Weather in September

The first month of the autumn, September, is still a hot month in Guene, Benin, with an average temperature fluctuating between 33.9°C (93°F) and 24.1°C (75.4°F).

Temperature

Guene experiences a recorded average high-temperature of a still tropical 33.9°C (93°F) in September, closely aligned with August's 32.3°C (90.1°F). Guene, during the nights of September, experiences an average temperature drop to a warm 24.1°C (75.4°F).

Heat index

For September, the heat index is evaluated at a blazing hot 45°C (113°F). Vigilance: Heat cramps and heat exhaustion are likely. The likelihood of heatstroke increases with continued activity.
Data suggests that the heat index is set for environments in shade and with a light wind. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', quantifies the warmth felt when relative humidity is considered. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Humidity

The average relative humidity in September is 67%.
