Weather in September
Temperature
The shift from August to September is characterized by an average high-temperature of a still moderately hot 29.7°C (85.5°F), not significantly different from the 29.3°C (84.7°F) of August. Throughout September, Mongoumba experiences a low-temperature average of 20.4°C (68.7°F).Heat index
The heat index in September is estimated at a torrid 38°C (100.4°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Note that heat index values are valued for light wind and location in the shade. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', ties air temperature with relative humidity to produce the perceived temperature sensation. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. As body temperatures escalate without effective heat release, one might face dehydration threats.
