The first month of the autumn, September, is still a warm month in Sélouma, Guinea, with an average temperature varying between 28.7°C (83.7°F) and 20.3°C (68.5°F).

Temperature

The initiation of September sees an average high-temperature of a still moderately hot 28.7°C (83.7°F), showing minor variations from the previous month. Sélouma observes an average nighttime low-temperature of 20.3°C (68.5°F) during the month of September.

Heat index

During September, the heat index is evaluated at a sweltering 36°C (96.8°F). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.
The standards for the heat index are set for locations in shade and under light breezes. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. On sunny days, it's ideal to wear sunglasses that filter out UVA and UVB rays.
