September, the first month of the autumn in Katofou, is a torrid month, with an average temperature fluctuating between 36.2°C (97.2°F) and 26.5°C (79.7°F).Temperature
The start of September signals a slight increase in the average high-temperature, moving from a hot 33.2°C (91.8°F) in August to a very hot 36.2°C (97.2°F). Throughout September, an average nighttime temperature of 26.5°C (79.7°F) is experienced.Heat index
Throughout September, the heat index is calculated to be a blistering 42°C (107.6°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.In terms of the heat index, values are set with light wind and shade conditions in mind. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. 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.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

March through July, September and October, with an average maximum UV index of 8, are months with the highest UV index. A UV Index estimate of 8 to 10 represents a very high health risk from unsafe exposure to UV radiation for ordinary individuals.Note: A daily high UV index of 8 in September leads to these guidelines:
Ensure you're always protected. Unprotected skin can get damaged in moments. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. Arm yourself against UV rays' harm with protective apparel and UV-filtering shades.
