Weather in September
Temperature
September's advent denotes a minor fluctuation in the average high-temperature to a still very hot 37.1°C (98.8°F) from August's 35.3°C (95.5°F). Fatoma, in September, witnesses an average low-temperature of 27.5°C (81.5°F).Heat index
During September, the heat index is evaluated at a blistering 44°C (111.2°F). On guard: Heat exhaustion and heat cramps are predicted. Heatstroke is a potential hazard with continuous physical effort.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', gauges the sensation of temperature factoring in the air's moisture content. Physical activity, clothing, and metabolic variations are additional factors that impact an 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 extremely vital to 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.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Sunshine
The average sunshine in September is 9.6h.UV index
In Fatoma, the average daily maximum UV index in September is 8. A UV Index reading of 8 to 10 represents a very high health vulnerability from unprotected exposure to Sun's UV rays for average individuals.Note: In September, a daily maximum UV index of 8 leads to the following instructions:
Take extra precautions. Fair-skinned individuals may get burned in less than 10 minutes. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation. Take careful note! The UV radiation of the Sun can be nearly doubled by snow reflection.
