Weather in September

September, the first month of the autumn in Bil, is still a tropical month, with an average temperature ranging between max 33.9°C (93°F) and min 24.8°C (76.6°F).

Temperature

As September takes hold, the average high-temperature is a still hot 33.9°C (93°F), nearly mirroring that of the previous month. In the month of September, the nighttime temperature dips to a steady average of 24.8°C (76.6°F).

Heat index

Throughout September, the heat index is appraised at a blazing hot 48°C (118.4°F). Be cautious: Heat exhaustion along with heat cramps are predicted. Heatstroke is a possible consequence of continuous physical effort.
Research indicates the heat index considers values in shaded locales and with light winds. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

UV index

The months with the lowest UV index are January, February, July through September, November and December, with an average maximum UV index of 7. A UV Index reading of 6 to 7 represents a high health vulnerability from unprotected exposure to Sun's UV rays for the average person.
Note: In September, the maximum UV index of 7 suggests these recommendations:
Ward off overexposure. Defence against solar harm is crucial. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
