Weather in September
Temperature
Kolo records an average high-temperature of a torrid 36.7°C (98.1°F) in September, closely mirroring the climate of the previous month. The low-temperature averages to a moderately hot 26.9°C (80.4°F) during the nights of September.Heat index
The heat index in September is calculated to be a blisteringly hot 44°C (111.2°F). Remain alert: Heat exhaustion and heat cramps are predicted. Extended effort can lead to heatstroke.Heat index details are generally centered around shaded locations and a mild breeze. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a measure of how hot it feels when the actual air humidity is factored in. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Always safeguard yourself; without protection, skin and eyes can get damaged instantly. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Experience reduced UV exposure by about half when donning a wide-brim hat.
