Weather in September
Temperature
With the start of September, Babel measures an average high-temperature of a still hot 32.7°C (90.9°F), not significantly differing from August's 32°C (89.6°F). Babel in September experiences a low-temperature average of 22.5°C (72.5°F).Heat index
September's average heat index is evaluated at a burning hot 47°C (116.6°F). Stay watchful: Heat exhaustion along with heat cramps are likely. Ongoing effort may cause heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'real feel' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. 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.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
