September registers as the month with the highest average temperatures, reaching 36.9°C (98.4°F) at its peak and 22.7°C (72.9°F) at the lowest.Heat index
September's average heat index is computed to be a life-threatening hot 45°C (113°F). Beware: Heat exhaustion along with heat cramps are on the cards. Heatstroke could result from sustained physical activity.In reference to the heat index, it's for places in shade and with a slight wind. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', reflects the feeling of heat when considering both air temperature and humidity. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
