Heat index

During September, the heat index is estimated at an extremely hot 44°C (111.2°F). Vigilance: Heat cramps and heat exhaustion are likely. The likelihood of heatstroke increases with continued activity.
Keep in mind the heat index values are meant for areas in shade and with light wind. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
