Heat index

The heat index for September is computed to be a blazing hot 45°C (113°F). Be wary: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.
Data suggests that the heat index is set for environments in shade and with a light 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 'apparent temperature' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. 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 significant for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
