Heat index

The heat index in September is evaluated at a blisteringly hot 40°C (104°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative 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. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular importance for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
