Heat index

The heat index value during May is estimated at a blistering 43°C (109.4°F). Take heed: Heat exhaustion and heat cramps are anticipated. Heatstroke is a potential outcome of continuous activity.
The heat index's values are generally associated with conditions in shade and light breezes. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', gives an indication of how one might feel in terms of heat after considering humidity. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
