Heat index

The heat index value during August is calculated to be a blisteringly hot 107.6°F (42°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
