Heat index

The heat index for October is appraised at a blazing hot 47°C (116.6°F). Forewarned: Heat cramps and heat exhaustion are anticipated. Ongoing physical activity increases the likelihood of heatstroke.
Be advised, the heat index considers values for conditions in shade and with a light breeze. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', binds temperature metrics with humidity values to give a sense of the actual warmth. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
