Heat index

Throughout September, the heat index is calculated to be a burning hot 58°C (136.4°F). Warning: These weather conditions are understood as severely treacherous, heatstroke is approaching.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
