Heat index

In September, the average heat index is evaluated at a blisteringly hot 43°C (109.4°F). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.
From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', reflects the feeling of heat when considering both air temperature and humidity. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
