Heat index

The heat index in September is calculated to be a blistering 104°F (40°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.
It is essential to grasp that the heat index's numbers are for shade and light wind settings. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
