Heat index

September's average heat index is computed to be an extremely hot 40°C (104°F). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.
It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, 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 especially vital to children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
