Heat index

The heat index value for September is evaluated at a blazing hot 48°C (118.4°F). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.
Heat index values are typically calculated for conditions of shade and a light breeze. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
