Heat index

September's average heat index is evaluated at a blisteringly hot 104°F (40°C). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.
Heat index values are typically calculated for conditions of shade and a light breeze. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', offers an insight into how hot it feels when we factor in moisture content. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
