Heat index

The heat index value for August is estimated at an extremely hot 40°C (104°F). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.
Heat index details are generally centered around shaded locations and a mild breeze. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
