Heat index

The average heat index in September is estimated at an extremely hot 40°C (104°F). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', gives an indication of how one might feel in terms of heat after considering humidity. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
