Heat index

During July, the heat index is computed to be an extremely hot 43°C (109.4°F). Heed: Expect heat cramps and heat exhaustion. Continued action may cause heatstroke.
Heat index determinations are made taking into account the shade and light air movements. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is found by incorporating humidity levels into the air temperature measurement. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
