August's average heat index is appraised at a blazing hot 114.8°F (46°C). On guard: Heat exhaustion and heat cramps are predicted. Heatstroke is a potential hazard with continuous physical effort.
Heat index determinations are made taking into account the shade and light air movements. 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 'feels like' or 'apparent temperature', is the outcome of merging air's temperature and its humidity metrics. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. As body temperatures escalate without effective heat release, one might face dehydration threats.
