Heat index

The heat index value for August is appraised at a burning hot 113°F (45°C). Notice: Heat cramps and heat exhaustion are likely. Continued strenuous activity might lead to heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light breezes. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
