Heat index

The heat index in August is appraised at a blistering 104°F (40°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.
Observations indicate that the heat index values are for shady locations with light wind. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
