For August, the heat index is evaluated at a hot 87.8°F (31°C). One might feel worn out with persistent exposure and activity, resulting in heat cramps.Note that heat index values are valued for light wind and location in the shade. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
