Weather in August
Temperature
August brings an average high-temperature of a still hot 86.4°F (30.2°C), nearly identical to the preceding month. Greenville experiences a mean low-temperature of 69.6°F (20.9°C) during August.Heat index
For most parts of August, the heat index is estimated at a torrid 100.4°F (38°C). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.In the scope of the heat index, its values resonate with shade and light wind conditions. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
