Weather in August
Temperature
Greenville, South Carolina, marks the start of August with an average high-temperature of a still hot 88.5°F (31.4°C), hinting at a slight fluctuation from July's 90.1°F (32.3°C). An average low-temperature of 67.3°F (19.6°C) is recorded in the month of August.Heat index
During August, the heat index is calculated to be a fiery hot 102.2°F (39°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Heat index data is primarily for areas with shade and subjected to light winds. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
