Weather in August
Temperature
The high-temperature average in August for Simmonsville is a still tropical 90.5°F (32.5°C), staying closely aligned with July's conditions. The average low-temperature during August nights is a pleasant 72.7°F (22.6°C).Heat index
Throughout August, the heat index is calculated to be a life-threatening hot 113°F (45°C). Be cautious: Heat exhaustion along with heat cramps are predicted. Heatstroke is a possible consequence of continuous physical effort.Heat index readings emphasize conditions of light breezes and shaded spots. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
