Weather in August
Temperature
With August's advent, Clarksville sees an average high-temperature of a warm 85.6°F (29.8°C), subtly shifted from July's 87.1°F (30.6°C). Nighttime temperatures hover around an average low of 65.8°F (18.8°C) in August.Heat index
The heat index for August is computed to be a torrid 95°F (35°C). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.Realize that the values for the heat index are set for shaded places and light winds. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a numerical representation of warmth when taking temperature and moisture levels into account. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
