Weather in August

The last month of the summer, August, is also a hot month in Stonewall, Tennessee, with an average temperature varying between 65.8°F (18.8°C) and 86°F (30°C).

Temperature

August is marked by an average high-temperature of a still hot 86°F (30°C), almost identical to the preceding month. In Stonewall, the August nights cool down to an average low of 65.8°F (18.8°C).

Heat index

Throughout August, the heat index is appraised at a very hot 98.6°F (37°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.
Heat index readings emphasize conditions of light breezes and shaded spots. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

As much as possible, limit direct sun exposure during this period. Arm yourself against UV rays' harm with protective apparel and UV-filtering shades.
