Weather in August

The last month of the summer, August, is another hot month in McKenzie, Tennessee, with an average temperature varying between 68.2°F (20.1°C) and 87.4°F (30.8°C).

Temperature

August's arrival brings an average high-temperature of a still tropical 87.4°F (30.8°C), demonstrating subtle variation from the preceding month. McKenzie reports a consistent average low-temperature of 68.2°F (20.1°C) throughout August nights.

Heat index

During August, the heat index is computed to be a torrid 102.2°F (39°C). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.
Be advised, the heat index considers values for conditions in shade and with a light breeze. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
