August, the last month of the summer in Greenback, is another tropical month, with temperature in the range of an average low of 64.2°F (17.9°C) and an average high of 86.5°F (30.3°C).

Temperature

Greenback records an average high-temperature of a still tropical 86.5°F (30.3°C) as August arrives, nearly mirroring the previous month's climate. The temperature notes a substantial fall from the daily peak to an average of 64.2°F (17.9°C) during August nights.

Heat index

The heat index in August is computed to be a torrid 98.6°F (37°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.
Heat index determinations are made taking into account the shade and light air movements. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a numerical representation of warmth when taking temperature and moisture levels into account. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
