Weather in August
Temperature
The transition from July to August sees an average high-temperature of a still warm 81°F (27.2°C), indicating a minor variance from the prior month. Marked by a significant drop from the daytime highs, Unicoi's average low-temperature in August stands at a refreshing 57.7°F (14.3°C).Heat index
August's heat index is calculated to be a tropical 86°F (30°C). Exhaustion is likely with prolonged exposure and activity. Sustaining activity may result in heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', combines both the air temperature and the humidity level to give a perceived human temperature. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
