Weather in August
Temperature
The arrival of August brings an average high-temperature of a still sweltering 95.5°F (35.3°C), closely following the temperature pattern of July. In Chattanooga, the August nights cool down to an average low of 73.9°F (23.3°C).Heat index
In August, the heat index is evaluated at an extremely hot 107.6°F (42°C). Undertake extra safety actions, heat cramps and heat exhaustion are expected. Heatstroke may result from lengthy activity.Be advised, the heat index considers values for conditions in shade and with a light breeze. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'real feel', melds the effects of warmth and moisture to generate a feeling of heat. 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. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for 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 cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
