Weather in August

During August, the average high-temperature is a still hot 89.6°F (32°C), maintaining a close resemblance to that of the preceding month. In Knoxville, August nights witness a steady temperature drop to a pleasant 72.1°F (22.3°C).Heat index
The heat index for August is calculated to be a blisteringly hot 107.6°F (42°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.For clarity, heat index numbers account for light winds and areas under shade. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
