Weather in July
Temperature
Knoxville experiences its highest temperatures in July, with an average peak of 88.9°F (31.6°C) and a low of 66.7°F (19.3°C).Heat index
The heat index in July is computed to be a blistering 104°F (40°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. 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 extremely vital to babies and toddlers. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Ward off overexposure. Defence against solar harm is crucial. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection.
