The last month of the summer, August, is another tropical month in Westlyn, Tennessee, with temperature in the range of an average low of 65.1°F (18.4°C) and an average high of 87.1°F (30.6°C).Temperature
The beginning of August records an average high-temperature of a still hot 87.1°F (30.6°C), marking a negligible difference from July's 87.8°F (31°C). August presents a pronounced difference from daytime highs, with a consistent average low-temperature of 65.1°F (18.4°C).Heat index
August's average heat index is estimated at a very hot 98.6°F (37°C). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.Realize that the values for the heat index are set for shaded places and light winds. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical to babies and toddlers. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
