Weather in August
Temperature
The commencement of August introduces an average high-temperature of a still hot 86.5°F (30.3°C), closely mirroring the preceding month. During August nights, Joelton witnesses a consistent average temperature of 67.5°F (19.7°C).Heat index
The heat index value for August is evaluated at a sweltering 98.6°F (37°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.Note that heat index values are valued for light wind and location in the 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 an aggregate value of air's warmth and moisture to show the human-felt temperature. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
