Weather in August
Temperature
With the start of August, Harpeth measures an average high-temperature of a still tropical 86.5°F (30.3°C), not significantly differing from July's 87.4°F (30.8°C). Throughout the nights in August, Harpeth experiences an average low-temperature of 67.6°F (19.8°C).Heat index
In August, the average heat index is computed to be a sweltering 98.6°F (37°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', gives an indication of how one might feel in terms of heat after considering humidity. 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. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
