Weather in August
Temperature
August denotes a minimal variation in the average high-temperature to a still tropical 86.5°F (30.3°C) from July's 87.4°F (30.8°C). Harpeth Valley, in August, observes a steady average low-temperature of 67.3°F (19.6°C).Heat index
August's mean heat index is computed to be a very hot 98.6°F (37°C). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.Take into consideration that the heat index values are calculated for shade and light wind conditions. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
