August weather forecast
Lebanon, TN

Following the heatwave of July, Lebanon, Tennessee welcomes an August graced by a slight dip in average maximum temperature to 86.4°F (30.2°C). This month, acting as a transitional period, says goodbye to the peak summer heat and ushers in the coolness of the forthcoming autumn. Though August offers more rainfall as compared to July, it is just a gentle precursor to the wet days of September. However, the wind velocity remains constant, offering only a slight hint of the increased gust speeds that await in September. August, balancing the tail-end of summer and the advent of fall, hosts a bevy of weather elements, indicating the imminent arrival of autumn.

Temperature

August brings an average high-temperature of a still hot 86.4°F (30.2°C), nearly identical to the preceding month. Lebanon's nighttime temperature during August is consistently averaged at a comfortable 66.9°F (19.4°C).

Heat index

Throughout August, the heat index is computed to be a very hot 98.6°F (37°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.
Given the heat index, its values are aligned with shaded sites and gentle winds. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'real feel' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
