Weather in August

The last month of the summer, August, is another warm month in Oswego, Tennessee, with an average temperature varying between 61.9°F (16.6°C) and 84.7°F (29.3°C).

Temperature

An average high-temperature of a still moderately hot 84.7°F (29.3°C) marks August, exhibiting a close resemblance to the conditions in July. Oswego anticipates a pronounced temperature drop from daily highs during the nights of August, with an average low of 61.9°F (16.6°C).

Heat index

The heat index in August is calculated to be a sweltering 95°F (35°C). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. 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 'felt air temperature' or 'real feel', unifies temperature and humidity readings to offer a comprehensive feel of warmth. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
