The last month of the summer, August, is also a hot month in Morgantown, Tennessee, with an average temperature ranging between min 64.6°F (18.1°C) and max 86.5°F (30.3°C).

Temperature

The transition into August is marked with an average high-temperature of a still tropical 86.5°F (30.3°C), showing an insignificant shift from July's 87.4°F (30.8°C). Nighttime temperatures exhibit a substantial dip from daytime highs during August, averaging at a refreshing 64.6°F (18.1°C).

Heat index

For most parts of August, the heat index is appraised at a fiery hot 98.6°F (37°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.
One should consider that heat index numbers are for shaded settings and light wind. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
