August weather forecast
Smyrna, TN

Weather-wise, August follows July's example, maintaining the peak summer heat but with slightly shorter days. As the sun’s trajectory begins to lower, the town experiences a gradual, almost imperceptible decline in temperatures. Nonetheless, the humidity tends to elevate during August, leading to a sticky, sometimes stifling, atmosphere. The cloud coverage remains relatively low, allowing the sun’s rays to filter through in most parts of the day. But with a relatively high rainfall of 2.4" (61mm), even the peak summer could offer the surprising pleasantness of an occasional rainy day.

Temperature

August's onset records a minor alteration in the average high-temperature to a still tropical 88°F (31.1°C) from July's 88.7°F (31.5°C). Smyrna records an average nighttime low of 68.2°F (20.1°C) in August.

Heat index

The heat index value during August is evaluated at a fiery hot 102.2°F (39°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
When assessing, remember that heat index measurements are for light winds and shaded spots. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
