Weather in August

The last month of the summer, August, is also a moderately hot month in Hartford, Tennessee, with an average temperature fluctuating between 61.5°F (16.4°C) and 85.3°F (29.6°C).

August's onset brings an average high-temperature of a still warm 85.3°F (29.6°C), showing a minute difference from July's 85.8°F (29.9°C). Hartford reports a sharp reduction in temperature during August, averaging at a refreshing 61.5°F (16.4°C) at night.

Heat index

For most parts of August, the heat index is appraised at a sweltering 95°F (35°C). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.
Know that the heat index computations account for shaded terrains and slight winds. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
