Weather in August

The last month of the summer, August, is another tropical month in McFarland, Tennessee, with an average temperature ranging between max 86.5°F (30.3°C) and min 64.8°F (18.2°C).

Temperature

McFarland starts August with an average high-temperature of a still hot 86.5°F (30.3°C), a minor shift from July's 87.1°F (30.6°C). Despite soaring daytime temperatures, McFarland registers a consistent average low-temperature of 64.8°F (18.2°C) in August.

Heat index

The average heat index in August is computed to be a torrid 98.6°F (37°C). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially vital to children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
