Weather in August
Temperature
The shift into August reveals an average high-temperature of a still hot 90.7°F (32.6°C), closely mirroring July's climate. Old Union's average low-temperature for the month of August records at a pleasant 70.9°F (21.6°C).Heat index
During August, the heat index is estimated at a scorching 109.4°F (43°C). Mindful: Heat cramps and heat exhaustion are to be expected. Extended physical effort might result in heatstroke.Understand that the heat index values take into account shaded locations and mild winds. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', comes about by integrating the temperature readings with the humidity levels. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. 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.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
