Weather in August
Temperature
Greenville's weather in August indicates an average high-temperature of a still hot 87.4°F (30.8°C), nearly consistent with the 88.5°F (31.4°C) of July. During August, the nighttime temperature averages of 67.1°F (19.5°C).Heat index
The average heat index in August is evaluated at a sweltering 102.2°F (39°C). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.Factoring in the heat index, values are geared towards shaded areas with light breezes. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. 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.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
