Weather in August
August, the last month of the summer in Greenville, is another hot month, with temperature in the range of an average high of 86.4°F (30.2°C) and an average low of 69.6°F (20.9°C).Temperature
August's beginning signals an average high-temperature of a still hot 86.4°F (30.2°C), barely different from July's 88°F (31.1°C). An average low-temperature of 69.6°F (20.9°C) marks the nights throughout August.Heat index
August's heat index is computed to be a sweltering 100.4°F (38°C). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', gauges the sensation of temperature factoring in the air's moisture content. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.

Guard oneself from overexposure. Defence against sun injury is vital. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
