The last month of the summer, August, is also a hot month in South Hill, Virginia, with an average temperature fluctuating between 87.3°F (30.7°C) and 67.6°F (19.8°C).

With the onset of August, a modest change to a still hot 87.3°F (30.7°C) from July's 89.6°F (32°C) is noted in high-temperature. In the month of August, the average low-temperature usually rests at a refreshing 67.6°F (19.8°C).

Heat index

In August, the average heat index is evaluated at a fiery hot 100.4°F (38°C). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.
Heat index data is primarily for areas with shade and subjected to light winds. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', binds temperature metrics with humidity values to give a sense of the actual warmth. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to 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.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
