The last month of the summer, August, is another hot month in Carrollton, Virginia, with an average temperature fluctuating between 71.2°F (21.8°C) and 86.2°F (30.1°C).

Temperature

August brings a marginal elevation to a still hot 86.2°F (30.1°C) from July's 88°F (31.1°C) in Carrollton's average high-temperatures. Throughout August, an average low-temperature of 71.2°F (21.8°C) is expected.

Heat index

The heat index in August is computed to be a torrid 96.8°F (36°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.
In reference to the heat index, it's for places in shade and with a slight wind. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', gives a temperature feeling by integrating air temperature and humidity. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
