The last month of the summer, August, is also a moderately hot month in Mantua, Virginia, with an average temperature ranging between max 85.8°F (29.9°C) and min 66.9°F (19.4°C).

Temperature

Mantua experiences an average high-temperature of a warm 85.8°F (29.9°C) with the onset of August, subtly varied from July's 88°F (31.1°C). An average low-temperature of 66.9°F (19.4°C) marks the month of August.

Heat index

August's average heat index is calculated to be a torrid 95°F (35°C). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.
The heat index's values are generally associated with conditions in shade and light breezes. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to 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.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

Also note that objects like parasols or canopies might not provide complete sun protection.
