Weather in August
Temperature
The arrival of August records an average high-temperature of a still warm 82.4°F (28°C), closely related to the 83.1°F (28.4°C) observed in July. Virginia experiences an average low-temperature reading of 64.8°F (18.2°C) throughout August.Heat index
The heat index value for August is evaluated at a hot 89.6°F (32°C). If one continues to be active during exposure, it might cause tiredness and subsequent heat cramps.Research indicates the heat index considers values in shaded locales and with light winds. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values remain especially vital for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
