Weather in August
Temperature
August's onset sees an average high-temperature of a still hot 88.3°F (31.3°C), exhibiting a slight fluctuation from the previous month. Waynesboro's temperature in August lowers to a consistent average of 68°F (20°C) during the nights.Heat index
For most parts of August, the heat index is estimated at an extremely hot 104°F (40°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
