Weather in August
Temperature
The introduction of August sees an average high-temperature of a moderately hot 84.6°F (29.2°C), hardly deviating from July. During August nights, Round Hill witnesses a consistent average temperature of 64°F (17.8°C).Heat index
During August, the heat index is estimated at a hot 93.2°F (34°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Heat index determinations are made taking into account the shade and light air movements. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a composite of temperature and humidity figures to convey how warm it feels. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
