Weather in August
Temperature
Amissville marks the start of August with an average high-temperature of a warm 84.9°F (29.4°C), hinting at a slight fluctuation from July's 87.6°F (30.9°C). Throughout the month of August, Amissville witnesses an average temperature of 64.6°F (18.1°C).Heat index
The heat index value for August is estimated at a tropical 93.2°F (34°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.For clarity, heat index numbers account for light winds and areas under shade. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
