Weather in August
Temperature
Mount Vernon's average high-temperature in August is a still moderately hot 84.7°F (29.3°C), marking an insignificant difference from the 85.6°F (29.8°C) of July. During August, Mount Vernon sees a mean low-temperature of 63.5°F (17.5°C).Heat index
Throughout August, the heat index is calculated to be a very hot 95°F (35°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Know that the heat index computations account for shaded terrains and slight winds. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

Sunshine

The months with the highest UV index are May through August, with an average maximum UV index of 6. A UV Index reading of 6 to 7 represents a high health risk from unsafe exposure to UV radiation for the ordinary person.Note: A daily high UV index of 6 in August leads to these guidelines:
Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. The Sun's UV radiation is at its strongest between the hours of 10 a.m. and 4 p.m. Minimize direct exposure to the sun during this period. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation.
