Weather in August
Temperature
Mount Vernon experiences an average high-temperature of a still hot 90.1°F (32.3°C) in August, subtly different from July's 91°F (32.8°C). Throughout August, Mount Vernon experiences a low-temperature average of 69.4°F (20.8°C).Heat index
During August, the heat index is evaluated at a scorching 107.6°F (42°C). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
