Weather in August
Temperature
Vermont's weather, upon August's arrival, documents an average high-temperature of a still moderately hot 82.9°F (28.3°C), nearly identical to the prior month. Vermont records an average nighttime low of 64.2°F (17.9°C) in August.Heat index
The heat index in August is computed to be a tropical 91.4°F (33°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.Heat index evaluations are typically in the context of light winds and shaded environments. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', determines the feeling of heat when you account for the relative humidity. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
