Weather in August
Temperature
The advent of August observes an average high-temperature of a still warm 81°F (27.2°C), nearly identical to July's 82.4°F (28°C). During the nights in August, Sudbury observes an average low-temperature of 62.2°F (16.8°C).Heat index
August's average heat index is calculated to be a tropical 86°F (30°C). With unrelenting exposure and activity, one might experience exhaustion, leading to potential heat cramps.Heat index details are generally centered around shaded locations and a mild breeze. 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 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
