Weather in August
Temperature
The onset of August notes an average high-temperature of a still warm 81.1°F (27.3°C), subtly shifted from July's 82°F (27.8°C). During August, Webster experiences a consistent low-temperature average of 62.8°F (17.1°C).Heat index
The average heat index in August is appraised at a hot 86°F (30°C). Long-standing exposure and activity could induce a feeling of tiredness and lead to heat cramps.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful 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.
