Weather in August
Temperature
Welcoming August, Sellersville notes an average high-temperature of a still warm 82.4°F (28°C), nearly consistent with July's 84.9°F (29.4°C). In the month of August, the average low-temperature usually rests at a refreshing 64.2°F (17.9°C).Heat index
August's heat index is calculated to be a hot 87.8°F (31°C). Enduring exposure and ongoing activity could cause a sense of fatigue and subsequent heat cramps.Records show heat index calculations are tailored for shaded regions and mild winds. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', determines the feeling of heat when you account for the relative humidity. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
