Weather in August
Temperature
As July transitions into August, Upper Fairmount records an average high-temperature of a still moderately hot 81.9°F (27.7°C), showing a gentle shift from the preceding month. Upper Fairmount's nocturnal average in August closely mirrors its daytime temperatures, settling at a still moderately hot 74.1°F (23.4°C).Heat index
For August, the heat index is calculated to be a hot 87.8°F (31°C). If one sustains activity during exposure, it could lead to a sense of fatigue, with a chance of heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. 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 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant 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.
