Weather in August
Temperature
August's onset records a minor alteration in the average high-temperature to a still warm 83.1°F (28.4°C) from July's 85.3°F (29.6°C). Glenmar records an average low-temperature of 66.9°F (19.4°C) throughout the month of August.Heat index
The average heat index in August is computed to be a tropical 89.6°F (32°C). If one sustains activity during exposure, it could lead to a sense of fatigue, with a chance of heat cramps.Heat index values are typically calculated for conditions of shade and a light breeze. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', joins air temperature with relative humidity to produce a temperature perception for 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. 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 extremely significant for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
