Weather in August
Temperature
The warmest month is August, with an average high-temperature of 81.1°F (27.3°C) and an average low-temperature of 54.3°F (12.4°C).Heat index
The heat index in August is estimated at 84.2°F (29°C). Ongoing exposure and activity could lead to a state of exhaustion, with a chance of heat cramps.Heat index determinations are made taking into account the shade and light air movements. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
