Weather in August
Temperature
Louisville experiences a minor change to a still moderately hot 84.2°F (29°C) in average high-temperature during August, closely reflecting July. In August, the recorded average low-temperature in Louisville, of 57.4°F (14.1°C), exhibits a significant fall from the daytime highs.Heat index
The heat index value for August is estimated at 84.2°F (29°C). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.For clarity, heat index numbers account for light winds and areas under shade. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important 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.
