Weather in August
Temperature
An average high-temperature of a still warm 84.6°F (29.2°C) marks August in Henderson, Kentucky, exhibiting a close resemblance to the conditions in July. Henderson, during August, witnesses an average low-temperature of 66.2°F (19°C).Heat index
August's average heat index is evaluated at a very hot 95°F (35°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an estimation of the warmth sensation when considering humidity levels. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
