Weather in August
Temperature
August's commencement in Shelbyville is accompanied by an average high-temperature of a still warm 84.9°F (29.4°C), diverging marginally from July's 85.8°F (29.9°C). An average low-temperature of 64.9°F (18.3°C) marks the nights throughout August.Heat index
In August, the heat index is calculated to be a torrid 95°F (35°C). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', offers an insight into how hot it feels when we factor in moisture content. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
