Weather in July

As the middle of the year approaches, Shelbyville fully embarks on its summer journey, marked by July as its hottest month. The swift increase in temperature is coupled with an apparent decrease in overall wind speed. A peak temperature of about 87.3°F (30.7°C) is experienced in this period. Although the summer sun dominates the sky, several refreshing showers provide a welcome respite from the heat.

Temperature

July, noted for its average high-temperature of 87.3°F (30.7°C) and an average low-temperature of 67.8°F (19.9°C), is considered the warmest month in Shelbyville.

Heat index

The average heat index in July is computed to be a torrid 102.2°F (39°C). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a composite of temperature and humidity figures to convey how warm it feels. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
