Weather in July
Temperature
In Harpers Mill, the month of July is known for its highest average temperatures, reaching a high of 85.5°F (29.7°C) and a low of 70.3°F (21.3°C).Heat index
July's average heat index is computed to be a torrid 95°F (35°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Bear in mind that the heat index values are determined for shaded areas and light breezes. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
