Weather in July

July, the same as June, is a moderately hot summer month in Highland, Illinois, with an average temperature varying between 67.6°F (19.8°C) and 84.9°F (29.4°C).

Temperature

Temperature readings reach their annual highs in July, averaging 84.9°F (29.4°C) and a minimum average of 67.6°F (19.8°C).

Heat index

During July, the heat index is calculated to be a sweltering 96.8°F (36°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.
The standards for the heat index are set for locations in shade and under light breezes. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'real feel' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
