Weather in July
Temperature
In Cairo, Illinois, the highest average temperatures are observed in July, with a high of 88.2°F (31.2°C) and a low of 69.8°F (21°C).Heat index
In July, the heat index is appraised at a scorching 104°F (40°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', gives an indication of how one might feel in terms of heat after considering humidity. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. As body temperatures escalate without effective heat release, one might face dehydration threats.
