Weather in August
Temperature
August's weather displays an average high-temperature of a moderately hot 85.8°F (29.9°C), slightly varied from July's 86.9°F (30.5°C). Oak Park witnesses a consistent average low-temperature of 65.8°F (18.8°C) throughout August.Heat index
For August, the heat index is computed to be a sweltering 96.8°F (36°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.Be advised, the heat index considers values for conditions in shade and with a light breeze. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. 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 particularly relevant to children. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
