Weather in August
Temperature
The advent of August reveals an average high-temperature of a moderately hot 85.6°F (29.8°C), showing minimal difference from the prior month. In August, Evanston experiences an average nighttime temperature of 65.7°F (18.7°C).Heat index
Throughout August, the heat index is evaluated at a torrid 96.8°F (36°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.Heat index determinations are made taking into account the shade and light air movements. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', measures the perceived warmth when incorporating the humidity present in the air. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
