Weather in August
Temperature
August observes an average high-temperature of a warm 84.6°F (29.2°C), marking an insignificant difference from July's 86.4°F (30.2°C). Dearborn records an average low-temperature of 65.3°F (18.5°C) throughout the month of August.Heat index
August's average heat index is estimated at a fiery hot 95°F (35°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Stand by precautions and apply sun safety measures. Evading sunburn is of great importance. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
