Weather in August
Temperature
In Snellville, August's average high-temperature stands at a still tropical 89.1°F (31.7°C), closely related to the preceding month. Snellville's temperature in August lowers to a consistent average of 70.2°F (21.2°C) during the nights.Heat index
Throughout August, the heat index is appraised at an extremely hot 104°F (40°C). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.Heat index data is primarily for areas with shade and subjected to light winds. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', gives a temperature feeling by integrating air temperature and humidity. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. For effective sun eye protection, rely on sunglasses certified for UVA and UVB resistance.
