Weather in August
Temperature
The average high-temperature in August, at a still hot 88°F (31.1°C), reveals a modest deviation from July's 89.2°F (31.8°C). In Cumming, the average low-temperature during the month of August is a pleasant 68.2°F (20.1°C).Heat index
During August, the heat index is estimated at a sweltering 100.4°F (38°C). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Rising body temperatures due to excess heat retention could signify impending heat disorders.

Stick with precautions and abide by sun safety procedures. Evading sunburn is essential. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Sun-related eye harm can be minimized with proper sunglasses offering UVA and UVB coverage.
