Weather in August
Temperature
The average high-temperature is a still hot 86.5°F (30.3°C) in August, hardly different from the 89.2°F (31.8°C) recorded in July. In Hartfield, an average nighttime temperature of 68.4°F (20.2°C) is expected during August.Heat index
The heat index for August is estimated at a fiery hot 98.6°F (37°C). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is the outcome of merging air's temperature and its humidity metrics. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

Conform to measures and uphold sun safety traditions. Warding off skin and eye harm is necessary. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. On sunny days, it's ideal to wear sunglasses that filter out UVA and UVB rays.
