August, the last month of the summer in Grady, is another tropical month, with temperature in the range of an average high of 86.5°F (30.3°C) and an average low of 64.8°F (18.2°C).

Temperature

August's arrival brings an average high-temperature of a still hot 86.5°F (30.3°C), slightly deviating from July's 87.1°F (30.6°C). Grady's average nighttime temperature descends significantly from the day's peak in August, settling at a refreshing 64.8°F (18.2°C).

Heat index

August's mean heat index is calculated to be a fiery hot 98.6°F (37°C). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular significance for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.
