Weather in August
Temperature
Norcross, Georgia, starts August with an average high-temperature of a still tropical 89.4°F (31.9°C), a minor shift from July's 90.7°F (32.6°C). An average low-temperature of 70.3°F (21.3°C) is common in Norcross, Georgia, during the nights of August.Heat index
In August, the average heat index is calculated to be an extremely hot 104°F (40°C). Undertake additional safety actions, risk of heat cramps and heat exhaustion is significant. Persistent activity may induce heatstroke.In terms of the heat index, values are set with light wind and shade conditions in mind. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', takes into account both air temperature and humidity to illustrate what people actually feel. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
