Weather in August

August, the last month of the summer in Etowah, is another hot month, with an average temperature fluctuating between 64.8°F (18.2°C) and 86.5°F (30.3°C).

Temperature

As Etowah steps into August, the average high-temperature holds at a still tropical 86.5°F (30.3°C), hinting at a minor fluctuation from the prior month. Etowah sees a major change from daytime highs, with the nighttime temperature dipping to a comfortable 64.8°F (18.2°C) on average during August.

Heat index

Throughout August, the heat index is calculated to be a sweltering 98.6°F (37°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
Given the heat index, its values are aligned with shaded sites and gentle winds. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
