Weather in August
Temperature
Byrnes Mill transitions into August recording an average high-temperature of a still tropical 86.5°F (30.3°C), closely aligning with the preceding month's temperature. Byrnes Mill's nighttime temperature during August is consistently averaged at a comfortable 67.5°F (19.7°C).Heat index
August's mean heat index is evaluated at a sweltering 98.6°F (37°C). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.Heat index determinations are made taking into account the shade and light air movements. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
