Weather in August
Temperature
July's transformation into August witnesses an average high-temperature of a still tropical 90.1°F (32.3°C), noting a minor change from the preceding month. Charleston's nighttime temperature during August is consistently averaged at an agreeable 71.1°F (21.7°C).Heat index
During August, the heat index is evaluated at a blistering 109.4°F (43°C). Vigilance: Heat cramps and heat exhaustion are likely. The likelihood of heatstroke increases with continued activity.It is essential to grasp that the heat index's numbers are for shade and light wind settings. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. 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.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
