Weather in August
Temperature
Transitioning from July to August, Seabrook Island observes an average high-temperature of a still hot 88.7°F (31.5°C), differing subtly from the previous month. An average low-temperature of 76.1°F (24.5°C) is observed during August nights.Heat index
The heat index for August is calculated to be a blistering 105.8°F (41°C). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', gauges the sensation of temperature factoring in the air's moisture content. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

Adopt measures and apply sun safety strategies. Shielding from skin and eye damage is necessary. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
