Weather in August
Temperature
August's arrival brings an average high-temperature of a still tropical 88.3°F (31.3°C), slightly deviating from July's 89.6°F (32°C). North Charleston witnesses an average low-temperature of 76.3°F (24.6°C) throughout the month of August.Heat index
The heat index for August is estimated at a scorching 104°F (40°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

The month with the most rainfall is August, when the rain falls for 22.7 days and typically aggregates up to 4.29" (109mm) of precipitation.Snowfall

May through August, with an average maximum UV index of 7, are months with the highest UV index. A UV Index reading of 6 to 7 represents a high threat to health from unsafe exposure to UV radiation for the ordinary person.Note: The maximum UV index of 7 during August translates into these guidelines:
Avoid overexposure. Fair-skinned individuals can burn in under 20 minutes. 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. Fend off the sun's harsh rays with appropriate clothing, a wide-brim hat, and UV-protective sunglasses.
