The prolonged warm temperatures and high humidity might make outdoor activities less favourable in August compared to July.

Temperature

As August unfolds, the average high-temperature reaches a still tropical 89.4°F (31.9°C), hinting at a slight fluctuation from the previous month. An average low-temperature of 75.4°F (24.1°C) is recorded in the month of August in Hanahan.

Heat index

Throughout August, the heat index is appraised at an extremely hot 107.6°F (42°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.
When referencing the heat index, its values are suitable for shady environments and light breezes. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', integrates the air's temperature and its humidity to showcase the felt temperature by people. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
