Weather in August

August follows the summer trend in Hanahan with hot temperatures and significant rainfall, but it stands out with the most precipitation in the year leading up to 6.22" (158mm). The prolonged warm temperatures and high humidity might make outdoor activities less favourable in August compared to July. As the month advances, August paves the way for September, which experiences slightly lower temperatures and less rainfall. Despite the heat and humidity, it's still the tail-end of summer, ideal for taking advantage of the natural beauty and outdoor activities in Hanahan.

Temperature

The advent of August brings an average high-temperature of a still tropical 89.4°F (31.9°C), almost identical to the preceding month. Hanahan experiences an average temperature drop to a warm 75.4°F (24.1°C) during August nights.

Heat index

August's heat index is appraised at an extremely hot 107.6°F (42°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
