Congaree in August: what the park service says
August is part of Congaree's hottest and wettest stretch, June through August, when monthly rainfall averages about 4.5 inches and thunderstorms can build quickly. Humid air makes the heat feel worse than the thermometer shows, the park warns. Daily highs regularly reach the upper 90s°F and often pass 100. The park describes autumn, not summer, as the time when Cedar Creek water levels are ideal for a paddling trip, and recommends proper clothing and footwear for any backcountry stay.
