Common questions

Congaree month by month: notes from the park service

• January: January sits in Congaree's mild winter, which the park says runs from November through February with afternoons reaching the mid-50s°F and nights that can dip below freezing. Snow is unusual but possible.
• February: February is the tail of Congaree's winter, mild by day in the mid-50s°F and sometimes freezing at night. Because the park drains a watershed about the size of Maryland, the park service notes that it does not have to rain at Congaree for the forest to flood; rain in upstate South Carolina is enough.
• March: March is when Congaree's mosquito season begins, the park service says (mid-spring to mid-fall), so pack repellent. Before you go, look at the flood gauges: almost 80% of the park lies in the Congaree River floodplain, which floods roughly ten times a year and can close trails and parts of the boardwalk.
• April: April falls in what the park calls one of the best times to visit Congaree: spring, March through May, when daily highs reach the mid to upper 70s°F and insects are generally not a problem. Showers are common, with about 3 inches of rain a month, and an occasional thunderstorm, so pack a light rain layer for the boardwalk and trails.
• May: May closes out Congaree's spring, with highs in the mid to upper 70s°F and around 3 inches of rain on average, by the park's seasonal guide. The park recommends spring and fall above all, when temperatures are most comfortable.
• June: June at Congaree means mosquitoes: the park service says visitors meet them from mid-spring to mid-fall, so bring insect repellent. Always carry water, for pets as well, and check for flooding first, since the floodplain forest floods roughly ten times a year and can close trails and parts of the boardwalk.
• July: July at Congaree is deep summer in South Carolina's Midlands: the park says temperatures regularly reach the upper 90s°F and often pass 100, and high humidity can push the heat index above 110. Nearby Columbia set a record of 113°F in 2012.
• August: 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.
• September: September starts Congaree's autumn, which the park counts among the best times to visit: average daily temperatures in the 70s°F, low humidity and roughly 3 inches of rain a month. Water levels are ideal for paddling Cedar Creek in the fall, and colours along the waterways peak between late October and early November.
• October: October at Congaree: the park service puts mosquito season at mid-spring to mid-fall, so bring repellent. Flooding is the bigger variable, as the river floodplain floods about ten times a year and can cover backcountry trails and sections of the boardwalk.
• November: In November, Congaree's flooding and its neighbours both matter. The park lies in the Congaree River floodplain, which floods about ten times a year, and with nearly 80% of the park in it, floods can shut backcountry trails and parts of the boardwalk; check the Cedar Creek and Congaree River gauges before you go.
• December: December at Congaree: the floodplain forest floods about ten times a year, the park service says, and with almost 80% of the park in the floodplain, high water can close backcountry trails and parts of the boardwalk. Check the Cedar Creek gauge (flood stage about 8 feet) and the Congaree River gauges before you go.
