It receives an average of 44.52 inches (1,131 mm) of precipitation each year, with the wettest season being August.

South Dennis lies at the intersection of Route 47 (known as Delsea Drive) and Route 83.[9] A major infrastructure project that realigned Route 47 and added a traffic light was completed in July 2007 at a cost of $6.7 million.[11] Two county routes, County Route 628 and County Route 657, terminate shortly after entering South Dennis.[12][13]
