Dewey Beach is an incorporated coastal town in Sussex County, Delaware, United States. According to the 2010 census, the population of the town is 341, an increase of 13.3% over the previous decade. It is part of the Seaford, Delaware Micropolitan Statistical Area. While not as extreme as spring-break locales such as Panama City Beach or Cancun, Dewey Beach has developed a reputation as a wild summer "party town", and is particularly popular in the Washington, D.C., Baltimore, Philadelphia, and Wilmington areas. Incorporated in 1981, the town lies on a small strip of land between the Atlantic Ocean and Rehoboth Bay, is about one mile long and only two blocks wide. Despite its small size and low year-round population of about 300, it is not uncommon for 30,000 to descend upon the town during summer weekends. Numerous bars and rock clubs line Coastal Highway (Delaware Route 1), the town's main street. Further down Coastal Highway is Ruddertowne, home to more bars and clubs. Notwithstanding its reputation as a magnet for partygoers, Dewey Beach is also a popular family resort spot, particularly because of its wide, sandy beaches, and many hotels, cottages, and condominiums may be found.
