Bring your family and Visit Washington DC
Washington, the capital of the United States, is located in and coterminous (as of 1878) with the District of Columbia, a federally owned enclave surrounded on three sides by Maryland and across the Potomac River from Arlington and Fairfax counties, Va. The city is the center of a metropolitan area that is the eighth most populous in the country. The population of the city proper is 637,651 (1980), and that of the metropolitan area, 3,060,240. Washington is divided along a north-south axis by Rock Creek, historically a barrier to east-west movement. Additions to the city's total land area--at present 179 sq km (69 sq mi)--have been made by adding landfill along the shores of the Potomac.
Washington has a temperate midlatitude climate with mean temperatures of 3 deg C (37 deg F) in January and 26 deg C (79 deg F) in July. Summers are hot and humid, and yearly precipitation totals nearly 1,016 mm (40 in).
