Norfolk is an independent city in the Commonwealth of Virginia, United States. At the 2010 census, the population was 242,803; in 2015, the population was estimated to be 247,189 making it the second-most populous city in Virginia, behind neighboring Virginia Beach.
Norfolk is located at the core of the Hampton Roads metropolitan area, named for the large natural harbor of the same name located at the mouth of Chesapeake Bay. It is one of nine cities and seven counties that constitute the Hampton Roads metro area, officially known as the Virginia Beach-Norfolk-Newport News, VA-NC MSA. The city is bordered to the west by the Elizabeth River and to the north by the Chesapeake Bay.
As the city is bordered by multiple bodies of water, Norfolk has many miles of riverfront and bayfront property, including beaches on the Chesapeake Bay. It is linked to its neighbors by an extensive network of Interstate highways, bridges, tunnels, and three bridge-tunnel complexes—the only bridge-tunnels in the United States.
Norfolk has a humid subtropical climate with moderate changes of seasons. Spring arrives in March with mild days and cool nights, and by late May, the temperature has warmed up considerably to herald warm summer days. Summers are consistently warm and humid, but the nearby Atlantic Ocean often exercises a slight cooling effect on daytime high temperatures, but a slight warming effect on nighttime low temperatures (compared to areas farther inland).
