Charleston

Charleston is the oldest and second-largest city in the U.S. state of South Carolina, the county seat of Charleston County, and the principal city in the Charleston–North Charleston–Summerville Metropolitan Statistical Area. The city lies just south of the geographical midpoint of South Carolina's coastline and is located on Charleston Harbor, an inlet of the Atlantic Ocean formed by the confluence of the Ashley and Cooper Rivers, or, as is locally expressed, "where the Cooper and Ashley Rivers come together to form the Atlantic Ocean." 

Founded in 1670 as Charles Town in honor of King Charles II of England, Charleston adopted its present name in 1783. It moved to its present location on Oyster Point in 1680 from a location on the west bank of the Ashley River known as Albemarle Point. By 1690, Charles Town was the fifth-largest city in North America, and it remained among the 10 largest cities in the United States through the 1840 census. With a 2010 census population of 120,083 (and a 2014 estimate of 130,113), current trends put Charleston as the fastest-growing municipality in South Carolina. The population of the Charleston metropolitan area, comprising Berkeley, Charleston, and Dorchester Counties, was counted by the 2014 estimate at 727,689 – the third-largest in the state – and the 78th-largest metropolitan statistical area in the United States. 

Known for its rich history, well-preserved architecture, distinguished restaurants, and mannerly people, Charleston has received a large number of accolades, including "America's Most Friendly " by Travel + Leisure in 2011 and in 2013 and 2014 by Condé Nast Traveler, and also "the most polite and hospitable city in America" by Southern Living magazine. 

According to the United States Census Bureau, the city has a total area of 127.5 square miles (330.2 km2), of which 109.0 square miles (282.2 km2) is land and 18.5 square miles (47.9 km2) is covered by water. The old city is located on a peninsula at the point where, as Charlestonians say, "The Ashley and the Cooper Rivers come together to form the Atlantic Ocean." The entire peninsula is very low, some is landfill material, and as such, frequently floods during heavy rains, storm surges, and unusually high tides. The city limits have expanded across the Ashley River from the peninsula, encompassing the majority of West Ashley as well as James Island and some of Johns Island. The city limits also have expanded across the Cooper River, encompassing Daniel Island and the Cainhoy area. North Charleston blocks any expansion up the peninsula, and Mount Pleasant occupies the land directly east of the Cooper River. 

The tidal rivers (Wando, Cooper, Stono, and Ashley) are evidence of a submergent or drowned coastline. There is a submerged river delta off the mouth of the harbor, and the Cooper River is deep, affording a good location for a port. 

Charleston has a humid subtropical climate (Köppen climate classification Cfa), with mild winters, hot, humid summers, and significant rainfall all year long. Summer is the wettest season; almost half of the annual rainfall occurs from June to September in the form of thundershowers. Fall remains relatively warm through November. Winter is short and mild, and is characterized by occasional rain. Measurable snow (≥0.1 in or 0.25 cm) only occurs several times per decade at the most, with the last such event occurring December 26, 2010.  However, 6.0 in (15 cm) fell at the airport on December 23, 1989, the largest single-day fall on record, contributing to a single-storm and seasonal record of 8.0 in (20 cm) snowfall.  

The highest temperature recorded within city limits was 104 °F (40 °C), on June 2, 1985, and June 24, 1944, and the lowest was 7 °F (−14 °C) on February 14, 1899, although at the airport, where official records are kept, the historical range is 105 °F (41 °C) on August 1, 1999 down to 6 °F (−14 °C) on January 21, 1985. Hurricanes are a major threat to the area during the summer and early fall, with several severe hurricanes hitting the area – most notably Hurricane Hugo on September 21, 1989 (a category 4 storm). Dewpoint in the summer ranges from 67.8 to 71.4 °F (20 to 22 °C). 

Charleston was hit by a large tornado in 1761, which temporarily emptied the Ashley River, and sank five offshore warships. 

The Charleston-North Charleston-Summerville Metropolitan Statistical Area currently consists of three counties: Charleston, Berkeley, and Dorchester. As of the 2013 U.S. Census, the metropolitan statistical area had a total population of 712,239 people. North Charleston is the second-largest city in the Charleston-North Charleston-Summerville Metropolitan Statistical Area and ranks as the third-largest city in the state; Mount Pleasant and Summerville are the next-largest cities. These cities combined with other incorporated and unincorporated areas surrounding the city of Charleston form the Charleston-North Charleston Urban Area with a population of 548,404 as of 2010. The metropolitan statistical area also includes a separate and much smaller urban area within Berkeley County, Moncks Corner (with a 2000 population of 9,123). 

The traditional parish system persisted until the Reconstruction Era, when counties were imposed. Nevertheless, traditional parishes still exist in various capacities, mainly as public service districts. The city of Charleston which was originally defined by the limits of the Parish of St. Philip and St. Michael, now also includes parts of St. James' Parish, St. George's Parish, St. Andrew's Parish, and St. John's Parish, although the last two are mostly still incorporated rural parishes.
