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.Charleston had an estimated population of 134,385 in 2016.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).The dewpoint in June to August ranges from 67.8 to 71.4 °F (19.9 to 21.9 °C). Census, the metropolitan statistical area had a total population of 712,239 people.The Westo had made enemies of nearly every other tribe in the region, however, and the English turned on them in 1679.Destroying them by 1680, the settlers were able to use their improved relations with the Cusabo and other tribes to trade, recapture runaway slaves, and engage in slaving raids of Spanish-allied areas.
On December 7, 1710, the Lords Proprietors decided to separate the Province of North Carolina from Charles Town's government, although they continued to own and control both regions.(The original site is now commemorated as Charles Towne Landing.) Not only was this location more defensible, but it also offered access to a fine natural harbor which accommodated trade with the West Indies.The new town was the 5th-largest in North America by 1690.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.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.Charleston Harbor runs about 7 miles (11 km) southeast to the Atlantic with an average width of about 2 miles (3.2 km), surrounded on all sides except its entrance.
