East Coast of the United States

The East Coast of the United States, also known as the Eastern Seaboard, the Atlantic Coast, and the Atlantic Seaboard, is the coastline along which the Eastern United States meets the North Atlantic Ocean. Regionally, the term refers to the coastal states and area east of the Appalachian Mountains that have shoreline on the Atlantic Ocean, from north to south, Maine, New Hampshire, Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Delaware, Maryland, Virginia, North Carolina, South Carolina, Georgia, and Florida.

Toponymy and composition

The place name "East Coast" derives from the idea that the contiguous 48 states are defined by two major coastlines, one at the western edge and one on the eastern edge. Other terms for referring to this area include the "Eastern ", "Atlantic Coast", and "Atlantic Seaboard".
The 14 states that have a shoreline on the Atlantic Ocean are, from north to south, Maine, New Hampshire, Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Delaware, Maryland, Virginia, North Carolina, South Carolina, Georgia, and Florida. In addition, Pennsylvania and the District of Columbia border tidal arms of the Atlantic. The states of Alabama, Mississippi, Louisiana, and Texas, as well as the territories of Puerto Rico, the US Virgin Islands, and Navassa Island have Atlantic coastline, but are not included in the definition.
Although Vermont and West Virginia have no Atlantic coastline, they are grouped with the Eastern Seaboard states because of their locations in New England and the Old South, and their history as part of the land base of the original Thirteen Colonies.

Colonial history

The original 13 colonies of Great Britain in North America all lay along the East Coast.
Two additional U.S. states on the East Coast were not among the original thirteen colonies: Maine and Florida. Florida's written history begins with the arrival of Europeans; the Spanish explorer Juan Ponce de León in 1513 made the first textual records. The state received its name from this Spanish conquistador, who called the peninsula La Pascua Florida in recognition of the verdant landscape and because it was the Easter season, which the Spaniards called Pascua Florida.
The Middle Colonies had been owned by the Dutch as New Netherland, until they were captured by the English in the mid-to-late 17th century.

Climate and physical geography

There are three basic climate regions on the East Coast according to the Köppen climate classification from north to south based on the monthly mean temperature of the coldest month :
The region from northern Maine south to northern Connecticut has a continental climate, with warm summers, and cold and snowy winters. The area from southern Connecticut south to southern North Carolina has a temperate climate, with long, hot summers and cool winters, while the area from southern North Carolina south to central Florida is subtropical, with hot and rainy summers, and mild and drier winters. Around south-central Florida southward has a tropical climate, which is frost free and is warm to hot all year.
Average monthly precipitation ranges from a slight late fall maximum from Massachusetts northward, to a slight summer maximum in the Mid-Atlantic states from southern Connecticut south to Virginia, to a more pronounced summer maximum from Cape Hatteras, North Carolina, southward along the Southeastern United States coast to Savannah, Georgia. The Florida peninsula has a sharp wet-summer/dry-winter pattern, with 60 to 70 percent of precipitation falling between June and October in an average year, and a dry, and sunny late fall, winter, and early spring.
Although landfalls are rare, the Eastern seaboard is susceptible to hurricanes in the Atlantic hurricane season, officially running from June 1 to November 30, although hurricanes can occur before or after these dates. Hurricanes Hazel, Hugo, Bob, Isabel, Irene, Sandy, and most recently Florence are some of the more significant storms to have affected the region.
The East Coast is a low-relief, passive margin coast. It has been shaped by the Pleistocene glaciation in the far northern areas in New England, with offshore islands such as Nantucket, Block Island, Fishers Island. From around northern New Jersey southward, the coastal plain broadens southwards, separated from the Piedmont region by the Atlantic Seaboard fall line of the East Coast rivers, often marking the head of navigation and prominent sites of cities. The coastal areas from Long Island south to Florida are often made up of barrier islands that front the coastal areas, with the long stretches of sandy beaches. Many of the larger capes along the lower East Coast are in fact barrier islands, like the Outer Banks of North Carolina and Cape Canaveral, Florida. The Florida Keys are made up of limestone coral and provide the only coral reefs on the US mainland.


In 2010, the population of the states which have shoreline on the East Coast was estimated at 112,642,503. New York City is both the largest city and the largest metropolitan area on the East Coast. The East Coast is the most populated coastal area in the United States.

The primary Interstate Highway along the East Coast is Interstate 95, completed in 2018, which replaced the historic U.S. Route 1, the original federal highway that traversed all East Coast states, except Delaware. By water, the East Coast is connected from Boston, Massachusetts to Miami, Florida, by the Intracoastal Waterway, also known as the East Coast Canal, which was completed in 1912. Amtrak's Downeaster and Northeast Regional offer the main passenger rail service on the Seaboard. The Acela Express offers the only high-speed rail passenger service in the Americas. Between New York and Boston the Acela Express has up to a 54% share of the combined train and air passenger market.
Some of the largest airports in the United States are located along the East Coast of the United States, such as John F. Kennedy International Airport in New York, Logan International Airport in Boston, Newark Liberty Airport in Newark, New Jersey, Philadelphia International Airport in Philadelphia, Baltimore–Washington International Airport near Baltimore, Washington-Dulles International Airport near Washington, D.C., Hartsfield International Airport in Atlanta, Miami International Airport in Miami, Charlotte Douglas International Airport in Charlotte, North Carolina, Tampa International Airport in Tampa and Orlando International Airport in Orlando, Florida.


As the first spot in the United States that immigrants arrived and the close proximity of Europe, the Caribbean, and Latin America, the East Coast is home to a diverse population and home to multi-cultures when compared to the rest of the USA. From the strong Latin culture in southern Florida and New York City, to the 200 year old Gullah culture of the low country coastal islands of Georgia and South Carolina, to the many historic cities in the Middle Atlantic where a strong English, German, Italian, Irish, and French culture are present, the East Coast is significantly more diverse than the rest of the United States. Chinatown in New York City and Little Havana in Miami are examples of such cultural centers in the bigger cities,.
The East Coast is home to much of the political and financial power of the United States, as well as the center for resort and travel destinations in the United States.
