States with the Most Coastline

A coast, also known as a coastline, is where the land meets the sea or ocean. The coastline can also refer to where the land meets a lake. Coasts are dynamic and create essential ecosystems. They’re home to marine plants, animals, and insects. Coastlines also help humans understand natural events like weather and changing sea levels.

The United States has several coastlines: the East Coast, which runs along the Atlantic Ocean; the West Coast, which runs along the Pacific Ocean; the Gulf Coast, which runs along the Gulf of Mexico; the lake states, which includes the states with Great Lakes shoreline, and the Arctic Coast, which runs along the northern part of Alaska.

U.S. Coastal States

For obvious reasons, coastal states have more coastline than inland states such as Kansas or Nebraska. The U.S. has 30 coastal states with over 12,000 miles of ocean coastline.

The Atlantic Coast states are: Connecticut, Delaware, Georgia, Florida, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, North Carolina, Rhode Island, South Carolina, and Virginia. The Pacific Coast states are: Alaska, California, Hawaii, Oregon, and Washington. The Gulf Coast states are Alabama, Florida, Louisiana, Mississippi, and Texas. The Great Lakes states are: Illinois, Indiana, Michigan, New York, Ohio, Pennsylvania, and Wisconsin. The Arctic Coast has one state: Alaska.

Coastal cities are typically popular tourist destinations, ports of entry, and shipping ports. Coastal cities are home to a significant portion of the population. While coastal city residents enjoy views of the water and access to beach and water activities, they are at a higher risk of flooding, strong winds, and hurricanes (particularly in the Southeast). Some well-known coastal cities in the U.S. are New York City, New York; Boston, Massachusetts; San Francisco, California; and Miami, Florida.

Coastal states have unique coastlines. The beaches of Florida are different from the beaches in New Jersey and those in California. Some other coastlines are marshy, and some have cliffs rather than sandy beaches. The water will be different along each coastline as well both in color, temperature, and temperament. You’re going to find clearer waters in Miami than you are in Boston.
