US States With the Most Coastline

With a coastline stretching across 54,563 km, Alaska is the US state with the longest coastline.

The coastline is the length of land bordering the sea or ocean. Measuring the length of a coastline is a complex process as coastlines are usually highly indented. The length also keeps changing due to the action of tides, sea levels, volcanic activities, and flooding.
Every coastal country in the world has one or more coastlines while landlocked countries lack coastlines. The United States has the eighth longest coastline among the countries of the world. It has a coastline of 95,471 miles. There are more than 15 states in the United States with coastlines exceeding 1,000 miles.

Coastline Of Alaska

Alaska has 33,904 miles of coastline, the longest in the United States. The state is bordered by the Arctic Ocean to the north, the Bering Sea to the west, and the Pacific Ocean to the south.

Coastline Of Florida

The state of Florida is second on this list. It has a coastline of 8,436 miles on the Atlantic Ocean and the Gulf of Mexico. Florida's coastline is known for its stunning beaches that attract millions of tourists to the state each year.

Coastline Of Louisiana

Louisiana is bordered by the Gulf of Mexico to the south. The state's coastline stretches for 7,721 miles. Unfortunately, human activity and rising sea levels have heavily degraded the coastline. Louisiana is currently losing land at a rate of 25 square miles per year.

Coastline Of Hawaii

Hawaii is home to one of the most recently-formed coastlines in the US since the islands of Hawaii were formed by volcanic activity, and the volcanoes in the region continue to remain active. Of the numerous islands that make up the state, the island of Hawaii, or Big Island, has the longest coastline. The total length of the state's coastline is 1,052 miles.

Benefit Of Coastlines

Countries with long coastlines experience a lot of economic benefits. Longer coastlines mean more area is available for fishing activities. An extensive coastline also signifies a large area for offshore oil exploration. They also have more beaches or longer waterfront areas that serve to attract tourists. Coastlines also provide a perfect location for the establishment of marine parks.
