West Coast of the United States

The West Coast sits by the big ocean. It includes California, Oregon, and Washington. Some people also include Alaska and Hawaii.

The weather can change a lot. The north can be wet and rainy. The south is often dry.

Cold water in the sea helps keep the air cool.

Fog can also hide the shore. This makes the coast feel cool.

Many people live in big cities here. Los Angeles is a very large city. It has many people living there. The West Coast is a very special place.

The West Coast sits by the North Pacific Ocean. It usually means California, Oregon, and Washington. Some people also include Alaska and Hawaii.

The weather changes as you move. The north is often wet and rainy. The south is much drier. Cold ocean water helps keep the air cool. Thick fog can also hide the shore. This keeps the coast feeling cool even in summer.

Many people live in big cities here. California has many large cities. Los Angeles is a very big city. It has nearly four million people. San Diego and San Jose are also very large.

Other big cities include San Francisco, Seattle, and Portland.

Long ago, the first people arrived here. They crossed a land bridge to reach North America. Later, many explorers came to the area. In 1869, a new railroad joined the coast to the East.

The West Coast of the United States sits along the North Pacific Ocean. Most people use this name for three states: California, Oregon, and Washington. Some people also include Alaska and Hawaii in this group. For example, the U.S. Census Bureau counts all five states together. The area is part of the larger North American continent. It is a long stretch of land where the country meets the sea.

The weather changes depending on where you stand. The northern part near the Canada border has an oceanic climate. This means it gets a lot of rain, especially in winter. As you move south toward Mexico, the weather becomes Mediterranean. This type of climate is much drier. Cold water in the Pacific Ocean helps keep the air cool. Thick coastal fog often rolls in to shade the shore.

History began here a very long time ago. The first humans, called Paleo-Indians, arrived from Eurasia. They crossed a land bridge named Beringia many thousands of years ago. Later, different groups of people lived here and made trade routes. Eventually, explorers from Spain, Britain, France, and Russia arrived. The United States officially took control of these lands in the mid-1800s. In 1869, a huge railroad finally linked the coast to the East.

Many people live in the large cities along this coast. California has many of the biggest cities in the country. Los Angeles is very large with nearly four million people. San Diego and San Jose also have over one million residents each.

Other famous cities include San Francisco, Seattle, and Portland.

Today, the West Coast is known for its unique culture and politics. Most of these states tend to vote for the Democratic Party. In fact, four out of five West Coast states have voted Democratic in presidential elections since 1992. Many people in these states care deeply about climate change. A 2019 poll showed that 72% of adults there say it affects them. This shows how much the local environment matters to the people living there.

The West Coast of the United States is a major geographic region. It is the coastline where the Western United States meets the North Pacific Ocean. While definitions vary, the term usually refers to California, Oregon, and Washington. These are the three contiguous states along the Pacific. However, some groups use the term more broadly. The U.S. Census Bureau includes Alaska and Hawaii in this geographic division. Some dictionaries define the area more strictly from Washington down to California.

The history of this region began with the Paleo-Indians. These were the earliest known humans in the Americas. They arrived from Eurasia by crossing a land bridge called Beringia. This land bridge existed between 45,000 BCE and 12,000 BCE. Small groups of hunter-gatherers moved into Alaska following large animal herds. Between 16,500 BCE and 13,500 BCE, ice-free corridors opened along the coast. These paths allowed people to move through valleys and by sea. These early people became the ancestors of Alaska Natives and various Indigenous groups. They established complex trade routes and many different languages.

European explorers eventually arrived to colonize the area. These explorers came from Spain, Britain, France, and Russia. The United States officially incorporated the West Coast in the mid-1800s. The Oregon Territory was established in 1848. It was previously managed jointly by the U.S. and the United Kingdom. The Oregon Treaty of 1846 set its boundaries. California was ceded to the U.S. by Mexico in 1848 following the Mexican-American War. California became the 31st state in 1850. The Washington Territory split from Oregon in 1853. Oregon and Washington joined the Union in 1859 and 1889, respectively.

The climate of the West Coast changes significantly by location. The Northwestern edge near the Canada border has an oceanic climate. This area experiences moderate rainfall, especially during the winter. As you move south toward the Mexico border, the climate becomes Mediterranean. This region is much drier throughout the year. Coastal temperatures are often milder than inland areas during the summer. Cold currents in the Pacific Ocean help moderate these temperatures. Mountain ranges also block maritime air from moving deep inland. Coastal fog is very common and keeps the shoreline cool.

Large cities are central to the West Coast experience. California contains 16 of the 20 largest cities on the coast. Los Angeles is the most populous with 3,898,747 residents. San Diego follows with 1,386,932 people. San Jose also has over one million residents.

Other major urban centers include San Francisco, Seattle, and Portland.

Honolulu is the 13th largest city in the region, while Anchorage is the 17th. These cities create a diverse and crowded coastal environment.

Politically, the West Coast is often described as a "blue wall." This refers to the shared political values in the contiguous states. Most West Coast states have been dominated by the Democratic Party in recent history. Since 1992, four out of five West Coast states have voted Democratic in presidential elections. In 2022, Democrats controlled every West Coast seat in the U.S. House of Representatives.

This political strength is very high in the region. For example, 72% of adults in Pacific states say climate change affects their community. This is a higher percentage than any other region in the country.

The culture of the West Coast is shaped by its many different people. California has a distinctive Hispanic-American tone due to its Spanish and Mexican history. This influence is seen throughout the lower West Coast. The region also has significant Asian American populations. These populations are heavily concentrated in cities like San Francisco and Los Angeles. These cultural layers connect the West Coast to the broader history of the Americas and the Pacific.
