The West Coast of the United States, also known as the Pacific Coast, Pacific states, and the western seaboard, is the coastline
along which the Western United States
meets the North Pacific Ocean
. The term typically refers to the contiguous U.S.
states of California
, and Washington
, but sometimes includes Alaska
, especially by the United States Census Bureau
as a U.S. geographic division.
With the exclusion of Alaska, the Democratic Party
has dominated West Coast politics in contemporary history, with the states consistently voting for Democrats in elections at various levels. Four out of five West Coast states have voted for Democrats in presidential elections since 1992
, three of which have done so since 1988
There are conflicting definitions of which states comprise the West Coast of the United States, but the West Coast always includes California
, and Washington
as part of that definition. Under most circumstances, however, the term encompasses the three contiguous states and Alaska
, as they are all located in North America. For census purposes, Hawaii
is part of the West Coast, along with the other four states.
'' refers to the North American region as part of the Pacific Coast, including Alaska and British Columbia
. Although the encyclopedia acknowledges the inclusion of Hawaii in some capacity as part of the region, the editors wrote that "it has little in common geologically with the mainland states."
Several dictionaries offer different definitions of the West Coast. Lexico
restricts the West Coast's definition to "the western seaboard of the U.S. from Washington to California."
However, Macmillan Dictionary
provides a less specific definition as "the western coast of the U.S., along the Pacific Ocean."
As for the Cambridge Dictionary
, the West Coast is "the area of the Pacific coast in the U.S. that includes California."
The history of the West Coast
begins with the arrival of the earliest known humans of the Americas, Paleo-Indians
, crossing the Bering Strait
into North America over a land bridge, Beringia
, that existed between 45,000 BCE and 12,000 BCE (47,000–14,000 years ago). Small isolated groups of hunter-gatherer
s migrated alongside herds of large herbivores
far into Alaska
. Between 16,500 BCE and 13,500 BCE (18,500–15,500 years ago), ice-free corridors developed along the Pacific coast
and valleys of North America and possibly by sea.
, indigenous peoples of the Pacific Northwest Coast
, and California indigenous peoples
eventually descended from the Paleo-Indians
. They developed various languages and established trade routes
Later, Spanish, British, French, Russian, and American explorers and settlers began colonizing the area
The West Coast of the United States has an oceanic climate
in its Northwestern, Northern, and Eastern edge towards the U.S.-Canada border, but from the California border towards the U.S.-Mexico border the climate is mediterranean
. The coastline sees significantly mild temperatures when compared to the inland areas during summer. In far Northern California there is a difference of 17 °C (30 °F) between Eureka
and Willow Creek
in spite of only 25 miles (40 km) separating the locations and Willow Creek being located at a elevation. Slightly narrower fluctuations can be seen all through the coastline, and could partially be explained by the cold currents in the Pacific Ocean moderating coastal temperatures and the mountain ranges blocking the maritime air from moving farther inland than its foothills during summer. Coastal fog
is also prevalent in keeping shoreline temperatures cool. This does not only occur in the San Francisco Bay Area
, but it also affects Santa Monica
in Los Angeles
, Southern California
, with very little yearly temperature differences but with cool summers similar to those expected in Northern Europe
. A short journey inland and summer temperatures are comparable with the rest of the United States on the same latitudes, sometimes warmer due to prevailing winds from the Nevada
and Arizona hot desert climate
Government and politics
Ideology and party strength
In politics, the West Coast usually refers to the contiguous coastal states of California, Oregon, and Washington because of their similar political leanings. In 2017, ''The Oregonian
'' columnist David Sarasohn
described the West Coast as a "blue wall
" of shared values on immigration
, climate change
, and civil liberties
By 2016, the West Coast states legalized marijuana
after California voted
to do so.
According to a 2019 Pew Research Center
poll, 72% of adults in Pacific states said that "climate change is affecting their local community at least some," higher than in any other region in the country.
, the three states have voted for Democrats
in presidential elections without interruption, but Oregon and Washington also voted for the Democratic presidential candidate in 1988
Although the three states have reliably voted Democratic, no Democratic presidential candidate from any of the three states has won their party's nomination as of 2020.
In the 2010s, Democrats strengthened their political power along the West Coast. After winning a special election
for a seat in the Washington state senate in 2017, Democrats built a government trifecta
in all three West Coast states.
After the 2018 U.S. House of Representatives elections
, Democrats controlled all West Coast congressional districts except Washington's 3rd
, represented by a Republican
Even though Hawaii is not usually part of the West Coast in the political definition, it has been a Democratic stronghold. Before achieving statehood in 1959, Hawaii became a state favorable to Democrats to the point that they sought statehood for the territory. However, Southern Democrats
opposed the move because it would mean additional votes against their region on several issues.
Since achieving statehood, Hawaii consistently voted for Democrats in presidential elections, except in 1972
, the Democratic Party
unseated the lone Republican
in the Hawaii Senate and controlled all seats in the state's upper house, which had not occurred anywhere in the country since 1980.
Dissimilar to the rest of the West Coast, Alaska has been a reliable state for Republicans in presidential elections. Since achieving statehood, Alaska has voted for the Democratic presidential candidate only once in 1964
. In 1960
, the state narrowly voted for Republican Richard Nixon
over Democrat John F. Kennedy
and had voted for Republicans uninterrupted since 1968
Presidential election history
*Bold denotes election winner
According to the 2019 population estimates from the United States Census Bureau, 16 of the 20 largest cities on the West Coast exist in California. Los Angeles
, San Diego
, and San Jose
lead the West Coast in population with more than a million people in each city, with Los Angeles being nearly three times the size of San Diego's population. Behind four California cities, Seattle
are respectively fifth and sixth in population. Hawaii's capital, Honolulu
, is the 13th largest city, and Alaska's largest city, Anchorage
, is 17th on the West Coast.
Since the West Coast has been populated by immigrants and their descendants more recently than the East Coast, its culture is considerably younger. Additionally, its demographic composition underlies its cultural difference from the rest of the United States. California's history first as a major Spanish colony, and later Mexican territory, has given the lower West Coast a distinctive Hispanic American tone, which it also shares with the rest of the Southwest. Similarly, two of the three cities in which Asian Americans have concentrated, San Francisco and Los Angeles, are located on the West Coast, with significant populations in other West Coast cities. San Francisco's Chinatown
, the oldest in North America, is a noted cultural center.
The West Coast also has a proportionally large share of green cities
within the United States, which manifests itself in different cultural practices such as bicycling and organic gardening.
In the Pacific Northwest
, Portland and Seattle are both considered among the coffee capitals of the world. While Starbucks
originated in Seattle, both cities are known for small-scale coffee roasters and independent coffeeshops. The culture has also been significantly shaped by the environment, especially by its forests, mountains, and rain. This may account for the fact that the Northwest has many high-quality libraries and bookshops (most notably Powell's Books
and the Seattle Central Library
) and a "bibliophile soul". The region also has a marginal, but growing independence movement based on bioregionalism
and a Cascadian
The Cascadian flag
has become a popular image at Seattle Sounders
and Portland Timbers
Alaska is widely known for its outdoors and its inhabitants engage in a range of activities which are unique to the state. Some of these activities can be experienced through the state's annual events, such as the Iron Dog
snowmobile race from Anchorage
and on to Fairbanks
. Other events include the World Ice Art Championships
(Fairbanks) and the Sitka Whalefest (Sitka
