A Mediterranean climate ( / ˌ m ɛ d ɪ t ə ˈ r eɪ n i ən / MED -ih-tə- RAY -nee-ən ), also called a dry summer climate , described by Köppen as Cs , is a temperate climate type that occurs in the lower mid-latitudes (normally 30 to 44 north and south latitude). Such climates typically have dry summers and wet winters, with summer conditions being hot and winter conditions typically being mild. These weather conditions are typically experienced in the majority of Mediterranean-climate regions and countries, but remain highly dependent on proximity to the ocean, altitude and geographical location.
116-772: The Eureka Inn in Eureka , California, United States, is a four-story, 104-room Elizabethan Tudor Revival architectural style hotel, which opened in 1922. In February 1982, the structure was listed on the National Register of Historic Places . In 2004, the inn was closed after tax defaults by its owner. In 2008, Libo Zhu purchased the Inn for $ 2.75 million and began a program of refurbishment. The Inn reopened in May 2010, with renovation work continuing for another decade until completion in 2020. The hotel opened in 1922, coinciding with
232-423: A 6.5 magnitude earthquake occurred about 33 miles (53 km) off shore from Eureka. After two seconds, it became a violent "jumper", making objects fly; the mostly vertical shocks from the ground led to broken windows in shops, overturned shelving in homes and stores, and damage to architectural detail on a number of historic buildings. Local hospitals treated mostly minor related injuries, and electrical power
348-891: A Csb climate because of its location inside the Alborz mountains . Winters in this zone are rainy and can be mild to chilly. Some locales in this zone experience some amount of snowfall, while others do not. Csb climates are found in northwestern Iberian Peninsula (namely Galicia and the Norte region and west coast of Portugal ), in coastal Northern California , in the Pacific Northwest (namely western Washington , western Oregon and southern portions of Vancouver Island in British Columbia ), in central Chile , in parts of southern Australia and in sections of southwestern South Africa . A few locations close to

Temperatures during winter only occasionally fall below
580-673: A burgeoning cottage industry of hand-made creations, from glassware to wood-burning stoves, and a large variety of locally created art. Eureka's founding and livelihood was and remains linked to Humboldt Bay, the Pacific Ocean, and related industries, especially fishing. Salmon fisheries sprang up along the Eel River as early as 1851, and, within seven years, 2,000 barrels of cured fish and 50,000 pounds (23,000 kg) of smoked salmon were processed and shipped out of Humboldt Bay annually from processing plants on Eureka's wharf. In 1858,

Eureka is the largest city of the Eureka-Arcata-Fortuna Micropolitan Area ,
7888-407: The domestic timber market, which caused increased shipping to foreign markets. The log trade with Japan and other Pacific Rim nations increased. Despite many rumors to the contrary, little of this wood returned to U.S. markets. In 1989, the U.S. changed log export laws, permitting lower-cost timber from public lands to be exported as raw logs overseas to help balance the federal budget. After 1990,
8004-422: The early 1900s, shipment of products occurred by trucks, trains, and ships from Eureka, Humboldt Bay, and other points in the region, but Eureka remained the busy center of all this activity for over 120 years. These factors and others made Eureka a significant city in early California state history. A bustling commercial district with ornate Victorian-style buildings rose in proximity to the waterfront, reflecting
8120-609: The entire coastline of Humboldt Bay, stretching inland to the mountains. The Wiyot people are particularly known for their basketry and fishery management. An extensive collection of intricate basketry of the area's indigenous groups exists in the Clarke Historical Museum in Old Town Eureka . The Yurok people share linguistic and cultural practices with the Wiyot people, and their traditional territory
8236-486: The first immigrants who arrived as prospectors were also lumbermen, and the vast potential for industry on the bay was soon realized, especially as many hopeful gold miners realized the difficulty and infrequency of striking it rich in the mines. By 1854, after only four years since the founding, seven of nine mills processing timber into marketable lumber on Humboldt Bay were within Eureka. A year later, 140 lumber schooners operated in and out of Humboldt Bay moving lumber from
8352-477: The first of many ships built in Eureka was launched, beginning an industry that spanned scores of years. The bay is also the site of the West Coast's largest oyster farming operations, which began its commercial status in the nineteenth century. Eureka is the home port to more than 100 fishing vessels (with an all-time high of over 400 in 1981) in two modern marinas which can berth approximately 400 boats within
8468-666: The first safe land route between San Francisco and Eureka for people to venture to the Redwood Empire. As a result, Eureka's population of 7,300 swelled to 15,000 within ten years. By 1922, the Redwood Highway was completed, providing for the first reliable, direct overland route for automobiles from San Francisco. By 1931, the Eureka Street Railway operated fifteen streetcars over twelve miles (19 km) of track. Eureka's transportation connection to
8584-557: The freezing point and snow is generally seldom seen. Summer temperatures can be cool to very hot, depending on the distance from a large body of water, elevation, and latitude, among other factors. Strong winds from inland desert regions can sometimes boost summer temperatures up, quickly increasing the risk of wildfires . Notable exceptions to the usual proximity from bodies of water, thus featuring extremely high summer temperatures and cooler winters, include south-eastern Turkey and northern Iraq ( Urfa , Erbil ), surrounded by hot deserts to
8700-444: The global log market declined, and exports fell at the same time as Pacific Northwest log prices increased; leading buyers to seek less expensive logs from Canada and the southern United States . Debate continues among four stakeholders: timber owners, domestic processors, consumers and communities, on the impact of log export on the local economy. During the span of 1991 to 2001, timber harvest peaked in 1997. The local timber market
8816-478: The great prosperity experienced during this era. Hundreds of these Victorian homes remain today, of which many are totally restored and a few have always remained in their original elegance and splendor. The representation of these homes in Eureka, grouped with those in nearby Arcata and the Victorian village of Ferndale , are of considerable importance to the overall development of Victorian architecture built in
8932-647: The inn closed. In September 2008, Southern California businessman, Libo Zhu, purchased the inn for $ 2.75 million. His business plan, reviewed by the Greater Eureka Chamber of Commerce, suggested that he has "ambitious" plans to honor the inn's "integrity as a historic hotel." After refurbishment, Zhu reopened the inn in May 2010. Architectural details include the use of differing roof forms and "visually stunning textured elevations", which are highlighted by stucco and half-timbering. The 93,000 sq ft (8,600 m) hotel, which fully occupies
9048-706: The interior of northern California west of the Sierra Nevada , along the Wasatch Front in Utah , and inland areas of southern Oregon west of the Cascade Mountains . Southern California's coasts also experience hot summers due to the shielding effect of the Channel Islands . However, unshielded areas of that coastline can have warm-summer Mediterranean climates with hot-summer areas just
9164-454: The interior rooms and public areas needed updating and remodeling to be made again ready for the public. The inn appears extensively in the 2018 film An Evening with Beverly Luff Linn , under the name of The Moorhouse Hotel. Both the exterior and interior were used in the film. Eureka, California Eureka ( / j ʊ ˈ r iː k ə / yuurr- EE -kə ; Wiyot : Jaroujiji ; Hupa : dahwilahłding ; Karok : Uuth )
9280-607: The largest urban settlement on the Pacific Coast between San Francisco and Portland. This area is similar to what the U.S. Census officially defines as the Eureka UC (urban cluster), which is a "densely settled core of census tracts and/or census blocks that meet minimum population density requirements, along with adjacent territory containing non-residential urban land uses as well as territory with low population density included to link outlying densely settled territory with
9396-528: The latter decades of the twentieth century. Today, the major industries are tourism, timber (in value), and healthcare and services (in number of jobs). As a part of the Emerald Triangle , Eureka is known for the sale of cannabis and as a center for cannabis tourism . Major employers today in Eureka include the following governmental entities: College of the Redwoods , The County of Humboldt, and
9512-501: The lowest temperature seen in the year (most often occurring at night) is only a similarly moderate 29 °F (−1.7 °C), yielding a very short and mild temperature range of about 50 °F (28 °C) throughout the year. Additionally, Eureka remains the only city on the West Coast of the continental United States to have never recorded a temperature of 90 °F (32.2 °C). Temperatures drop to freezing or below only on
9628-557: The lowest were in 2001 with 9.4 million lb (4.3 million kg). After 1990 regulatory, economic, and other events led to a contraction of the local commercial fleet. In 1991, the Woodley Island marina opened, providing docking facilities for much of Eureka's commercial and recreational fleet. Many species are considered to be overfished. Recreational fishing has increased over time. Fifty percent of recreational fishermen using local boats are tourists from outside
9744-432: The lowland areas, temperatures which can sometimes prohibit the growth of typical cold-sensitive Mediterranean plants. Some Spanish authors opt to use the term 'continental Mediterranean climate' ( Clima Mediterráneo Continentalizado ) for some regions with lower temperatures in winter than the coastal areas, but Köppen's Cs zones show no distinction as long as winter temperature means stay above freezing. Additionally,
9860-487: The matriarch of a successful timber family in the county, purchased a controlling interest in the hotel and a process of modernization began. After Barnum's death in 1993, John Biord purchased her shares from her estate, and also purchased the remaining shares to secure full ownership of the property. However, in 2002 the Internal Revenue Service placed a lien on the inn due to unpaid taxes, and in 2004
9976-422: The median income for a family was $ 33,438. Males had a median income of $ 28,706 versus $ 22,038 for females. The per capita income for the city was $ 16,174. About 15.8% of families and 23.7% of the population were below the poverty line, including 29.6% of those under the age of 18 and 11.1% of those 65 and older. The 2010 United States Census reported that Eureka had a population of 27,191. The population density
10092-483: The mills to booming cities along the Pacific coast. By the time the charter for Eureka was granted in 1856, busy mills inside the city had a daily production capacity of 220,000 board feet. This level of production, which would grow significantly and continue for more than a century, secured Eureka as the "timber capital" of California. Eureka was at the apex of rapid growth of the lumber industry because of its location between huge coast redwood forests and its control of
10208-437: The nation. The magnificent Carson Mansion on 2nd and M Streets is perhaps the most spectacular Victorian in the nation. The home was built between 1884 and 1886 by renowned 19th-century architects Newsom and Newsom for lumber baron William M. Carson. This project was designed to keep mill workers and expert craftsman busy during a slow period in the industry. Old Town Eureka , the original downtown center of this busy city in
10324-470: The opening of the Redwood Highway between Eureka and San Francisco. A large property for those times, the Eureka Inn was the premier full-service lodging between San Francisco and Portland, Oregon . Though it housed many thousands of visitors (including US presidents and royalty) from all over the world during its first several decades, the hotel began to show the effects of time. In 1960 Helen Barnum,
10440-654: The population) lived in households, 1,434 (5.3%) lived in non-institutionalized group quarters, and 449 (1.7%) were institutionalized. There were 11,150 households, out of which 2,891 (25.9%) had children under the age of 18 living in them, 3,554 (31.9%) were opposite-sex married couples living together, 1,449 (13.0%) had a female householder with no husband present, 710 (6.4%) had a male householder with no wife present. There were 1,161 (10.4%) unmarried opposite-sex partnerships , and 146 (1.3%) same-sex married couples or partnerships . 3,971 households (35.6%) were made up of individuals, and 1,183 (10.6%) had someone living alone who
10556-408: The population. There were 10,957 households, out of which 25.8% had children under the age of 18 living with them, 34.8% were married couples living together, 14.0% had a female householder with no husband present, and 46.3% were non-families. 35.3% of all households were made up of individuals, and 11.8% had someone living alone who was 65 years of age or older. The average household size was 2.26 and
10672-458: The primary city on the bay, Arcata 's proximity to developing supply lines to inland gold mines ensured supremacy over Eureka through 1856. "Eureka" received its name from a Greek word meaning "I have found it!" This exuberant statement of successful (or hopeful) gold rush miners is also the official motto of the State of California. Eureka is the only U.S. location to use the same seal as
10788-416: The primary port facilities. Loggers brought the enormous redwood trees down. Dozens of movable narrow gauge railroads brought trainloads of logs and finished lumber products to the main rail line, which led directly to Eureka's wharf and waiting schooners. By the 1880s, railroads eventually brought the production of hundreds of mills throughout the region to Eureka, primarily for shipment through its port. After
10904-530: The reason for this cooler type of Mediterranean climate. The other main reason for this cooler type is the altitude . For instance, Menton on the French coast has a Csa climate while Castellar, Alpes-Maritimes , the adjacent town just north of Menton, with an altitude between 100 and 1,382 m (328 and 4,534 ft), has a Csb climate instead. The village of Siah Bisheh in Northern Iran also has
11020-592: The recent effects of climate change . The native vegetation of Mediterranean climate lands must be adapted to survive long, hot summer droughts in summer and prolonged wet periods in winter. Mediterranean vegetation examples include the following: Many native vegetations in Mediterranean climate area valleys have been cleared for agriculture and farming. In places such as the Sacramento Valley and Oxnard Plain in California , draining marshes and estuaries combined with supplemental irrigation has led to
11136-677: The settlement of Eureka on its shore by the Union and Mendocino Exploring (development) companies. After the primary California Gold Rush in the Sierras , Humboldt Bay was settled with the intent of providing a convenient alternative to the long overland route from Sacramento to supply miners on the Trinity , Klamath and Salmon Rivers where gold had been discovered. Though the ideal location on Humboldt Bay adjacent to naturally deeper shipping channels ultimately guaranteed Eureka's development as
11252-505: The so-called "Mediterranean trinity" of major agricultural crops have traditionally been successfully grown ( wheat , grapes and olives ). As a result, these regions are notable for their high-quality wines, grapeseed/olive oils, and bread products. Under the Köppen climate classification , "hot dry-summer" climates (classified as Csa ) and "cool dry-summer" climates (classified as Csb ) are often referred to as just "Mediterranean". Under
11368-419: The south and mountains to the north. Those places routinely experience summer daily means of over 30 °C (86 °F) and daily highs above 40 °C (104 °F), while receiving enough rainfall in winter not to fall into arid or semi-arid classifications. As in every climatologic domain, the highland locations of the Mediterranean domain can present cooler temperatures in the summer and winter than
11484-495: The south coast of England such as Weymouth and Portland just scrape into this climate classification due to very low rainfall in July. A trend towards slightly drier summers during the 1971–2000 climate average period, meant that this classification previously extended slightly further to include a few other weather stations in southern England, such as Bognor Regis and Teignmouth . Rarer instances of this climate can be found in relatively small and isolated high altitude areas of
11600-468: The state for its seal. Incoming settlers began encroaching on Wiyot people by cutting off their access to ancestral sources of food in addition to the outright theft of their land. Fort Humboldt was established by the U.S. Army on January 30, 1853, to establish peaceful relations between Native Americans, gold-seekers and settlers, often at the expense of the life and liberty of the Native people. The fort
11716-564: The summer and migrates towards the equator during the winter. This is due to the seasonal poleward-equatorward variations of temperatures. The resulting vegetation of Mediterranean climates are the garrigue or maquis in the European Mediterranean Basin, the chaparral in California, the fynbos in South Africa , the mallee in Australia, and the matorral in Chile. Areas with this climate are also where
11832-537: The sun. Poleward extension and expansion of the subtropical anticyclone over the oceans bring subsiding air to the region in summer, with clear skies and high temperatures. When the anticyclone moves Equator-ward in winter, it is replaced by traveling, frontal cyclones with their attendant precipitation. During summer, regions of the Mediterranean climate are strongly influenced by the subtropical ridge which keeps atmospheric conditions very dry with minimal cloud coverage. In some areas, such as coastal California ,
11948-461: The temperature and rainfall pattern for a Csa or even a Csb climate can exist as a microclimate in some high-altitude locations adjacent to a rare tropical As ( tropical savanna climate with dry summers, typically in a rainshadow region, as in Hawaii). These have a favourable climate, with mild wet winters and fairly warm, dry summers. The Mediterranean forests, woodlands, and scrub biome
12064-702: The tropics, on Haleakalā Summit in Hawaii. In South America, Csc regions can be found along the Andes in Chile and Argentina. The town of Balmaceda, Chile is one of the few towns confirmed to have this climate. Small areas with a Csc climate can be found at high elevations in Corsica . In Norway, the small fishing village of Røstlandet , in Røst Municipality , above the Arctic Circle has
12180-543: The victims were primarily children, women, and elderly tribal members. Major Gabriel J. Rains , Commanding Officer of Fort Humboldt at the time, reported to his commanding officer that a local group of vigilantes had resolved to "kill every peaceable Indian – man, woman, and child." Although the perpetrators were known, they never faced any legal consequences. Remaining Wiyot people took refuge at Fort Humboldt, but they were not given adequate living accommodations, and so half of them died from starvation or exposure. In 2004,
12296-457: The western sides of continents. Csb zones in the Köppen system include areas normally not associated with Mediterranean climates but with Oceanic climates, such as much of the Pacific Northwest , much of southern Chile , parts of west-central Argentina , and parts of New Zealand . Additional highland areas in the subtropics also meet Cs requirements, though they, too, are not normally associated with Mediterranean climates. The same goes for
12412-476: The winter and summer due to higher evapotranspiration . Toward the polar latitudes, total moisture usually increases; for instance, the Mediterranean climate in Southern Europe has more rain. The rainfall also tends to be more evenly distributed throughout the year in Southern Europe, while in places such as Southern California , the summer is nearly or completely dry. In places where evapotranspiration
12528-410: The winter, with frost and snowfall almost unknown, whereas Tashkent has cold winters with annual frosts and snowfall; or, to consider summer, Seville experiences rather high temperatures in that season. In contrast, San Francisco has cool summers with daily highs around 21 °C (70 °F) due to the continuous upwelling of cold subsurface waters along the coast. Because most regions with
12644-554: The year for climate zones at such distances from coasts. In North America, areas with Csc climate can be found in the Olympic , Cascade , Klamath , and Sierra Nevada ranges in Washington, Oregon and California. These locations are found at high altitude nearby lower altitude regions characterized by a warm-summer Mediterranean climate ( Csb ) or hot-summer Mediterranean climate ( Csa ). A rare instance of this climate occurs in
12760-413: Was 1,881.3 inhabitants per square mile (726.4/km ). The racial makeup of Eureka was 21,565 (79.3%) White , 514 (1.9%) African American , 1,011 (3.7%) Native American , 1,153 (4.2%) Asian , 176 (0.6%) Pacific Islander , 1,181 (4.3%) from other races , and 1,591 (5.9%) from two or more races. There were 3,143 Hispanic or Latino people of any race (11.6%). The census reported that 25,308 people (93.1% of
12876-438: Was 2.0%; the rental vacancy rate was 3.7%. 11,251 people (41.4% of the population) lived in owner-occupied housing units and 14,057 people (51.7%) lived in rental housing units. The economic base of the city was founded on timber and fishing and supplying resources for the gold mining efforts further inland. Gold mining diminished quickly in the early years, and activities of timber and fishing have also diminished, especially in
12992-749: Was 65 years of age or older. The average household size was 2.27. There were 5,713 families (51.2% of all households); the average family size was 2.93. There were 5,431 residents (20.0%) under the age of 18, 3,102 (11.4%) aged 18 to 24, 8,021 (29.5%) aged 25 to 44, 7,422 (27.3%) aged 45 to 64, and 3,215 (11.8%) who were 65 years of age or older. The median age was 36.2 years. For every 100 females, there were 106.0 males. For every 100 females age 18 and over, there were 105.7 males. There were 11,891 housing units at an average density of 822.7 units per square mile (317.6 units/km ), of which 11,150 were occupied, of which 4,829 (43.3%) were owner-occupied, and 6,321 (56.7%) were occupied by renters. The homeowner vacancy rate
13108-543: Was also affected by the Pacific Lumber Company hostile takeover and ultimate bankruptcy. Local fisheries expanded through the 1970s and early 1980s. During the 1970s, Eureka fishermen landed more than half of the fish and shellfish produced and consumed in California. In 2010, between 100 and 120 commercial fishing vessels listed Eureka as homeport. The highest landings of all species were 36.9 million lb (16.7 million kg) in 1981 while
13224-411: Was commanded by Brevet Lieutenant Colonel Robert C. Buchanan of the U.S. 4th Infantry Regiment . These tensions between Native people and settlers eventually led to the massacre on Tuluwat Island in 1860. The attackers, who were thought to be composed primarily of Eureka businessmen, killed as many as 250 Wiyot people. The Wiyot men had left the island during their annual World Renewal Ceremony, so
13340-498: Was from July 1889 to June 1890 with 73.30 in (1,861.8 mm) and the driest from July 1976 to June 1977 with 17.56 in (446.0 mm). The greatest monthly precipitation was 23.21 in (589.5 mm) in December 2002. The greatest 24-hour precipitation was 6.79 in (172.5 mm) on December 27, 2002. However, historic 100-year dramatic weather events such as the Christmas Week flood of 1955 and, especially,
13456-573: Was out over a large area. Numerous natural gas leaks occurred, but no fires resulted. This was the largest recent earthquake since the April 25–26, 1992 sequence . It was followed on February 4, 2010, by a magnitude 5.9 earthquake which struck about 35 miles (56 km) northwest of the community of Petrolia and nearly 50 miles (80 km) west of Eureka. The shaking was felt within a 150-mile (240 km) radius, as far north as southern Oregon and as far south as Sonoma County . The largest recorded in
