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.

106-891: 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

Much of the Overberg in the southern Cape of South Africa , was once covered with renosterveld , but has likewise been largely converted to agriculture, mainly for wheat . In hillside and mountainous areas, away from the urban sprawls , ecosystems and habitats of native vegetation are more sustained and undisturbed. The fynbos vegetation in the South-western Cape in South Africa

There Chernykh erected barracks and five other structures, and grew vegetables, fruit, wheat, and other grains. Chernykh also developed a large vineyard, introducing what has since become a major crop in the area. This region experiences warm (but not hot) and dry summers, with no average monthly temperatures above 71.6 °F (22.0 °C). According to

Occasionally also termed the "cool-summer Mediterranean climate", this subtype of the Mediterranean climate ( Csb ) is less common and experience warm (but not hot) and dry summers, with no average monthly temperatures above 22 °C (72 °F) during its warmest month and as usual an average in the coldest month between 18 and −3 °C (64 and 27 °F) or, in some applications, between 18 and 0 °C (64 and 32 °F). Also, at least four months must average above 10 °C (50 °F). Cool ocean currents, upwelling and higher latitudes are often

371-556: A mean temperature below 0 °C (32 °F) (or −3 °C [27 °F]), depending on the isotherm used). Regions in the Americas with this climate are influenced by the dry-summer trend (though briefly) that extends considerably poleward along the west coast, as well as the moderating influences of high altitude and relative proximity to the Pacific Ocean. These conditions maintain an unusually narrow temperature range through

424-455: A median income of $ 45,179 versus $ 43,021 for females. The per capita income for the CDP was $ 21,844. About 4.0% of families and 10.5% of the population were below the poverty line , including 8.1% of those under age 18 and 14.4% of those age 65 or over.

Under Trewartha 's modified Köppen climate classification, the two major requirements for a Cs climate are revised. Under Trewartha's system, at least eight months must have average temperatures of 10 °C (50 °F) or higher ( subtropical ), and

583-550: A season earlier than at the Dead Sea . In the Holy Land no rain at all falls in summer but early rains may come in autumn. The majority of the regions with Mediterranean climates have relatively mild winters and very warm summers. However, winter and summer temperatures can vary greatly between different regions with a Mediterranean climate. For instance, in the case of winters, Funchal experiences mild to warm temperatures in

There were 723 housing units at an average density of 457.8 per square mile (176.8/km ), of which 72.2% were owner-occupied and 27.8% were occupied by renters. The homeowner vacancy rate was 0.6%; the rental vacancy rate was 2.6%. 72.0% of the population lived in owner-occupied housing units and 27.2% lived in rental housing units. The median household income

742-424: Is closely associated with Mediterranean climate zones, as are unique freshwater communities, though vegetation native to the Mediterranean climate zone can also be found in the approximate nearby climate zones, which usually tend to be the humid subtropical , oceanic and/or semi-arid zones, depending on the region and location. Particularly distinctive of the climate are sclerophyll shrublands, called maquis in

The population was 1,707 at the 2010 census. Graton's ZIP code is 95444. The town also has a culinary reputation attributed to two restaurants in

848-576: Is famed for its high floral diversity , and includes such plant types as members of the Restionaceae , Ericas (Heaths) and Proteas . Representatives of the Proteaceae also grow in Australia, such as Banksias . The palette of California native plants is also renowned for its species and cultivar diversity. This subtype of the Mediterranean climate ( Csa ) is the most common form of

901-863: Is found throughout the warmer middle latitudes , affecting almost exclusively the western portions of continents in relative proximity to the coast. The climate type's name is in reference to the coastal regions of the Mediterranean Sea , which mostly share this type of climate, but it can also be found in the Atlantic portions of Iberia and Northwest Africa, the Pacific portions of the United States and Chile, extreme west areas of Argentina, around Cape Town in South Africa, parts of Southwest and South Australia , and parts of Central Asia . They tend to be found in proximity (both poleward and near

954-406: Is higher, steppe climates tend to prevail, but still follow the basic pattern of the Mediterranean climates. Irregularity of the rainfall, which can vary considerably from year to year, accentuates the droughts of the Mediterranean climate. Rain does not fall evenly, nor does the rain arrive at the same time or within the same intervals. In Gibraltar , for instance, rain starts falling nearly half

1007-414: Is noted as lying at the approximate furthest southern and eastern extent of Russian colonization of the Americas . Research on Fort Ross has indicated that several farms were developed inland from the coastal fur trading fort in northwestern Sonoma County. These farms or ranches were used for producing additional food and for agricultural projects conducted by Fort Ross's agronomist Yegor Chernykh. In 1836,

1060-658: The Köppen Climate Classification system, Graton has a warm-summer Mediterranean climate , abbreviated Csb on climate maps. At the 2010 census Graton had a population of 1,707. The population density was 1,080.9 inhabitants per square mile (417.3/km ). The racial makeup of Graton was 1,402 (82.1%) White, 10 (0.6%) African American, 29 (1.7%) Native American, 25 (1.5%) Asian, 3 (0.2%) Pacific Islander, 144 (8.4%) from other races, and 94 (5.5%) from two or more races. Hispanic or Latino of any race were 322 people (18.9%). The census reported that 99.2% of

1113-415: The subtropical ridge migrates towards the equator and leaves the area, making rainfall much more likely. As a result, areas with this climate receive almost all of their precipitation during their winter and spring seasons, and may go anywhere from four to six months during the summer and early fall without having any significant precipitation . In the lower latitudes, precipitation usually decreases in both

1166-604: The Andes in Northern Ecuador , Peru , Colombia , and Western Venezuela . The cold-summer subtype of the Mediterranean climate ( Csc ) is rare and predominantly found at scattered high-altitude locations along the west coasts of North and South America having a similar climate. This type is characterized by cool, dry summers, with less than four months with a mean temperature at or above 10 °C (50 °F), as well as with cool, wet winters, with no winter month having

1219-529: The CDP was 84.35% White, 0.50% African American, 1.49% Native American, 1.10% Asian, 0.06% Pacific Islander, 8.98% from other races, and 3.53% from two or more races. Hispanic or Latino of any race were 19.28%. Of the 690 households 30.9% had children under the age of 18 living with them, 49.1% were married couples living together, 10.0% had a female householder with no husband present, and 35.9% were non-families. 27.5% of households were one person and 8.8% were one person aged 65 or older. The average household size

Temperate climates or " C " zones average temperature above 0 °C (32 °F) (or −3 °C (27 °F)), but below 18 °C (64 °F), in their coolest months. The second letter indicates the precipitation pattern (" s " represents dry summers). Köppen has defined a dry summer month as

1325-782: The Mediterranean Basin, chaparral in California, matorral in Chile, fynbos in South Africa, and mallee and kwongan shrublands in Australia. Mediterranean vegetation shows a number of adaptations to drought , grazing , and frequent fire regimes. The small sclerophyllous leaves that characterize many of the perennial shrubs of this biome, help conserve water and prevent nutrient loss. The soils generally are of low fertility , and many plants have mutualistic relationships with nitrogen-fixing bacteria . Aquatic communities in Mediterranean climate regions are adapted to

1378-447: The Mediterranean climate typically experience hot, sometimes very hot and dry summers. Winters can be mild, cool or chilly, and some cities in this region receive somewhat regular snowfall (e.g. Kermanshah ), while others do not receive any (e.g. Casablanca ). Csa climates are mainly found around the Mediterranean Sea , southern Australia, southwestern South Africa , sections of Central Asia , northern sections of Iran and Iraq ,

1431-448: The Mediterranean climate, therefore it is also known as a "typical Mediterranean climate". As stated earlier, regions with this form of a Mediterranean climate experience average monthly temperatures in excess of 22.0 °C (71.6 °F) during its warmest month and an average in the coldest month between 18 and −3 °C (64 and 27 °F) or, in some applications, between 18 and 0 °C (64 and 32 °F). Regions with this form of

1484-605: The area. The town of Graton is roughly 20 miles (32 km) from the California coastline. Graton's agriculture was historically concentrated on apple farming, but like most of rural Sonoma County it now focuses on wine production. Graton has a total area of 1.58 sq mi (4.1 km ), all land. Graton is located at the southeastern end of Green Valley, on the east bank of the seasonally flooding Atascadero Creek . The elevation ranges from approximately 85 feet (26 m) above Mean Sea Level (MSL) at Atascadero Creek to 213 feet (65 m) MSL at Oak Grove School. Graton

1537-431: The average annual precipitation must not exceed 900 mm (35 in), as well as satisfying Köppen's precipitation requirements. [Chile] has four months of winter, no more, and in them, except when there is a quarter moon, when it rains one or two days, all the other days have such a beautiful sunshine that is not necessary to resort to fire. The summer is so temperate, with delicious airs, that man can go all day under

1590-400: The coast) of desert and semi-arid climates , and equatorward of oceanic climates . Mediterranean climate zones are typically located along the western coasts of landmasses, between roughly 30 and 45 degrees north or south of the equator . The main cause of Mediterranean, or dry summer, climate is the subtropical ridge , which extends towards the pole of the hemisphere in question during

1643-434: The cold current has a stabilizing effect on the surrounding air, further reducing the chances for rain, but often causing thick layers of marine fog that usually evaporates by mid-day. Similar to desert climates, in many Mediterranean climates there is a strong diurnal character to daily temperatures in the warm summer months due to strong solar heating during the day from sunlight and rapid cooling at night. In winter,

There is a "c" with 3 or less months' average temperature above 10 °C (50 °F), but this climate is rare and is very isolated. Under the Köppen classification, dry-summer climates ( Csa , Csb ) usually occur on

1749-557: 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

1802-706: 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

1855-432: 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,

There were 680 households, 193 (28.4%) had children under the age of 18 living in them, 304 (44.7%) were opposite-sex married couples living together, 90 (13.2%) had a female householder with no husband present, 19 (2.8%) had a male householder with no wife present. There were 35 (5.1%) unmarried opposite-sex partnerships , and 18 (2.6%) same-sex married couples or partnerships . 188 households (27.6%) were one person and 73 (10.7%) had someone living alone who

1961-530: 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

2014-592: 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

2120-505: 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

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

2226-546: 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

2279-564: 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

2332-537: 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 ,

2385-461: 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

2438-702: 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

2491-457: 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

2544-541: 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

2597-410: 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

2650-554: 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
