climate of turkey
Turkey's climate is varied and generally temperate, with the regions bordering the Mediterranean and Black Sea heavily affected by the coasts, and the interior being drier and more continental.  
Coastal areas in the southern half of the country, including Antalya, İzmir, Adana, feature a very typical Mediterranean climate, with hot, dry summers and mild, rainy winters. Coastal areas in the north are cooler and have more oceanic influence; cities around the Sea of Marmara, including İstanbul, Bursa, İzmit, have cool, frequently rainy and occasionally snowy winters, and warm to hot, moderately dry summers. Further east, near the Black Sea coast, the dry season completely disappears, leading to cool, rainy and occasionally snowy winters, and warm, showery summers. 
The lower plateaus of the interior is generally continental, and mostly feature hot, dry summers, and cold, snowy winters. Despite this, winter precipitation varies widely, leading to humid rainfall regimes near areas like Bitlis, while rain-shadowed areas are semi-arid. 
Higher plateaus that nevertheless allow permanent settlement, like Kars and Ardahan, are high-continental and sometimes subalpine, with frigid, snowy winters, and mild, rainy summers. 
Dry summers in the south and west, along with moderate aridity in the interior makes the country vulnerable to climate change.

Regions
Mediterranean climates
"True" Mediterranean climate
A "true", or rather eu-Mediterranean (Köppen: Csa, Trewartha: Cs) climate exists on sea level from the coasts of Antakya to around Muğla, and north to around Manisa, which is generally considered to be its northern limit. Average temperatures range between 17–20 °C (63–68 °F); winters have means around 7–10 °C (45–50 °F), while summers have mean temperatures between 26–29 °C (79–84 °F). Precipitation amounts to around 600–1,200 millimetres (24–47 in), all of it rain. Summers get almost no rain, while winters receive plentiful, and sometimes copious amounts of it. Winter precipitation depends on local topography, with enclosed bays of convergent air, such as Antalya, getting almost twice the amount of rain as storm-protected areas such as Mersin. 

Mountains around the region still show the Mediterranean rainfall pattern, but have mild summers and below-freezing temperatures during winter, creating a zone which may be termed oro-Mediterranean.

Pre-Mediterranean climate
A pre-Mediterranean climate (Turkish: Akdeniz sâhil ardı iklimi, Köppen: Csa, Trewartha: Cs/Do/Dc) exists in relatively continental areas influenced by the Mediterranean climatic system, notably around the inner Aegean and Southeastern Anatolia. Average temperatures range between 14–18 °C (57–64 °F) with winter means around 1–6 °C (34–43 °F), and summers as hot as (or hotter than) the Mediterranean. Rainfall follows the general pattern of the Mediterranean region, but sunshine is sometimes noticeably lower, and precipitation amounts are lower than the Mediterranean region, between 400–800 millimetres (16–31 in). Snow can also fall in this area, unlike the coastal Mediterranean region.

Transitional zone
Marmara dry-summer temperate climate
The climate around the Marmara Sea (Turkish: Marmara geçiş iklimi, lit. 'Marmara transitional climate', Köppen: Csa/Csb/Cfa/Cfb, Trewartha: Cs/Cf/Do) is complex, transitional and often microclimatic. It wraps around the sea, covering Bursa, Bilecik, southern İzmit and İstanbul, as well as Tekirdağ. Often of a meso- or supra-Mediterranean quality at sea-level; its vegetation at sea level is similar to the lower mountains of the "true" Mediterranean region, with heat-tolerant broadleaf oaks and occasional mesophilous trees, such as beech. Therefore, it is generally considered mild-temperate and not subtropical in Turkish sources and furthermore, Bohn, in a survey of European vegetation and climate, calls the climate sub-continental sub-Mediterranean.Its average temperatures range around 12–15 °C (54–59 °F) at sea level. Its summers are generally cool for the Mediterranean, but warm for oceanic climates, with means around 20–25 °C (68–77 °F), varying on a microclimatic level. Winter means range between 2–6 °C (36–43 °F), with a noticeable decrease further inland. Precipitation amounts to 600–1,100 millimetres (24–43 in). Winters are very cloudy, with the amount of rainy days far surpassing much of Europe; while snow falls occasionally, often with sea-effect. Summers are moderately dry, but feature occasional thunderstorms, sometimes severe; along with the Black Sea climatic region further east, areas around the Marmara Sea have their peak thunderstorm activity in early and late summer.
Mountains here often quickly transition into subalpine climates, most notably Uludağ.

Thracian sub-humid climate
Inland regions northwest of the Marmara Sea have a transitional, sub-humid climate (Köppen: Csa/Cfa, Trewartha: Cs/Cf/Do), with average temperatures matching those of the Marmara Sea, albeit with colder, snowier winters and hotter summers. The vegetation here is pre-steppic, mostly oak savanna.
This area does have similarities to the pre-Mediterranean climate further south, but its lower sunshine, light winter precipitation and milder, wetter summers distinguish the two. The area's thunderstorm season peaks in May and early June, resulting in a slightly earlier season than that of the Marmara Sea.

Humid maritime climates
Western Pontic climate
A mild, humid temperate climate (Köppen: Cfa/Cfb, Trewartha: Cf/Do) exists from the northern coast of Istanbul to İnebolu, at sea level around the coast of the Black Sea. Its vegetation is deciduous broadleaf, and resembles the supra-Mediterranean zone at sea level, although it is part of a different floristic zone, specifically the Euxinic one.
Its average temperatures range around 12–14 °C (54–57 °F) at sea level, with summer means around 20–23 °C (68–73 °F) and winter means around 4–6 °C (39–43 °F). Rainfall is well-distributed and quite frequent, generally around 900–1,500 millimetres (35–59 in) with a spring drying pattern, instead of a summer-dry one. Winter snowfall is about the same amount as the Marmara region, but winter means are raised by Foehn winds.

Central Pontic climate
In sheltered locations around Sinop and Samsun, the climate (Köppen: Cfa, Trewartha: Cf) is noticeably drier and warmer than the Western Pontic zone, but somewhat cooler, and much drier than the Eastern Pontic zone. Meso-Mediterranean vegetation resurfaces here, and coexists with broadleaf forest.  Average temperatures range around 13–15 °C (55–59 °F), with summer means around 22–25 °C (72–77 °F) and winter means around 6–8 °C (43–46 °F). Rainfall follows the general distribution of the region, but the area is less humid than expected in all seasons.

Eastern Pontic climate
As the Black Sea coast assumes a southwest-northeast direction once again, rainfall increases, and forms the near-subtropical, extremely humid climate (Köppen: Cfa, Trewartha: Cf) prevalent in the eastern Black Sea region. Featuring temperate rainforests, its temperatures are very slightly warmer than the transitional zone further west, but rainfall in this region is nearly constant in frequency, varying only by intensity. Rainfall amounts are also quite copious at 1,500–2,500 millimetres (59–98 in), with a spring drying pattern. Some parts of the region get below 1,200 hours of sunshine, values far below Western Europe and more comparable to subpolar regions.
Mountains in this region have a perhumid, alpine climate with verdant meadows (Turkish: yayla) alternating with krummholz and boreal forests.

Continental climates
Pre-Pontic sub-humid continental climate
Between the humid Pontic climate and semi-arid conditions further inland, a sub-humid to humid continental climate (Turkish: Karadeniz sâhil ardı iklimi, lit. 'Pre-Pontic climate', Köppen: Dfb, Trewartha: Dc) exists, most notably near Kastamonu. Average temperatures range around 8–11 °C (46–52 °F), with means of 18–21 °C (64–70 °F) during the hottest month and winter means just below the freezing mark. Rainfall is around 500 millimetres (20 in), with a spring storm season.

Northeastern high-continental climate
In the far-northeast of the country, often in elevations above 1,500 metres (4,900 ft), the summerly drying trend is no longer observed, and a unique, high-continental climate (Köppen: Dfb/Dfc, Trewartha: Dc/Ec) forms near Kars and Ardahan. Here, average temperatures are generally just above the freezing mark, while summers average around 15 °C (59 °F). Winters are the most severe in the country, with lows routinely below −18 °C (0 °F). Rainfall is generally around 500–700 millimetres (20–28 in) with an early-summer wet season.

Orographic rain-belt continental climate
On the foothills of the Anti-Taurus and Zagros Mountains, south of the Armenian highlands and, in general, near the continental foothills of the southern Alpide belt in Turkey, an orographically-induced rainbelt forms a Mediterranean-influenced continental climate (Köppen: Dsa/Dsb, Trewartha: Dc), high in precipitation. Temperatures average around 8–12 °C (46–54 °F) with winter means around −3 °C (27 °F) and summer temperatures averaging between 21–25 °C (70–77 °F). Precipitation is heaviest in early-spring, with totals above 800 millimetres (31 in). Winters are very snowy. Despite this high precipitation, summer aridity keep the vegetation of the area pre-steppic.

Semi-arid continental climate
In drier areas of Central and Eastern Anatolia, a semi-arid, occasionally sub-humid climate (Köppen: BSk/Dsa, Trewartha: BS/Dc) takes hold, due to extensive rain-shadowing from all sides. Here, summer means range around 22–25 °C (72–77 °F), while winter means are around freezing, averaging out to around 10–13 °C (50–55 °F). Precipitation is scarce at around 300–400 millimetres (12–16 in), and heaviest in late-spring.
