Introduction

---

In Turkey, there is a noticeable variety of climates, with considerable differences between the areas, and also with some microclimates due to the different exposure of slopes and coasts.
The coastal areas have generally a mild climate, but the coast of the Black Sea is colder than that of the Mediterranean. The interior has a continental climate, with cold, snowy winters and hot, dry summers, though nights remain usually cool.
Summer is dry and sunny throughout the country, except on the north-east coast. In all the inland and south-central regions, the driest months are July, August and September.
The map below shows the climate zones of Turkey.

1- Eastern Thrace

---

Edirne

In this area of Turkey, south-east of Bulgaria, where the city of Edirne (the ancient Adrianople) is located, the climate is slightly continental: winters are quite cold, with a January average around 3.5 °C (38 °F), and summers are hot, though tempered by the breeze. Here, cold spells with snow and frost may occur in winter as well as heat waves in summer.
Here are the average temperatures in Edirne.

Precipitation in Edirne is not abundant, and there is a relative minimum in summer, when, however, brief thunderstorms may occur. Here is the average precipitation.

The sun in Edirne is seen quite rarely in winter, while in summer the sky is normally clear. Here are the average sunshine hours per day.

2- Istanbul and northern coast

---

In the area of Istanbul and Bursa, in the small portion of European Turkey and in the area beyond the Sea of Marmara and the Straits of Bosphorus and Dardanelles, the climate can be described as transitional Mediterranean, with relatively cold winters and hot and quite sultry summers.

Istanbul

In Istanbul, the average temperature in January is around 6.5 °C (43.5 °F), but sometimes cold air masses from the Balkan Peninsula or Russia reach this area, bringing some cold and rainy days, and even snow (in Istanbul, there are about 15 days per year with snow, mostly from December to March). Summer, when the average temperatures are around 25.5 °C (78 °F) in July and August, is the least rainy season, and August is the driest month, while autumn and winter are the rainiest seasons. Here are the average temperatures.

The sun in Istanbul is rarely seen in winter, partly because fog can sometimes form, while in summer, the sky is often cloudless.

The sea in Istanbul, very cold in winter, becomes warm enough for swimming in July and August, as we can see in the following table.

In the southern part of this climatic zone, the ruins of ancient Troy are found.
Along the coast to the east of Istanbul, winter is slightly milder, while summer becomes progressively rainier as you move to the east.

Trabzon

For example, in Trabzon, the monthly average temperature ranges from 7.5 °C (45.5 °F) in February to 25 °C (77 °F) in August. Here are the average temperatures.

In Trabzon, 885 millimeters (34.8 inches) of rain fall per year, with a minimum in summer. Here is the average precipitation.

In Trabzon, the sun does not shine very often, as can be seen in the following table.

In Trabzon, the sea is slightly warmer than in Istanbul and is warm enough for swimming from July to September.

3- North-east Coast

---

In the easternmost part of the Turkish coast of the Black Sea, east of Trabzon, from Rize to the border with Georgia, the climate can be defined as almost oceanic: the average temperature is similar to that of Trabzon, but the rains are abundant in all seasons, so that even more than 2,000 mm (80 in) of rain fall per year. However, the summer rains are not continuous, but they are concentrated in periods of bad weather which last a few days.

Rize

Here is the average precipitation in Rize.

In Rize, winter is milder than in the area of Istanbul, with less frequent snowfalls. Here are the average temperatures.

In Rize, the sun does not shine very often, even in July and August, when there are only 5/5.5 hours of sunshine a day.

4- West Coast

---

Along the west coast of Turkey, overlooking the Aegean Sea, where the remains of ancient Greek cities like Pergamum and Ephesus are found, the climate is Mediterranean, with mild, relatively rainy winters and hot and sunny summers. The summer is tempered by the breeze along the coasts and the islands of the Aegean Sea, though at times the breeze is replaced by a strong and persistent wind from the north, called Meltem.

Izmir

In Izmir (or Smyrna), winter is mild, with an average in January around 8 °C (46.5 °F); cold waves may still occur, but they are shorter and rarer than in the area of Istanbul. There are on average only 3 days with snowfall per year.
Summer is sunny and hot. High-temperature records are around 43 °C (109.5 °F). Here are the average temperatures.

The sun in Izmir shines regularly in summer, while in winter there is an alternation between cloudy and sunny days.

Owing to the north wind that prevents the sea from warming in summer by mixing the water layers, the sea near Izmir is never very warm.

The amount of rainfall on the west coast goes between 700 and 1,000 millimeters (27 and 40 inches) per year, with a maximum in winter and a minimum in summer, when it almost never rains.

5- South Coast

---

Along the southern coast of Turkey, and in the short stretch of coast north of Syria, the climate is still Mediterranean, though warmer than on the west coast, and even more so than on the Black Sea coast. Winters are quite mild, with average highs around 15 °C (59 °F), while in summer, the maximum temperatures are definitely hot, ranging between 30 and 35 °C (86 and 95 °F). Rainfall is concentrated from mid-October to mid-April, when it can be abundant, and can sometimes be torrential, particularly on the slopes facing west and southwest.

Antalya

In Antalya, about 1,050 mm (41.5 in) of rain fall per year, but it almost never rains from June to Spetember, while the rains are abundant in winter. Here is the average precipitation.

In Antalya, the monthly average temperature ranges from 10.5 °C (51 °F) in January to as high as 29 °C (84 °F) in July and August.

In Antalya, the sun shines quite often even in winter, except in periods of bad weather, while in summer the sky is normally clear.

Near Antalya the sea is warmer than in the north and west coast, and it's warm enough for swimming from June to October.

6- Anatolian Plateau

---

In the vast inland plateau, the climate is continental, with significant variations both between night and day and between winter and summer. Precipitation is scarce, around 300/500 mm (12/20 in) per year, with a maximum in winter and minimum in summer, which is normally sunny. In this area, the climate is fairly uniform, and varies mainly with altitude, however, it becomes progressively more continental when going towards the east.

Ankara

The capital of Turkey, Ankara, is located in the center of the plateau, about 900 meters (3,000 feet) above sea level. Here, winter is cold and snowy, with a January average of 0.5 °C (33 °F), but the temperature can go down to -20 °C (-4 °F) during cold air outbreaks from Russia. Summer is hot and dry, sometimes scorching during the day, when temperatures can reach 38/40 °C (100/104 °F) in the worst moments, while nights remain generally cool. Here are the average temperatures.

In Ankara, annual precipitation is around 400 mm (15.5 in), so it's not abundant. Here is the average precipitation.

The sun in Ankara is rarely seen in winter, while in summer it shines regularly.

In this area, at about 1,100 meters (3,600 feet) above sea level, we find the region of Cappadocia, where lies the city of Goreme, famous for the "fairy chimneys" or "earth pyramids". Here, the climate is similar to that of Ankara: the average January temperature is just below freezing (0 °C or 32 °F), and snow is quite frequent (the landscape of this region takes on an even more magical appearance under the snow), while the average in July and August is around 22 °C (72 °F), with highs around 29 °C (84 °F), but with possible scorching days.

7- Eastern Plateau

---

In the easternmost provinces, near the border with Georgia, Armenia and Iran, the climate is really harsh, not only because of the higher altitude, which generally ranges between 1,200 and 1,600 meters (3,900 and 5,200 feet), but also because of the proximity to Russia, from which cold air masses can arrive; in fact, during winter this is one of the coldest areas not only of Turkey, but of the entire Europe. Lake Van, at 1,600 meters (5,250 feet) above sea level, is large enough to temper a little the climate, especially in winter, when the average temperature along its banks is around -4/-2 °C (25/28 °F), but further to the north, in the provinces of Erzurum and Kars, the January average drops to nearly -10 °C (14 °F) at 1,500 meters (5,000 feet).

Van

These are the average temperatures of Van, located near the lake of the same name.

The rainfall pattern in the eastern part of the plateau is similar to that of the central-western part: precipitation is not abundant, there are snowfalls in winter, while summers are dry. Here is the average precipitation in Van.

In Van, as often happens in Turkey, the sun shines regularly in summer, while in winter there is an alternation between cloudy and sunny days.

Erzurum

In Erzurum, a city of 360,000 inhabitants in the north-east of Turkey, 1,700 meters (5,600 ft) above sea level, the average temperature in January is -10.5 °C (13 °F), so it's colder than in a northern Europe city like Helsinki. The absolute cold record is -37 °C (-34.5 °F), and that of April is still -22 °C (-7.5 °F). Summer is quite warm during the day, but nights remain cool, and sometimes even cold. There are, however, also hot days. The highest record is 38 °C (100.4 °F).
Precipitation is not abundant, only 400 mm (15.7 in) per year, with two minima in summer and winter and a maximum in spring. During winter, however, snowfall occurs quite often, and it can sometimes be abundant.
Here are the average temperatures.

8- High Mountains

---

In Turkey, there are several mountainous areas, where the altitude exceeds 2,000 meters (6,500 feet). For instance, in the northwest, near Bursa, in the Olympus of Mysia (Uludag), you will find the most famous winter sports resorts of the country. In addition, there are much higher mountains in the north-east (Pontus), in the south-west (Taurus), and in the eastern region, where we find Mount Ararat, which stands out with its 5,165 meters (16,945 feet). In the map above, we colored the mountainous areas in brown. Here, the climate is Alpine, and of course the temperature decreases with altitude. At higher altitudes, for instance on Mount Ararat, glaciers are found.

9- Southern semi-desert areas

---

In the south-eastern provinces, near the border with Syria and Iraq, from Diyarbakir and Batman towards the south, the altitude ranges between 400 and 700 meters (1,300 and 2,300 feet). Here, the winter is quite cold, averaging a few degrees above freezing, but with possible snowfalls and frosts, which are more frequent in the northern part, but the main feature of this area is the hot summer, when temperatures can exceed 45 °C (113 °F).

Diyarbakir

In Diyarbakir, 680 meters (2,200 feet) above sea level, the average temperature ranges from 2 °C (35.5 °F) in January to 30 °C (86 °F) in July, when highs are around 38 °C (100 °F). The lowest recorded temperature is -23 °C (-9.5 °F), while the highest is no less than 46 °C (115 °F).

Here too, precipitation is not abundant and is concentrated in the cold half of the year, while in summer, it rains very rarely. Here is the average precipitation.

In the south-east of Turkey too, the sun shines regularly in summer, while in winter, there is an alternation between cloudy days and sunny days.

Cizre

Further south, in Cizre, at 400 meters (1,300 feet), near the border with Syria, the average maximum in July is as high as 41 °C (106 °F), while the daily average in January is 6.5 °C (43.5 °F), so winter is usually quite mild. Here are the average temperatures.

Given its proximity to the mountains, the rains in Cizre are a bit more abundant, around 730 millimeters (29 inches) per year, but here too, in summer it rains very rarely.
