Turkey has an overall temperate climate, but since it is located in a geographically diverse area, it contains several different climate regions. Coastal regions have milder weather throughout the year than the more arid interior, especially when compared to the Anatolian plateau.
Winters on the central plateau are severe, reaching temperatures as low as minus 40 degrees Fahrenheit in the eastern part of the region. Summers can reach highs of 86 degrees Fahrenheit. Despite the swings in temperature, the Anatolian region is still considered a temperate climate. It is specifically a continental climate, which is a climate characterized by warmer summers and cooler winters due to the land absorbing and reflecting large amounts of heat energy from the sun.
The Black Sea coastal region to the north is a complete contrast to the interior plateau. It is wet, humid and has lush greenery. It experiences an oceanic or maritime-temperate climate with mild summers and cool winters. The region is often cloudy or foggy and resembles Central Europe, but its averages are warmer.
The Mediterranean coast to the south is similar to the Black Sea coast. It is somewhat drier and warmer, but it does not experience the extremes seen in the truly arid Anatolian plateau.
The western region encompassing Istanbul and the coast around the Sea of Marmara is also rather mild. It is considered a transitional climate from the wet oceanic coastal climate to the more extreme continental interior.
The eastern-most regions of Turkey range from chilly in the mountains to very hot near the Syrian border. Both sections of this region are dry. The mountainous parts have summers that can reach 100 degrees Fahrenheit, but the area is often quite cold during the rest of the year. The Syrian border region is a mirror image of these contrasts. Its winters can reach 10 degrees Fahrenheit, but most of the time, it is very warm.
