By all accounts, Turley should have been experiencing a rather temperate climate. However, and despite the country’s position in an area where temperate conditions dominate, Turkey’s region experience significant climate variations. Because of the diversity of Turkey’s terrain and most importantly the imposing figures of its great mountain ranges that run parallel to the coasts, the country’s coastal regions milder climates, while weather in the inland Anatolia plateau is characterized by hot summers and cold winters with very little precipitation.
The climate experienced in the region that includes Istanbul and the area around the sea of Marmara (Marmara region) is typically moderate, its temperatures peaking at 27 C during the summer season, taking a nose dive just bellow zero during the winter. Unsurprising, the Agean region of Western Anatolia enjoys a mild Mediterranean climate with average temperatures of 9C in winter and 29C in summer, while Mediterranean region of the southern coast of Anatolia experiences almost identical conditions.
Moving towards the Central Anatolian region of the Anatolian Plateau Turkey weather takes a sharp turn veering towards a steppe kind of climate, characterized by marked difference in daytime and nighttime temperatures, low rainfall and considerably abundant snow. The average temperature is 23C in summer and -2C in winter.
The Black Sea region has a wet, warm and humid climate, with average summer temperatures around 23C and 7C for the winter season. In Eastern Anatolia and South-Eastern Anatolia winters are long and severe and thick layers of snow cover the terrain between November and April. Temperatures during winter drop to a freezing -13C reaching highs of 17C during summer.
If you are planning on visiting Turkey, your safest bet would be the spring and autumn season when Turkey weather is at its absolutely nicest, with abundant sunshine and generally clear skies, although occasional showers are always a possibility.
