Turkey (Turkish: Türkiye), officially the Republic of Turkey, is a transcontinental country, located mostly on Anatolia in Western Asia and on East Thrace in Southeastern Europe. Turkey is bordered by eight countries: Bulgaria to the northwest; Greece to the west; Georgia to the northeast; Armenia, Iran and the Azerbaijani exclave of Nakhchivan to the east; and Iraq and Syria to the southeast. The Mediterranean Sea is to the south; the Aegean Sea is to the west; and the Black Sea is to the north. The Sea of Marmara, the Bosphorus and the Dardanelles (which together form the Turkish Straits) demarcate the boundary between Thrace and Anatolia; they also separate Europe and Asia. Turkey’s location at the crossroads of Europe and Asia makes it a country of significant geostrategic importance.

The coastal areas of Turkey bordering the Aegean Sea and the Mediterranean Sea have a temperate Mediterranean climate, with hot, dry summers and mild to cool, wet winters. The coastal areas of Turkey bordering the Black Sea have a temperateOceanic climate with warm, wet summers and cool to cold, wet winters. The Turkish Black Sea coast receives the greatest amount of precipitation and is the only region of Turkey that receives high precipitation throughout the year. The eastern part of that coast averages 2,500 millimetres annually which is the highest precipitation in the country.

The coastal areas of Turkey bordering the Sea of Marmara (including Istanbul), which connects the Aegean Sea and the Black Sea, have a transitional climate between a temperate Mediterranean climate and a temperate Oceanic climate with warm to hot, moderately dry summers and cool to cold, wet winters. Snow does occur on the coastal areas of the Sea of Marmara and the Black Sea almost every winter, but it usually lies no more than a few days. Snow on the other hand is rare in the coastal areas of the Aegean Sea and very rare in the coastal areas of the Mediterranean Sea.

Conditions can be much harsher in the more arid interior. Mountains close to the coast prevent Mediterranean influences from extending inland, giving the central Anatolian plateau of the interior of Turkey acontinental climate with sharply contrasting seasons.
