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 bordering the Black Sea have a temperate Oceanic 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 2,200 millimetres (87 in) annually which is the highest precipitation in the country.
The coastal areas bordering the Sea of Marmara, 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.
Mountains close to the coast prevent Mediterranean influences from extending inland, giving the central Anatolian plateau of the interior of Turkey a continental climate with sharply contrasting seasons.
Winters on the eastern part of the plateau are especially severe. Temperatures of -30 to -40 °C (-22 to -40 °F) can occur in eastern Anatolia. Snow may remain at least 120 days of the year. In the west, winter temperatures average below 1 °C (34 °F). Summers are hot and dry, with temperatures often above 30 °C (86 °F) in the day. Annual precipitation averages about 400 millimetres (15 in), with actual amounts determined by elevation. The driest regions are the Konya plain and the Malatya plain, where annual rainfall frequently is less than 300 millimetres (12 in). May is generally the wettest month, whereas July and August are the driest
