Because of Turkey's geographical conditions, one can not speak about a general overall climate. In Istanbul and around the sea of Marmara the climate is moderate ( winter 4 deg.C and summer 27 deg.C); in winter the temperature can drop below zero. In Western Anatolia there is a mild Mediterranean climate with average temperatures of 9 deg.C in winter and 29 deg.C in summer. On the southern coast of Anatolia the same climate can be found. The climate of the Anatolian plateau is a steppe climate (there is a great temperature difference between day and night). Rainfall is low and there is more snow. The average temperature is 23 deg.C in summer and -2deg.C in winter. The climate in the Black Sea area is wet, warm and humid (summer 23 deg.C, winter 7 deg.C). In Eastern Anatolia there is a long hard winter, where year after year snow lies on the ground from November until the end of April (the average temperature in winter is -13 deg.C and in summer 17 deg.C).
