The Marmara, Aegean and Mediterranean coasts of Turkey display a typical Mediterranean climate of hot summers and mild winters, though Istanbul can have some very cold snaps with snow in the winter. July and August are the hottest months with temperatures around 30°C with quite high humidity during the summer months.
Temperatures increase a few degrees when travelling to the south and water temperatures also become warmer. The swimming season is from June to September along the Marmara and north Aegean coasts, while it is from April to October on the south Aegean and Mediterranean coasts.

The Black Sea Region has a comparatively moderate climate; the summers are warm and winters are mild. Rainfall is also heavier here than in any other region. The swimming season is from June to early September though the weather is not so dependable.


There is quite a difference between the climate of the coastal and the inland regions which tend to be at higher altitudes. The Turkish weather reaches its extremes in central and eastern Anatolia and the Eastern parts of the country, with hot, dry summers when the temperatures may reach 42°C, and freezing, snowy winters. Thus spring and autumn are best for sightseeing and travelling in this part of the country.


In the mountainous and Eastern regions of Turkey, the summers become milder and the winters harsher – temperatures can drop as low as -30°C to -38°C and snow may lay on the ground for around four months, making them ideal for winter sports.
