The climate in Turkey has a vast diversity depending on the diverse topography and latitude.

Aegean and Mediterranean coastal areas enjoy the typical Mediterranean climate. There is hardly a drop of rain during the sunny and hot summer (May to October). Winters are rainy in these regions, and it very rarely snows, with the exception of mountainous areas higher than 2000 metres of these regions, which can be quite heavy.

The region around the Sea of Marmara, including Istanbul, also has some kind of Mediterranean climate, but it can rain, albeit a little, during summer (as showers which tend to last for 15-20 minutes) Its winters are colder than those of the western and southern coasts. Snow is usual, although it doesn’t stay on the ground for long and limited to only a few days every winter.

Black Sea region has a subtropical oceanic climate in the east (thanks to the protective shield effect of Caucasus mountains), and a colder oceanic climate in the west. In the eastern parts of this region, it heavily rains during all seasons. The temperature seldom drops below 5°C, so it seldom snows in the coast, though mountains are as snowy as it is expected to be, there are even glaciers around the year in the highest zones. Summers in the western parts of this region are hotter, and less rainy and snow is not an unusual event.

Most of the coastal areas have a high level of relative humidity during most of the year which makes hot weather feel hotter and cold weather feel colder than it actually is.

Interior areas generally have hot summers (though the nights are cool enough to make someone who is wearing only a thin t-shirt uncomfortable outdoors) and cold and snowy winters. The more easterly the location is, the colder the winters are and the heavier the snow is. The northeastern part (around Erzurum and Kars) is the only inland area which has cool and rainy summers.

The southeastern region near the Syrian border has a desert-like climate, temperature is constantly above 40°C during summers with no rain. Snowfall is occasional in winters.
