The south west of Turkey (Marmara, Aegean, and Mediterranean) has a characteristic Mediterranean climate, consisting of hot summers and mild winters. The hottest months are July and August with quite high humidity and temperatures around 30°C.Istanbul is fairly similar but can be much colder in the winter with some snow.

The Black Sea region (north) has a relatively temperate climate with warm summers and mild winters. There is also much more rain in this part of the country, and consequently the region has much more luscious vegetation.

With the inland regions usually being at a higher altitude than the coastal regions, there tends to be a notable difference in the climates. The extremes of Turkish weather occur in central and eastern Anatolia with very hot and dry summers with temperatures reaching 42°C, winters are freezing and snowy. Spring and autumn are the best times for travelling and sightseeing in these regions.

In the farther eastern and mountainous regions, the summers are milder and the winters harsher. Snow can lay on the ground for up to four months with temperatures as low as -35°C. These regions are ideal for winter sports.
