Geography              
The summer months in Istanbul are generally hot and quite humid. The winters can be cold and wet, although not as extreme as other areas of the country. June, July and August see temperatures creep up to 30 degrees, with very little rain. Spring and autumn are popular times to visit because of the comfortable climate, good for lots of walking and sightseeing, with highs between 15 - 25 degrees C, in April, May, September and October. By the winter, the dry cold air mass from the Black Sea and cold damp front from the Balkans brings a chilly season with daytime highs of between 10 - 15 degrees C, and nights much colder. Although rarely falling to freezing point, there is the occasional light snow in the city.

Tipping and Bargaining
