The province’s southern areas are under the influence of the Mediterranean climate, so that the summers are generally hot and dry, while winters are warm and wet. The Amanos Mountain range between Gaziantep and the Mediterranean gives the province’s interior a more or less continental type of climate. Prevailing winds in Gaziantep are the poyraz (northeast) in winter and the karayel (northwest) in summer. The climate is harsher still in the high parts of the Gaziantep Plateau and the Sof Mountains.
