Iran’s capital, Tehran, with a population of around 9 million in the city and 16 million in the wider metropolitan area, is the largest city and urban area of Iran. The semi-arid climate of the city is largely defined by its geographic location, with the towering Alborz Mountains to its north and the central desert to the south. The weather is mild in spring and autumn, hot and dry in summer, and cold in winter. Because the city is large with significant differences in elevation among various districts, the weather is often cooler in the hilly north than in the flat southern part of Tehran.
