Iran Weather

The seasons are clearly differentiated. Spring starts in March and is initially cold and windy, later becoming pleasantly warm and often sunny. Spring and autumn are easily the best times to come, and if you come in spring you avoid having countless Iranians tell you: 'Oh, but you must come back in the spring, it's beautiful.' Summer, which begins in June, is predominantly warm but hot at times, with plenty of sunshine interlaced with heavy rains. July is the hottest month, with temperatures ranging between 35 and 45°C (95-113°F). Autumn comes in September and is at first warm and usually sunny, turning cold, damp and foggy in November. Winter lasts from December until March and can include substantial snowfall, depending on how the weather is feeling and where you are. January and February can be bitterly cold, with temperatures often below -15°C (5°F) or -20°C (-4°F), though the days are often pleasantly mild, particularly in the south.
