Rain season
Tehran averages 230mm annually, with most rain falling November–April as frontal systems cross from the Mediterranean and Caspian regions. The Alborz Mountains to the north trap cold air in winter and produce snow at the city's 1,200m elevation. Summers (June–September) are long, hot, and essentially rainless.
