When to go
Iran has a variable climate. In summer, the weather can be cool as well as warm. Spring and fall are relatively mild, while summers are dry and hot. Very high temperatures can be experienced along the Persian Gulf and Oman Sea. A small area along the Caspian coast has a very different climate, here rainfall is heaviest from late summer to mid winter but falls throughout the year. In the northwest, winters are cold with heavy snowfall and subfreezing temperatures during December and January.
