Iran has a very varied climate. In general, the best travel time for Iran can be divided in two periods; spring and autumn. These are the months March to May and September to November.

However please be aware that the Persian New Year (Eid Nowruz) takes place the end of March and the major cities will be full of Iranian tourists. In mid-April the crowds will disappear again.Between June and October (summer), temperatures in Iran can be very high, but it is still bearable. However very high temperatures can be experienced along the Persian Gulf and Oman Sea. In June, September and October, Iran faces the perfect weather to move into the mountains due to its warm days and relatively cool evenings.
Between November and February it can get extremely cold in Iran. In the northwest you can expect heavy snowfall and freezing temperatures during December and January. Roads can be closed for longer periods in this time.
A small area along the Caspian coast has a very different climate, here rainfall is heaviest from late summer to mid winter but rain falls throughout the year.
