The Climate of Iran is an extreme form of continental climate. The summers are hot and winters quite cold. The rainfall is very scant indeed over almost the whole of Iran except a narrow strip around the Caspian Sea where it is abundant.
Except for the coastal areas, most of the major cities of Iran are much removed from the Persian Gulf. They, therefore, have an extreme form of continental climate. In Tehran, for instance, it is usual for the mid day thermometer to exceed 104 F ( 40 C ) in July. Where as in January temperatures below 25 F (-4 C) are frequent. Spring and fall are comfortable. The average temperatures of April and October at Tehran are 60 F (16 C) and 65 F (18 C) respectively.
The total annual rainfall at Tehran is only 10 inches (250 mm) with months from May to September having almost zero rainfall. Nearly 90 percent of its rainfall comes from the western disturbance, an extra tropical depression, which is especially active in this area between December and March. The scanty rainfall accounts for its desert type of vegetation. In fact almost whole of Iran is arid and dry except the Elburz Mountains to the north which receive abundant rainfall to sustain vegetation.
In short Iran has a very dry and arid climate with extreme variations in temperature between the summer and winter months. The best season to visit this country is in spring and fall when the temperatures are moderate and pleasant.
