Except for the slopes to the Caspian Sea in  Alborz mountains rang,as well as the western slopes of the Zagros Mountains, which have relatively significant rainfall,the rest of the country is more or less deprived of this natural benefit and is often considered the driest region.

In general, Iran's climate is affected by Western or Mediterranean borders.

Except for wet and semi-humid areas, which are the northern slopes of the Alborz and the western slopes of the Zagros, the weather in most parts of the country goes by the end of the spring, and the dry and warm season begins in the inner regions. This season will sometimes continue until the middle of the fall season. From then on, the Alborz and Zagros heights and other significant peaks of the country, slowly begin covering by the snow, followed by the winter fall, which is mostly snowy. Thus, most of the country's lands beside the plain of Khuzestan and the coastal strip of the Persian Gulf and Oman Sea sink into the snow and frost.
