In winter: cold on the central plateau, hot on the Persian Gulf and in the region of Ahwaz and Susa.
In spring and autumn: very pleasant (between 18 ° and 25 °).
In summer: warm and dry (30 ° on average) and very hot on the Persian Gulf (45 ° and more).
Indeed, Iran has a wide variety of climates. Spring with blossoming trees and autumn with its multiple colors are the sweetest seasons. The summers are very hot, but dry. Snow is frequent in the high mountains in winter, but the coldest regions of the country are in the extreme north and west of the country.
The Iranian landscape is dominated by several mountain ranges. The Zagros and Alborz chains cover the western part. The eastern half consists essentially of a series of desert basins, such as the Dacht Kavir, dotted with rare salt lakes.
The climate diversity of the country is also visible from North to South: while the coastal plains of the Caspian Sea in the north of the country offer a subtropical climate, those of the Persian Gulf to the south have temperate winters and very hot and very hot summers Wet.
Periods from March to April to early June and from September to November are most suitable for travel.
