Like its people, Iran has one of the most diverse climates in the world, because of its placement over the equator and the different types of terrain across the country. There are only 13 different climates in the world, and Iran has 11 of them. Let’s pick a point on the map and work ourselves around this ancient land to learn more about its weather.

If anyone has been in Iran longer than a day they would know that when Iranians say north, they are talking about the provinces adjacent to the Caspian Sea. The Terrain and climate in these cities are like none other in the country. These cities are surrounded by the Alborz mountain range and they keep the humidity within that area, causing beautiful scenery, green mountains covered by rainforests, and of course, the great Caspian Sea which is the equivalent of a cherry on top of a sundae.

Iran Weather-North Of Iran

The North is rainy throughout most of the year, cold during the winter and hot and extremely humid during the summer with lesser rain. Speaking of summer and winter, Iran is a four-season country, meaning at any part of the country you get three months of spring, three months of summer, three months of autumn, and yes, you guessed it, three months of winter. Also, while we’re at it, because the Persian calendar was based on the rotation of the earth around the sun, the year starts at the very beginning of the season of Spring.

Iran Weather In The West and Northwest

Mountainous Northwest of Iran. Snowy mountains glowing with sunlight.

In provinces like West and East Azerbaijan and Ardabil, because of the mountainous terrain and the high altitude of the region, cities like Tabriz and Urmia, are cooler during the summer, with temperatures close to freezing and lots of snow during the winter. These cities have heavy rainfalls during the seasons of spring and fall, which could possibly also cause flooding in different parts. Nevertheless, visiting the northwest during spring and autumn especially places like the colorful mountains of Tabriz, Lake Urmia, the jungles of Arasbaran and many more would be nothing short of amazing.

The west of Iran is stretched over the Zagros mountains and is home to wonderful cities like Hamedan, Ilam, and Kermanshah. Some villages in this area are unbelievably integrated with the nature surrounding them. The weather in the west is very much like the northwest, extremely cold in the winters, and pleasantly cool in the summer. The history of this area dates back to thousands of years, meaning the weather and terrain here have always been welcoming to the people who passed through it.

The Coldest and Warmest Part of Iran?

On any given day in a year, there are specific parts of the country that have completely opposite climates. For instance, during the months of July and August, the heat in a city like Ahvaz, in Iran’s Khuzestan province is unbearably hot, and at the same time, there are cities like Sarein that still have snow-capped mountains and freezing cold nights. Sarein is in the Ardabil province in Northwestern Iran While Ahvaz is in the Southwest of the country. We will be exploring the South and Southwest in more detail next.
