In most areas, Summers are warm and hot with virtually continuous sunshine, but high humidity on the Southern coastal areas of the Persian Gulf. Daily Temperatures can be very hot; on some days temperatures can reach easily 40°C or more, especially along the Persian Gulf and Oman Sea which causes a danger of heat exhaustion.
Temperature can be different across the country, you’ll find the weather more pleasant in Western and Northwestern cities of Iran such as Tabriz, Kurdistan, Ilam, Kermanshah and etc. And if you aren’t a psychrophilic, the best time to visit this cities, can be Summer.

The hottest days of Summer will be late July and early August, July 31th is Called “Chehelleye Tabestan” in Iran.

In my opinion Iran has the most pleasant weather in Autumn and if you are a rain lover, the best time to visit Iran is definitely Autumn.
It will be so lovely to walk in wet pavements covered with dried leaves with a cup of coffee while you’re sight seeing. Iran has a pleasant weather and everything looks so beautiful under the rain.
If you are interested in the exquisite culture of Iran and are wondering if there are any special festivals held in Autumn we have to answer YES! Qali Shuyan ceremony is one of the most famous festivals held in Kashan after the rose water festival.
It is a religious ceremony, held in the memory of Ali ibn Muhammad Baqer (Sultan Ali) on the third week of September.
The ceremony takes place in Mashhad Ardehal, a city 42 kilometers west out of Kashan.
The ceremony has a lot in common with a ceremony in Zoroastrianism and many people believe that it has changed after Islam like many other festivals and formalities. If you are a little interested in different religions and theater, it is strongly recommended to be in Kashan in the second week of Autumn. You’ll love it! But you should remember that Kashan’s weather isn’t as pleasant as it is in Spring. As Kashan is located in a deserted plateau, the weather can get so cold in Autumn so if you are going for Qai Shouyan ceremony, pack warm clothes.
The other popular festival is “Mehregan”, Iranians have celebrated it since 1000 BC. The festival is related to Zoroastrians and is held in the first day of Autumn in Zoroastrian cities of Iran. Mehregan starts on the first day of Autumn (September 22) and ends after 6 days, on 28th of September. People wear new clothes and set a colorful table. Everyone in the family stands in front of the mirror to pray at the beginning of the festival. They drink Juice as a good omen and participants wear eye linears from sormeh.
January is the coldest month and in some cities of Iran, weather gets freezing and the central and Southern lands are much warmer. The lowest temperature is 10 -12°C in cities near the Persian gulf and at the time people are buying their coffee in Northern cities of Iran, others are swimming in the warm water of Persian Gulf! February brings first signs of approaching spring. Temperatures are rising to about 13 °C except alpine regions where air is still cold.
There are plenty of amazing ski slopes in Iran and you can go skiing in the freezing weather of Iranian cities, and don’t forget that if culture is your favorite thing “Sadeh festival” and “Yalda celebration” are the two most famous Iranian cultural festivals which are held in different cities of Iran in the freezing weather.
