  • High Season: March-May
  • Low Season: November-February
  • All Seasons: March-May (spring), June - August (summer), September - October (fall) November - February (winter)
  • The best time to visit Iran is between March and May, when the weather is ideal - not too hot, or too cold. This is the peak season for travelers across the country.
  • If you don’t mind slightly higher temperatures, you can also visit between June and October, when the weather is slightly warmer.
  • It would be good for you to keep track of festival times in Iran, as there are national holidays and stricter rules during festival times. Nowruz (around 20th March), and Ramadan (between May and June) can cause some disruptions in your travel plan.

Iran has a treasure chest of attractions - from the beautiful mansions at Qajar to the caravanserais of the ancient Silk Route, this is a country that is bountiful on your senses, and very easy on your wallet. Mostly, the best time to visit Iran is during the spring, between March and May, or at the end of the summer season, between September and October.

The weather in Iran during the spring is absolutely beautiful. It is really pleasant, with little to no rain. There will be temperature changes, depending on the regions - it will be slightly colder in the mountains than in the plains, but you can enjoy overall great temperatures across the country during these months.

While it gets quite hot during the summer months, if you visit between September and October, the weather is pretty good. The summer heat begins to wear off, and the winter chill hasn’t set in yet. Moreover, this is a shoulder period, so you will be able to enjoy the best of Iran without having to worry about the crowds. If you book in advance, you can also get better discounts on your accommodation and travel.


March to May — Spring / High Season

Tehran Skyline
Tehran, the capital city of Iran, has plenty of popular monuments such as the Azadi Tower, the National Museum, the Tehran Tower, and more.

Spring is the best time to visit Iran for a number of reasons. The weather slowly starts to get warmer after the winter. The nights might be slightly chilly, but the weather in Iran during the day is rather pleasant. This is the high season, so there will be a lot of crowds. You will have to book your travel and accommodation in advance, and the prices of travel might be higher.

  • Avg. Temperature: 43 – 82° F / 6 – 28° C (in Tehran)
  • Rainfall: 10 – 20 mm
  • Season: Spring
  • Highlights: Nowruz is one of the biggest Iranian festivals - and it happens around 21st March, for two weeks. The country will be really busy during this time, and some shops might be shut for celebrations, so plan your holidays accordingly. This is the perfect time to visit the Persian Gulf coast as the weather is beautiful. It is also a great time to visit places like Persepolis, Isfahan, or the Yazd province, where you will be able to sightsee, without having to struggle through the heat!

June to August— Summer / Low Season

Summer in Iran can get rather warm, so unless you can withstand a lot of heat, it is not a smart idea for you to travel to the country between June and August. There is little to no precipitation, and the desert areas get incredibly hot. It won’t be possible for you to do a lot of outdoor sightseeing, without facing the heat. However, this is a good time to visit the mountains. Moreover, you can enjoy high discounts, as this is a low season in Iran.

  • Avg. Temperature: 68 – 99° F / 20 – 37° C (in Tehran)
  • Rainfall: 10 – 10 mm
  • Season: Summer
  • Highlights: This is when to visit Iran if you want to head to the mountains. There won’t be a lot of snow, but the weather will be quite good. Shemshak and Dizin are great hilly destinations to visit during this period. You can also head to the coast, towards the Caspian sea, where the weather is much milder. The end of May and June is usually when the festival of Ramadan (Iran’s biggest festival, lasting the entire month) takes place. There might be restrictions on where you can travel, and what you can eat, drink, and wear during this month, so check up on the local customs before traveling.

September to October — Fall / Shoulder Season

Fall is when to visit Iran if you want to enjoy good weather, but without the crowds. There is still little rainfall, and the temperature begins to drop after the summer. Since the school holidays are over, there will be fewer crowds on the roads.

Avg. Temperature: 55 – 88° F / 13 – 31° C (in Tehran)
Rainfall: 10 – 10 mm
Season: Fall
Highlights: Fall is a great time to hit Iran’s popular tourist destinations without having to worry about crowds. Head to the blue mosque in Tabriz, or the beautiful gardens in Shiraz. Head to Tehran’s markets, or go trekking on the Sahand volcano. You will be able to get to these places on the low, and you won’t have to fight off a crowd to do the same!

November to February — Winter / Low Season

Winter is a low season, but there are some people who prefer traveling to Iran during the cold. The weather in Iran can get bitterly cold, especially in the mountains. The mountain passes might be closed due to excessive snowfall sometimes, so before you go skiing, it is suggested that you check the temperature to see if they are open. Snowfall is expected in Tehran as well.

  • Avg. Temperature: 32 – 61° F / 0 – 16° C (in Tehran)
  • Rainfall: 30 – 50 mm
  • Season: Winter
  • Highlights: There are a few exciting things you can do in winter. The wonderful Iranian festival of Yalda, or Shab-e Chelleh takes place around December 20th. Iranian households gather together to recite poetry and eat delicious fruits. This will be an immersive cultural experience like no other! If you are a fan of skiing, this is the best month for you to do so. Bam-e Tehran, Dizin, and Shemshak are the best skiing destinations.
