Get to know Tehran
A sense of the place
Tehran is the capital and largest city of Iran. It is also the capital of Tehran province and the administrative center for Tehran County and its Central District. With a population of around 9 million in the city, and 16.8 million in the metropolitan area, Tehran is the most populous city in Iran and West Asia, the largest metropolitan area in the Middle East and the 24th-most-populous metropolitan area in the world. Greater Tehran includes several municipalities, including Eslamshahr, Shahriar, Qods, Malard, Golestan, Varamin, Pakdasht, Qarchak, Nasimshahr, Parand, Pardis, Andisheh, Fardis, Tajrish, and Rey. In classical antiquity, part of the territory of present-day Tehran was occupied by Rhages, a prominent Iranian city that was not destroyed in the medieval Arab and Mongol invasions. Rey is absorbed into the metropolitan area of Greater Tehran.
Weather through the year
When to visit Tehran
Rain and outdoor plans
November averages about 45 mm of rain, compared with 6 mm in June. Rainfall alone does not identify a single best month; compare temperatures with the activities you plan.
Planning time outdoors
April, October combine monthly mean temperatures of 12–22°C with less than 100 mm of precipitation. These are useful dates to compare for a walking-focused visit; check daylight, opening times and the forecast for your actual trip.
Monthly mean temperatures reach at least 25°C in June, July, August. For sightseeing, plan shade, water breaks and accommodation cooling into your day; daytime temperatures can be higher than these day-and-night averages.
January, December have monthly means below 5°C. For a stay then, compare accommodation heating and keep indoor options in your itinerary. These figures do not establish snow cover or ski conditions.
