Tehran Weather in July

July heat in Tehran

July is Tehran's hottest month, tied with August for the highest daytime temperature. Highs reach 38°C, and afternoons feel dry, glaring and hard on your energy. Rain is rare, so don't count on a shower to cool things down. June is slightly less hot, while April, May and October are much more comfortable for walking around.

The cooler evenings suit dinner in Darband, where cafés and restaurants line the foothill streets. Keep indoor sights, such as the National Museum of Iran, for the hottest part of the day. A long walk through central Tehran can feel punishing by afternoon.

Events and crowds

There's no dependable, fixed citywide festival to plan around in July. Iranian public holidays follow the lunar calendar, so religious dates shift between years. Check the calendar for your travel year before building a trip around one.

If you hate crowds, July may feel easier than spring or autumn at major sights, though Tehran doesn't empty out completely. Some families travel during school holidays, while the heat puts many visitors off. Tourist demand is generally lower than in the best months, April to May and October, so you may find accommodation less pressured.

July in Tehran: local tips

Save outdoor stops for evening, and use the Metro between far-apart sights. For a break from the city centre, take the route towards Tochal; the mountain air can feel cooler, though the cable car and trails are still exposed.

At the Grand Bazaar, go early rather than wandering its covered lanes in the afternoon crush. It's easier to browse the shops and stop for a plate of tahdig, crisp rice served with a meal, before the heat builds. Travelling with kids? Keep the middle of the day for a museum or a quiet rest.
