Tehran experiences a semi-arid climate with hot, dry summers and chilly, somewhat wetter winters. The live forecast above shows the current conditions, but for reliable planning it’s wise to check the weather in Tehran 10 days ahead, as conditions can shift quickly, especially during shoulder seasons.
When is the best time to visit Tehran?
The most comfortable months are spring (March to May) and autumn (September to November), when daytime highs range from 20–30°C. Summer (June–August) is intensely hot, often exceeding 38°C, while winter (December–February) brings cold nights and occasional snow. Pack layers if you visit in cooler months—a lightweight jacket is useful even in October.
What should you pack for a trip?
In summer, bring light, breathable fabrics, sun protection, and a reusable water bottle. Winter calls for a warm coat, hat and gloves, especially if you intend to explore the northern foothills. For the Tehran weather tomorrow, check the live forecast; rain is most likely between November and April. If you need a longer outlook, the Tehran weather 14 days forecast can help with itinerary planning.
Does Tehran get snow?
Yes, snow is common in winter, especially in the northern suburbs and the Alborz mountains. The city centre sees occasional light snowfall, usually in January and February, but it rarely stays on the ground long.
Is Tehran humid?
No, the climate is semi-arid, so humidity is low most of the year. Summers can feel very dry, which makes the heat more bearable, but also means you need to stay well hydrated.
How accurate are long-range forecasts for Tehran?
For planning, the Tehran weather 30 days forecast gives a general trend, but day-to-day reliability drops after 10 days. The Met Office and BBC provide the most trusted forecasts for up to 14 days.
