Typical weather
What Tehran is usually like
What a typical day looks like, hour by hour: 8am when you get up, 2pm in the afternoon, 8pm when you are out in the evening — on Iran’s own clock, at Tehran. Ten-year averages (2011–2020) measured at the capital, so this is Tehran, not the whole of Iran, and a mountain or a coast a few hours away can be nothing like it. Averages, not a forecast: a typical January rather than any particular one.

Twelve months in order. Tap any heading to sort by it — the driest month, the longest day, the afternoon closest to the one you like.
The colour is the month, not the weather: ✕ avoid.
Temperature and rainfall are ERA5. Generated using Copernicus Climate Change Service information 2026; neither the European Commission nor ECMWF is responsible for any use of this information.

Worth knowing
Five things that hold almost everywhere
- Grab (or the local equivalent) beats street taxis in most of Asia — and even where you don't use it, the app price tells you what's fair.
- ATMs: withdraw big and rarely, always in the local currency, and always decline the machine's kind offer to charge your card in pounds — that 'service' costs 3–6%.
- eSIM before you land (Airalo or similar) so you're online at arrivals; swap to a local SIM if you're staying weeks.
- Scooters anywhere: without the right licence category your travel insurance is void. That's the whole conversation.
- Save the local emergency number on day one, and know which private hospital expats use in your city — ask your host the day you arrive.
