Iran’s climate is predominantly arid to semi-arid, but the country’s vast size and varied geography mean conditions shift dramatically – from humid Caspian lowlands to scorching central deserts and snowy Alborz mountains. The live forecast above gives the most immediate picture for major cities.
What are Iran’s main climate regions?
Winter brings cold temperatures to the north-west and mountains, often with snowfall; summers are intensely hot across most of the country. The Caspian coast stays milder and far wetter, while the interior plateau sees dry skies and big temperature swings between day and night. For monthly and yearly averages, iran weather by month and iran weather yearly data help travellers plan.
How does the weather change through the year?
Spring (March–May) is generally pleasant, with moderate temperatures and occasional rain. Summer (June–August) is the hottest period, especially in the south and east. Autumn (September–November) cools down, and winter (December–February) brings cold conditions to Tehran, Tabriz and the north-west. For a forward look, check weather in iran 10 days or an iran weather forecast 30 days update. An iran weather map shows how fronts and pressure systems affect different regions. Iran weather rain is most common along the Caspian coast and in the north-west during winter and spring.
Does it snow in Iran?
Yes, snow is common in the Alborz and Zagros mountains during winter. Tehran often sees several snowy days each year, and ski resorts near the capital operate from December to April.
What is the best time to visit Iran?
Spring (March to May) and autumn (September to November) offer the most comfortable temperatures for travel, especially in central and southern parts. Summer can be extreme, particularly in desert areas.
How does Iran’s weather compare to Australia’s?
Iran’s inland deserts resemble Australia’s outback in summer heat and dryness, but its mountainous winters are far colder. The Caspian coast, by contrast, is much wetter than most of Australia.
