Iran’s weather varies sharply from the humid, semi-tropical Caspian coast to the arid interior and hot Persian Gulf shoreline. As the live forecast above shows, current conditions differ widely across the country, with Tehran experiencing a continental climate of warm summers and chilly winters, while southern cities like Bandar Abbas remain hot year-round.
What is Iran’s climate and geography like?
Iran sits at the crossroads of several climate zones. The Caspian Sea’s northern edge receives the country’s most precipitation, supporting lush forests. Inland, the Zagros and Alborz mountain ranges block moisture, creating vast deserts such as the Dasht-e Kavir and Dasht-e Lut, where summer highs regularly surpass 45°C. Coastal regions along the Persian Gulf and Gulf of Oman have a humid subtropical climate with mild winters and very hot, humid summers. Winter snow is common in the mountains and in Tehran, while the south rarely sees temperatures below 15°C.
What is the best time to visit Iran for weather?
The ideal travel window is spring (March to May) and autumn (September to November), when temperatures are mild across most of the plateau. Summers in the desert and south are extreme, while winter can be bitterly cold in the north and west. For travellers checking an iran weather map or looking up the weather in iran 10 days ahead, these shoulder seasons consistently offer the most comfortable conditions for a multi-city trip. An iran weather 14 days forecast is helpful for planning mountain treks or desert tours, as conditions can shift rapidly.
Does it ever snow in Iran?
Yes, snow is common in the Alborz and Zagros mountains from November through March. Tehran and Tabriz see several snowfalls each winter, while the southern coast and desert lowlands almost never receive snow.
How hot does it get in the Iranian desert?
Summer temperatures in the Dasht-e Lut can exceed 50°C in the shade. The region holds the official record for Earth’s hottest land surface temperature, reaching 70.7°C in 2005.
Is Iran humid year-round on the Caspian coast?
Yes, cities like Rasht and Anzali remain humid throughout the year. Annual rainfall exceeds 1,200 millimetres in places — far more than in Tehran or Isfahan — and fog is common in autumn and winter.
