The best time to visit Tehran is typically during spring (March to May) and autumn (September to November) when weather conditions are mild and comfortable for sightseeing. Summers in Tehran can be hot, with temperatures rising significantly, while winters are cold, especially near the Alborz foothills. Visiting in spring also offers blooming parks and active cultural events throughout the city. Autumn brings colourful landscapes and is ideal for exploring museums and historic sites without intense heat. Seasonal festivals and celebrations like Nowruz (Persian New Year) in March add cultural richness to visits. Holiday periods can be busier and more expensive, so planning ahead is recommended. Because air pollution can vary seasonally, it’s good to check local air quality forecasts when planning outdoor activities.
