Spring (March to May) and autumn (September to November) are widely regarded as the best times to visit Tehran. During these months, the weather is generally mild and pleasant, making it ideal for exploring the city's outdoor attractions such as the Golestan Palace, Tehran Grand Bazaar, and the city's numerous parks like Park-e Shahr or Park-e Jamshidieh. Spring brings the Iranian New Year, known as Nowruz, which is celebrated around March 21st, marked by public holidays and a festive atmosphere. This makes it a particularly vibrant time to experience Persian culture and traditions. Moreover, the city is less crowded than during the hot summer months, and accommodation prices can be more reasonable before the peak tourist season.
Summer (June to August) in Tehran is hot, with temperatures sometimes exceeding 40°C (104°F), which might not be comfortable for everyone. However, the evenings are cooler, and there are numerous cultural events and festivals to enjoy. If you're planning on venturing into the nearby Alborz mountains for trekking, this season offers clear skies and great conditions for hiking. Conversely, winter (December to February) brings cold temperatures and occasional snowfall, which can be beautiful, but also chillier for city exploration. Travelers seeking a winter experience can head to ski resorts like Dizin or Shemshak, situated north of Tehran. It should be noted that air pollution can be quite high during the winter, which might affect travel plans for those with respiratory issues.
