Climate in Tehran, Iran

According to andyeducation, Tehran, the capital and largest city of Iran, is situated in the northern part of the country, nestled against the Alborz Mountains. The city’s climate is classified as a semi-arid continental climate with distinct seasons and notable temperature variations. In this comprehensive description, we will explore the various facets of Tehran’s climate, including temperature, precipitation, seasons, and notable climate-related characteristics.


Tehran experiences a wide range of temperatures throughout the year, with clear variations between seasons. These temperature fluctuations are influenced by the city’s elevation and proximity to the Alborz Mountains.

  • Summer (June to August): Summers in Tehran are hot and relatively dry. Daytime temperatures during this season typically range from 30°C to 35°C (86°F to 95°F), with occasional spikes above 35°C (95°F). Nights are cooler, with temperatures ranging from 15°C to 20°C (59°F to 68°F). While Tehran’s altitude mitigates some of the extreme heat, it can still experience heatwaves during the summer months.
  • Autumn (September to November): Autumn is a transitional season marked by gradually decreasing temperatures. Daytime highs range from 20°C to 30°C (68°F to 86°F), while nighttime lows drop to 10°C to 15°C (50°F to 59°F). The crisp, clear skies and cooler weather make it an attractive time for outdoor activities and sightseeing.
  • Winter (December to February): Winters in Tehran are cold and occasionally snowy. Daytime temperatures typically range from 5°C to 10°C (41°F to 50°F), while nighttime lows can drop below freezing, ranging from -5°C to 2°C (23°F to 36°F). Snowfall is common in the city, especially in the northern and western parts of Tehran, which are closer to the mountains.
  • Spring (March to May): Spring is a season of renewal in Tehran, with gradually warming temperatures. Daytime highs range from 15°C to 25°C (59°F to 77°F), and nighttime temperatures hover between 5°C and 15°C (41°F to 59°F). This season is characterized by blossoming flowers and lush greenery.

Tehran’s climate provides a distinct experience of all four seasons, making it a city where residents and visitors can enjoy a wide range of weather conditions throughout the year.


Tehran experiences a semi-arid climate with a pronounced dry season and a relatively modest amount of annual precipitation. Precipitation patterns in the city are influenced by its location in a rain shadow, created by the Alborz Mountains to the north.

  • Dry Season (May to October): The dry season in Tehran spans from May to October. During this period, the city sees minimal rainfall, and precipitation is rare. Rainfall totals during the dry season are often negligible.
  • Wet Season (November to April): The wet season in Tehran typically begins in November and extends through April. The majority of the city’s annual rainfall occurs during this time, with the wettest months being December and March. Rainfall totals during this season range from 30 to 60 millimeters (1.2 to 2.4 inches) per month.

The Alborz Mountains to the north of Tehran block the moisture-laden air masses from the Caspian Sea, resulting in a rain shadow effect. As a result, the city receives significantly less precipitation compared to regions to the north of the mountains.


According to existingcountries, Tehran’s climate features four distinct seasons, each with its unique characteristics:

  1. Summer (June to August): Summers are characterized by warm to hot weather, clear skies, and relatively low humidity. It is a season when many residents head to the cooler mountains or engage in indoor activities during the hottest parts of the day.
  2. Autumn (September to November): Autumn brings cooler temperatures, clear skies, and pleasant weather for outdoor activities. The season is marked by the changing colors of the trees in the city’s parks and gardens.
  3. Winter (December to February): Winters are cold, with occasional snowfall in parts of the city. The Alborz Mountains provide an opportunity for winter sports enthusiasts to ski and snowboard in nearby mountain resorts.
  4. Spring (March to May): Spring is a rejuvenating season with mild temperatures, blooming flowers, and a sense of renewal. It is an ideal time for exploring the city’s gardens and outdoor attractions.

Climate-Related Characteristics:

Tehran’s climate has some notable characteristics and considerations:

  1. Altitude: Tehran’s elevation, at over 1,100 meters (3,600 feet) above sea level, contributes to its cooler temperatures and mitigates some of the extreme heat during the summer months.
  2. Air Quality: Tehran often faces air pollution challenges, particularly during the winter months when temperature inversions trap pollutants in the city’s basin. Efforts to address air quality issues include measures to reduce vehicle emissions and promote public transportation.
  3. Mountain Proximity: The Alborz Mountains provide an attractive backdrop to the city and offer recreational opportunities such as hiking, skiing, and mountaineering. However, they also influence Tehran’s climate, blocking moisture and creating a rain shadow effect.
  4. Water Scarcity: Tehran faces water scarcity challenges, with its water supply relying on limited local resources and sources from neighboring regions. Sustainable water management practices are essential to address this issue.

In conclusion, Tehran, Iran, experiences a semi-arid continental climate with four distinct seasons, offering a wide range of temperatures and weather conditions throughout the year. The city’s climate is characterized by hot summers, cold winters with occasional snowfall, and mild transitional seasons. While it faces challenges such as air pollution and water scarcity, Tehran’s climate provides opportunities for outdoor activities, winter sports, and enjoying the beauty of all four seasons. Efforts to address climate-related issues and promote sustainable practices are crucial for the city’s long-term resilience and environmental health.
