The consistent rainfall and temperate conditions make this area one of the most fertile and green parts of the country, truly showcasing a distinct aspect of what is the climate in Iran.
Arid and Hot: The Western and Southwestern Deserts
Moving away from the Caspian Sea, a significant portion of Iran, particularly the western and southwestern areas, can be classified as a BWh climate. This is a hot, dry desert climate with annual average temperatures above 18°C. These regions are characterized by extreme heat, very low precipitation, and vast desert landscapes. The aridity is a defining feature, leading to sparse vegetation adapted to harsh conditions.
Furthermore, a small zone between the Persian Gulf and the Turkish border in the mid of Iran can be classified as a BSh climate. This is also a hot, dry climate, with the annual average temperature above 18°C, but it typically experiences slightly more precipitation than the BWh desert climate, often in the form of steppe conditions. Meanwhile, the central regions are lying within the zone of continental and mountainous weather, characterized by cold winters and hot, dry summers, further illustrating the complexity of what is the climate in Iran.
