Iran’s climate is continental, with hot summers and cold, rainy winters; the mountain regions of the north and west have a subtropical climate.
Temperature and precipitation vary with elevation, as winds bring heavy moisture from the Persian Gulf.
The Caspian region receives over 40 in. (102 cm) of rain annually. Precipitation occurs mainly in the winter and decreases from northwest to southeast; much of the precipitation in the mountains is in the form of snow.
Meltwater is vital for Iran’s water supply.
The central portion of the plateau and the southern coastal plain receive less than 5 in. (12.7 cm) of rain annually.
