The climate of Iran
Iran is one of the largest countries in the southern part of Asia.
Despite the fact that it is such a large country and the relief in
large parts of former Persia not as many climate types occur here as
one would expect. Apart from the northwestern tip which has a warm
continental climate the largest part of Iran has a mixture of four
arid climate types (B-climates according to the Köppen climate
classification). The lower regions along the coast have a warm desert
climate which changes into a warm steppe climate (type Bsh) on the
latitude of the Zagros mountain range. Central Iran has a cold steppe
climate (type Bsk) and locally a cold desert climate (type Bwk). The
Elbrus mountain range can be found in the northern part of Iran, here
precipitation figures may be high. The northern strip along the
Caspian Sea has a remarkably mild climate in comparison to the
surrounding areas. During the winter subzero temperatures are uncommon
here while subzero temperatures during the night may be recorded in
the capital Teheran which is located further to the south. Even during
the day subzero temperatures may occur here.
Climate information of places and areas in Iran
The climate information on this page is only brief. Specific
information about weather and climate can be found on the climate
pages per area or town. As for Iran the following climate
information is available:
Summers in Iran are warm to hot. During the hottest months the sea
normally has a cooling influence. However, in Iran the opposite seems
to happen. During the summer it is especially very warm in the
southwesterly and southeasterly coastal areas. Temperatures during the
day are often above 35 degrees Celsius (95 degrees Fahrenheit). In
some places temperatures of 35-40 degrees Celsius (104-113 degrees
Fahrenheit) are not uncommon during the hottest months. During the
summer the temperature of the Persian Gulf also increases. In June and
July the temperature of the water is 30-32 degrees Celsius (86-89.6
degrees Fahrenheit) making this one of the warmest seas in the world.
Summers are not only warm they are also very dry. Especially in the
southeastern part of Iran it may not rain for several months in a row.
The climate of Iran has large extremes. Snow and locally very cold
winters, regions with extreme drought and in the east very fierce
winds with hurricane strength. Especially in the mountainous regions
weather conditions may occur that make it hard for human and animal to
move. Roads completely covered with snow during the winter, high
temperatures during the summer and fierce winds which may cause very
dangerous situations. Especially during dry periods when a lot of sand
and dust is picked up by the wind.
Throughout Iran several climate figures and temperatures can be
recorded. The figures below are for the capital Teheran and cannot be
seen as an average for the country. For climate figures for other
places and regions in Iran please, visit the individual climate pages.
More climate information
Climate tables are useful but they don’t give an overall picture of
the climate and possible weather conditions during a period of time.
How high the chances are of hot or cold weather or hurricanes can
often not be found in these tables. This is why we offer extra climate
information per month. The figures below are for the capital Teheran.
