Iran’s plateau enjoys a relatively dry climate. Its location on the global arid belt of Alborz and Zagros mountain chains traps the humidity and air currents of the Caspian Sea and Mediterranean and prevents their penetration to the inner parts.
According to Tarannomtour website, Iran enjoys considerable climatic changes due to its location between 25 and 40 degree latitude. The average annual temperature increases from northwest to southeast of the country and varies from 10 degree Centigrade in Azarbaijan to 25-30 degree Centigrade in the south and southeast. The northern and southern shores of Iran, in different seasons, have diverse climates, compared with central and mountainous regions. The average annual temperature of Bandar Abbas in the south of Iran in January is 18.5 degree Centigrade. The difference of average annual rainfall is also very high in different parts of the country. These changes vary from 2000 mm in Gilan to less than 100 mm in central parts of Iran. Average annual precipitation in Iran is 275 mm.
Diversity
Iran enjoys a considerable climatic diversity, experiencing various seasons in different parts of the country, in a way that in some areas, the coldness of winter and the warmth of summer can be simultaneous. Thus, the weather in Iran must be judged regionally.
In January and February, there are three climate zones in Iran. Shores of the Caspian Sea have mild and relatively cold weather, central parts with wintry weather and southern parts enjoy moderate and pleasant weather. The whole of Iran enjoys a pleasant weather in spring, especially in June. But the weather in southern parts grows very hot unexpectedly.
Climatic conditions of the country become complicated in summer. Due to high humidity, the weather of the coastal parts of Caspian Sea changes in summer. During the day it is hot, but it is relatively cool at night. Along the southern coastlines of Iran, the days are very hot and nights are relatively warm with very high humidity, which is intolerable to non-native residents.
The cities of Shiraz, Isfahan, Mashhad, Tehran and Tabriz, which are the main tourist centers of Iran, enjoy different climates. Shiraz, with four months of warm weather, takes first place and Tabriz with only one month of warm conditions is at the last spot. Azarbaijan, Kurdestan, Hamedan and Khorasan provinces are famous as cool places in summer.
The entire north of the country, especially the Alborz slopes like Noor Valley, Kelardasht and Katalem, as well as Azarbaijan, Khorasan and central regions of Zagros mountains between Tooyserkan and Golpayegan, has very suitable conditions for spending weekends and holidays by domestic as well as foreign tourists in summer. Tourists may visit the southern region of Iran, for 5-6 months of the year, especially in the fall and winter.
Those foreign tourists, who visit the southern coasts of Iran in winter, face a very pleasant weather. During this period, the cities of Isfahan and Fars provinces are rainy and snowy with a very cold weather. In summer, the weather in most parts of the country is warm but not intolerable. Spring and autumn, especially during Norouz holidays (the Iranian New Year starting March 21) are suitable for touring all parts of the country.

In the history of architecture, it is written that designs of minarets are different from other works of art.
Before the advent of the Islamic period, minarets inside urban areas were used as places where the Zoroastrian fires were lit. Caravans found their paths through the flames of the fire. Minarets were also used as watch towers to defend cities against enemy attacks. In the Islamic period, minarets helped people to locate mosques. Based on some reports, Isfahan’s Hakim Mosque originally had a minaret which was more than 100 meters high. Some historians attribute the destruction of the minaret to Moguls and some to army of Tamerlane.
Although minarets look like slim structures that seem unbalanced, they are very endurable. The reason behind their endurance is that snow and rain do not penetrate into them. The conic and cylindrical shape of minarets also makes them resistant against earthquake. An expert of Isfahan’s Cultural Heritage, Handicrafts and Tourism Department, Farshid Ebrahimnejad said that the highest number of minarets in the country is located in Isfahan, which hosts a total of 17.
“Since Isfahan was among the country’s biggest civilization centers in ancient times, it had many minarets during the reign of Seljuk and Safavid dynasties,“ he added.
He went on to note: “Minarets are typically located near mosque domes. Because of their height, architectural style and tile- and plaster-works minarets are structures that appeal a great deal to tourists.“
Ebrahimnejad noted that all 17 minarets of Isfahan have been registered as national heritage upon the collaboration of Iran Cultural Heritage, Handicrafts and Tourism organization (ICHHTO), which is doing its best for their registry at the United Nations Educational, Scientific and Cultural Organization (UNESCO) as world heritage.
He pointed out that the minaret of Imam Ali (AS) Mosque dating back to the fifth century AH, Sareban Minaret dating back to Seljuk era and the two minarets of Menarjonban dating back to the eight century AH have been renovated in contemporary times.
Minarets of Isfahan vary in design and architectural style depending on the era to which they belong.
“Minarets of Dar-ul-Ziyafeh are about 38 meters high while Baghooshkhaneh Minaret which belongs to Ilkhanid era is a unique edifice of the Islamic period with unmatched decorations. However, the minaret of Imam Ali (AS) Mosque of Harouniyeh dating back to Seljuk era is indeed the top minaret of all times,“ Ebrahimnejad commented.
Tallest Minaret
Sareban Minaret is 54 meters high and belongs to the Seljuk period.

Oldest Minaret
The minaret of Barsiyan Mosque is located some 42 kilometers to the east of Isfahan. It was built in 491 AH.

Menarjonban
The edifice consists of a mausoleum and two minarets. It dates back to the eighth century AH. The building’s veranda is an example of Mogul architectural style in Iran. Minarets were probably annexed to the structure during the reign of Safavids. When one minaret is moved not only the other minaret but also the whole building oscillates. Experts believe that there is dynamic equilibrium in all structures in symmetry with the minarets, what makes the equilibrium of the structure more detectable is attributed to slimness and lightness of the minaret. Tourists who come to Isfahan have always talked about similar structures in other parts of the world.
Menarjonban is located on Najafabad-Isfahan route and in a village called Karladan. Each of the minarets is about 17 meters high and the height of the edifice is 10 meters. Azure and turquoise tileworks decorate this building. In the lower section of the building there is the mausoleum of a clergyman, Amou Abdullah. A piece of marble lies on the grave, decorated with a verse from the holy Qur’an. There are also other inscriptions in the mausoleum describing Amou Abdullah as pious and virtuous.

Sareban
This minaret dates back to the Seljuk era. It is not very far from Chehel Dokhtaran Minaret, north of Jobareh. It seems that in the past there was a mosque near the minaret, but no remains of the mosque have been found in contemporary times. The building comprises of seven distinct sections. The first section includes rows of brickworks, the second and third sections are masterfully decorated with bricks, the fourth section includes crown of the minaret which has brick arches along with turquoise tiles, the fifth section has brick decorations, the sixth section includes the second crown of the minaret and the seventh section is the minaret’s peak. At the base of the two crowns of the minaret are two magnificent inscriptions decorated with exquisite turquoise tile-works.
The building is currently tilted toward the west. Experts do not know the exact date of the minaret’s construction. However, they believe that it belongs to between 650-680 AH.

Dar-ul-Ziyafeh
In the old neighborhood of Jobareh and on Avicenna Street there is an exquisite gate on top of which the two minarets of Dar-ul-Ziyafeh are situated. Experts maintain that the gate most probably belonged to a guesthouse used by local rulers or kings, but no traces of the guesthouse have been found as yet.

Chehel Dokhtaran
This is another famous minaret of Isfahan which is located in Jobareh neighborhood. The identity of this minaret is the most known among all minarets of Isfahan. The date on which the building was completed (501 AH) and the name of the person who endowed it (Abi-ul-Fath Nahouji) are inscribed in Kufi script.
