Because of its high elevation and its distance to the sea, the climate is harsh.  Summers are short, hot and dry, and winters are long, snowy and very cold. 
There is a large shift between day and night time temperatures.  Spring and 
fall are rainy and mild. The coldest temperatures in the country are recorded 
here at, (-43⁰-45⁰)  degrees centigrade... The mean temperature in this land 
that belongs in the terrestrial climate region of Turkey is 6.1⁰ centigrade.

The air in Igdir, which is on the northern slopes of the mountain, is hazy and 
cold.  Dogubeyazit, on the other hand, which is situated on the southern slope, 
boasts of clear skies and warm weather.  On days when one needs a heavy 
coat in Igdir, in Dogubeyazit, one can enjoy a walk under clear and sunny 
skies wearing just a shirt.

Ararat Mountain creates its own weather conditions; meteorological broadcasts are 
not to be trusted.  The peak is visited frequently by harsh winds, and weather 
can change in a split second. Every year several deaths are reported due to 
changing weather conditions prevailing on the mountain. One needs to be 
prepared and not overly insistent about climbing to the top.

In summer, the glacier on the peak is subjected to bright sun in the day time 
and below freezing temperatures in the night. The ice is glass-like.  If 
the temperatures are mild in the day, footing may become softer, but in all 
conditions one needs to wear crampons. When the conditions are for glass-ice, crampons are not sufficient; and rope stations have to be established.  One of 
the best known mountaineers has lost his life for this reason.. Some times if 
there is snow-fall at night, conditions become better for the climb to the peak.

The winds at the peak are so fierce and cold that regular gortex mountaineering 
coats are like a sieve offering no protection.  One can be frozen in ten minutes 
in a bona-fide storm.  One has to stay home under such extremely windy 
conditions, or be heavily protected.  Of course, proper clothing does not stave 
off all the danger, because there is always the danger of losing ones balance 
and falling off the glacial passes.

If you want to climb in winter you should know that you have to carry all your equipments and all services fee wiil be doubled.

Best season for ski from top is May.

Every 30 Agust there is a traditional climb. People aimed to be in top on 30th Agust. So be aware to go 28 Agust-02 Sep. Because hundreds of mountainer will be there and not enough space for tents.

Climate of Turkey

Although Turkey is situated in large Mediterranean geographical location 
where climatic conditions are quite temperate, diverse nature of the landscape, 
and the existence in particular of the mountains that run parallel to the coasts, 
result in significant differences in climatic conditions from one region to the 
other. While the coastal areas enjoy milder climates, the inland Anatolian 
plateau experiences extremes of hot summers and cold winters with limited 
rainfall.

The Aegean and Mediterranean coasts have cool, rainy winters and hot, 
moderately dry summers. Annual precipitation in those areas varies from 580 
to 1,300 millimeters, depending on location. The Black Sea coast receives the 
greatest amount of rainfall. The eastern part of that receives 2,200 
millimeters annually and is the only region of Turkey that receives 
rainfall throughout the year.

Turkey's diverse regions have different climates because of irregular 
topography. Taurus Mountains is close to the coast and rain clouds cannot 
penetrate to the interior part of the country. Rain clouds drops most of their 
water on the coastal area. As rain clouds pass over the mountains and reach 
central Anatolia they have no significant capability to produce of rain. In the 
Eastern region of Anatolia, the elevation of mountains exceeds 2500-3000 m. 
Northern Black Sea Mountains and Caucasian Mountain hold the rain clouds, 
and therefor the area is affected by the continental climate with long and very 
cold winter. Minimum temperatures of -30°C to -38°C are observed in 
the mountainous areas in the east, and snow may lie on the ground 120 
days of the year. Winters are bitterly cold with frequent, heavy snowfall. 
Villages in thee region remain isolated for several days during winter storms.

ANNUAL AVERAGE PRECIPITATION OF TURKEY

Summers are hot and dry, with temperatures above 30°C. Spring and autumn 
are generally mild, but during both seasons sudden hot and cold spells 
frequently occur in the region Annual precipitation averages about 500-800 
millimeters with actual amounts determined by elevation.

LONG TERM MEAN TEMPERATURE OF TURKEY

In Istanbul and around the Sea of Marmara the climate is moderate (winter 
4°C and summer 27°C); In winter however the temperatures can drop below 
zero. In Western Anatolia, there is a mild Mediterranean climate with average temperatures of 9°C in winter and 29°C in summer. On the southern coast of 
Anatolia the similar climatic condition are observed. The climate of the 
Anatolian Plateau is a steppe climate. 
There is a great temperature difference between day and night. Rainfall is low 
but it usually in form of snow. The average temperature is 23°C in summer 
and -2°C in winter. The climate in the Black Sea area is wet, and humid 
(summer 23°C, winter 7°C). In Eastern Anatolia and South-Eastern Anatolia 
there is a long winter, and snow remains on the ground from November until 
the end of April (the average temperature in winter is -13°C and in summer 
17°C).

The driest regions are the Karaman, Iğdır and Şanlıurfa, where annual 
rainfall frequently is less than 300 millimeters. The wettest regions are the 
Black Sea coastal region where annual rainfall can reach 2,200 millimeters 
annually, and the region receives rainfall throughout the year.
