What to expect of weather

 | Post date: 2017/02/28 | 

Climatically, Zanjan province, being under the influence of indirect air-currents, named as humid north-western ones, enjoys two different types of climate. A mountainous climate with cold and snowy winters, and temperate summers. Whilst the Tarom Olya region experiences a warm and semi-humid climate with warm summers and mild winters. The percentage of rainfall and humidity is always higher than the mountainous terrain, the spring and winter seasons have more rainfall than other periods of the year. 

There are long spells of 'dry' months in the province and two of the most important air-currents are the 'Sormeh' and 'Garn' or in other words 'Harah' and 'Warm'. The most suitable seasons are spring and summer for spending time in this province regarding sight-seeing.

Climate
Zanjan has a cold semi-arid climate with hot, dry summers and cold, moist winters, often with snowfall. Precipitation is very low, and mostly falls between October and May.
