Weather in Iran

Expats living in Iran will have to contend with its semi-arid climate where the summers are long and hot, and the winters short and cool, while the north is a subtropical region.

While it is typically hot and dry, Iran also has subfreezing temperatures and heavy snowfall during winters, especially in the northwest, and a steady rainfall throughout the year along the Caspian Coast.

Spring in Iran coincides with Norwuz, the Persian New Year, and lasts from March to May. This time of year is cool, with temperatures rapidly rising towards summer. Spring is a relatively short season and expats can expect fluctuating weather patterns with some rain too.

Summer in Iran is the longest season and lasts from late May to September. It is hot and dry except on the Caspian Coast where rainfall starts as early as mid-summer and lasts through to winter’s end. Summer highs rarely exceed 84°F (29°C) in most of the country, but temperatures rise as high as 100.4°F (38°C) in the east and its desert areas.

Autumn in Iran is short, lasting from October to November. Temperatures begin to drop and rainfall arrives in most parts of the country by November. 

Winters in Iran are cool, especially in the northwest where it drops below freezing and snows, often heavily. From December until mid-March, the weather will remain cool, below 50°F (10°C) and sometimes below 32°F (0°C), and this is the wettest time of year.

A major concern for expats is the combination of humidity and heat. Heat exhaustion is a threat to unprepared or sickly residents and can be fatal. In addition, sudden violent storms can cause property damage and injury – a dust storm in the capital, Tehran, in 2014 resulted in several fatalities. There are also frequent earthquakes in Iran and these are often both damaging and lethal, especially when occurring close to the capital area.

Two final environmental considerations for expats include pollution and water security in Iran. The level of pollution in cities like Tehran will adversely affect those with sensitive respiratory systems and water availability is a pressing current and future challenge.
