The northern strip of Iran, marked with green on the map, by the Caspian sea, is  the most popular domestic summer destinations. While the country is hot and dry through out the summer this narrow strip between the high rising mountains and sea is very mild and cool.

The blue locations on the map are the mountains and their skirts. Most Central cities in Iran are located on mountain skirts. The north west cities such as Tabriz and Urimie are very cold through out winter with pleasant summers. If  we journey towards the south, the temperatures rise . Tehran has very mild weather in summer and winter. Yazd and Isfahan and further south, Shiraz are located in the central Iran which have cool winter and very hot summers. The sun is very strong in central Iran.

The south of Iran has very humid hot weather. Winters are very pleasant. Iranians travel to the south of Iran in winters, specially kish and Gheshm Island have the best weather in winters.

Based on average annual rain fall, Iran is a dry, semi-dry country. The average rain fall is 275mm per year, which ranges from 2m to 5cm throughout the country.

Being prepare for Iran’s climate

Sun glasses, the most important piece you will need.

If your traveling in winter, unless you plan to visit the southern islands of Iran bring light winter wears ( you wont need very very warm coats in Iran).

If your traveling in summer, be sure to bring very cool cotton cloths ( Iran men and women have to be covered) since it is gonna be hot. Packing sun block and a hat will also be a good idea.

In Spring and Autumn weather can be unpredictable so pack a cool set of cloths and a warmer set of cloths including a coat.

Central parts of Iran can also be quite dry, a small bottle of body lotion may come in handy.
