Iran is one of the few countries in the world which has a diverse four-season climate. However, its climate is generally dry. Almost all precipitation falls between November and March during the winter, much of it in the form of snow. Rainfall varies from season to season and from year to year. Winters are mild in the north and warm in the south. Elsewhere, January temperatures average near or below freezing. Summers are usually very hot except in the mountains.
Evergreen forests and stunning lakes cover northern parts of the country while its southern regions are characterized by gorgeous and good-looking palm trees. The country’s eastern parts enjoy a hot desert and running sand and its western regions are filled with high mountains.
