The east of Iran is dominated by large sand and salt deserts. Except for the strip of land bordering the Caspian Sea, Iran is an dry, arid country. The size of the country also leads to large variations. Summers are very hot, especially in the desert regions, and winters vary from mild to icy cold. The Persian Gulf is milder in winter but can be just as hot in the summer and is often very humid as well.
Conditions can be ideal for winter skiing in some mountain areas.
Bring light clothes during summer and warmer clothes during the winter. Expect rain in most places during the winter and spring. We advise you check your local consular advice for up to date security information before you travel. Most areas in Iran are safe for travel. Tensions here can rise suddenly however, following changes in local politics or the situation in the greater Middle Eastern region.
