Iceland is far from being as cold it´s name would suggest or as cold as many people would assume. This is primarily due to a branch of the Gulf Stream which flows along the southern and the western coasts of the country and drastically moderates the climate. As a result, the winters are relatively mild for an island of this northern latitude. On the other hand, summers are rather cool.
