"The islands of eternal spring” - also so-called are the Canary Islands. Trade winds determine the weather on these islands west of the African coast, which guarantees good weather with perfect tropical climatic conditions for almost a whole year. During the summer months it gets quite hot, the winter months are perfect for many Europeans leaving the European continent for a sunny, warm holiday. Full sun and almost always (cool) wind helps you getting out of your winter depression! There are slight climatic differences between the northern and southern islands: the North is located windward of the trade winds, so dark clouds and rainfall appear more often than in the South.
