In the north of Spain you find an Atlantic climate with mild summers and winters. The sailing conditions, especially in autumn, can be sometimes very rough, especially in the Bay of Biscay. The south of Spain is characterized by the Mediterranean climate, the summers are very warm and the winter pleasantly mild. Especially in the summer months, the area around the Balearic Islands and the Spanish Mediterranean coast is considered to be slightly windy and in the early afternoon a thermal wind regularly occurs. From the northwest, however, sometimes a strong wind can be felt, the so-called Tramontana.
