Riviera is an Italian word that originates from the ancient Ligurian territory of Italy, wedged between the Var and Magra rivers. Côte d'Azur is originally a nickname given by France to the County of Nice after its annexation in 1860, because the climate was similar to that of the north of Italy, even in winter, with "a sky as blue as its sea". When the Mistral (Northwest) and the Tramontane (North) winds are blowing in the Languedoc and Provence areas, the temperature of the Mediterranean can be very cool in summer. This phenomenon is observed very little or not at all on the coast between the French Riviera and the Italian Riviera.
