The French Riviera, known in French as the Côte d'Azur (French: [kot dazyʁ] ; Provençal: Còsta d'Azur, pronounced [ˈkwɔstɔ daˈzyʀ]; lit. 'Azure Coast'), is the Mediterranean coastline of the southeast corner of France. There is no official boundary, but it is considered to be the coastal area of the Alpes-Maritimes department, extending from the rock formation Massif de l'Esterel to Menton, at the France–Italy border, although some other sources place the western boundary further west around Saint-Tropez or Toulon. The coast is entirely within the Provence-Alpes-Côte d'Azur region of France. The Principality of Monaco is a semi-enclave within the region, surrounded on three sides by France and fronting the Mediterranean. The French Riviera contains the seaside resorts of Cap-d'Ail, Beaulieu-sur-Mer, Saint-Jean-Cap-Ferrat, Villefranche-sur-Mer, Antibes, Juan-les-Pins, Cannes, and Théoule-sur-Mer.
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.
