Côte d'Azur, France

French Riviera benefits from 310 to 330 days of sunshine per year.
Riviera is an Italian word that originates from the ancient Ligurian territory of Italy.  The Côte d'Azur (coast of azure) is 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.
This coastline was one of the first modern resort areas. It began as a winter health resort for the British upper class at the end of the 18th century. With the arrival of the railway in the mid-19th century, it became the playground and vacation spot of British, Russian, and other aristocrats, such as Queen Victoria, Tsar Alexander II and King Edward VII, when he was Prince of Wales.
Officially, the French Riviera is home to 163 nationalities with 83,962 foreign residents in 2017, although estimates of the number of non-French nationals living in the area are often much higher.
According to the Côte d'Azur Economic Development Agency, each year the Riviera hosts 50 percent of the world's superyacht fleet, with 90 percent of all superyachts visiting the region's coast at least once in their lifetime.Read more
