Cannes bay is located between Pointe de l'Aiguille and Cap de la Croisette, 4 miles ENE, from which the islands "Les Îles de Lerins"  extends up to 2 miles. The E side of the gulf is occupied by the town and port of Cannes well known by it's film festival, where the houses form a semicircle along the shore.

The  winds are generally from between the W and N in winter. The famous Mistral from NW  is strong. In summer, winds from the E and W prevail.

La baie de Cannes s'étend de la Pointe de l'Aiguille aux îles de Lerins Sainte-Marguerite et Saint-Honorat. Elles offrent des promenades uniques sur le littoral des Alpes-Maritimes pour leur calme et leur densité forestière. Le passage du Frioul, qui les sépare, est un des mouillages de prédilection des navigateurs de plaisance. Les fonds sous-marins sont très riches en flore et en faune.
