Climate in St Pierre Miquelon

The climate of Saint Pierre and Miquelon, a French overseas collectivity, is cold oceanic, with cold winters, in which the temperature is often below freezing, and mild summers. Saint-Pierre and Miquelon is a small archipelago located south of the Canadian island of Newfoundland.
We are in an area where the clash between sea and air currents (the Gulf Stream and the mild wind from the south-west on one side, the Labrador current and the cold wind from the north on the other) gives rise to frequent rains (and snowfalls in winter) but also to frequent fogs. In addition, the islands are windy.
Due to the lack of mountains and rivers, there is a certain scarcity of water available, so water is collected from rain, desalinated from the sea or produced by an incinerator.
