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.
From August to October, the archipelago can occasionally be hit by hurricanes of the Atlantic, which, after affecting the Caribbean, turn north-east. They generally arrive weakened because they have to cross a cold sea, however they can still bring abundant rains and strong winds.
On the coldest days of the year, the temperature can drop to -10/-14 °C (7/14 °F) or even below. In February 1994, it dropped to -17 °C (1.5 °F). On the warmest days of the year, in general the temperature does not exceed 23/24 °C (73/75 °F), even though the record is 28.5 °C (83 °F).
The average temperature of the coldest month (February) is of -3.2 °C (26 °F), that of the warmest month (August) is of 16.3 °C (61 °F). Summer is particularly cool because of fogs. Here are the average temperatures of the capital, Saint-Pierre.
