In spite of being located at a similar latitude to the Bay of Biscay, the archipelago is characterized by a cold borderline humid continental/subarctic climate, under the influence of polar air masses and the cold Labrador Current. The mild winters for being a subarctic climate also means it has influences of subpolar oceanic climate, thus being at the confluence of three climatic types. The February mean is just below the isotherm for that classification. Due to just three months being above 10 °C (50 °F) in mean temperatures and winter lows being so mild, Saint Pierre and Miquelon has a Köppen Climate Classification of "Dfc", if bordering on "Cfc" due to the mildness of the winter and either "Dfb" or "Cfb" due to the closeness of the fourth-and fifth-warmest months to having mean temperatures at or above 10 °C (50 °F).
