Winter, from December to February, is cold: the average temperature is slightly below freezing. Cold air stagnation in the lowest layers leads to many gray days, with snow typically light but quite frequent. On the other hand, cold air masses of Siberian origin can lead to intense frosts, with temperatures plunging below -20 °C. Here are some values recorded in particularly cold winters: February 1940: -29 °C; February 1956: -28 °C; January: 1985: -25 °C; January 1987: -24 °C; December 1996: -23 °C; February 2012: -22 °C.
