Winter, from December to February, is quite mild. When the westerlies prevail, Atlantic disturbances bring mild and rainy weather, sometimes windy: in these cases, the temperature can reach and even exceed, 15 °C (59 °F). However, when a high pressure area dominates, fog can form at night, and there may be slight frosts, while during the day the temperature becomes quite mild, and the sun comes out. On the contrary, when the wind blows from Russia, there can be cold waves, with snowfalls, usually not abundant. The temperature rarely drops below -10 °C (14 °F), although the coldest record is -16 °C (3 °F), set in January 1985 and January 1987.
