Winters are generally cool, wet, windy and overcast. During this season, there are bursts of icy and relatively dry winds of continental polar air masses, giving an unpleasant chilly feeling to the everyday life of the city. Frosts occur few times during winter, generally not falling below  because of the oceanic influence that moderates the temperature; a few kilometres inland, frosts are more common and colder. Rainfall and sleet are a frequent winter occurrence, but snowfall is extremely rare: flurries have been recorded only four times but with no accumulation, the last one on 13 July 1930 during the inaugural match of the World Cup, (the other three snowfalls were in 1850, 1853 and 1917); the alleged 1980 Carrasco snowfall was actually a hailstorm.
