Switzerland: Warmest Christmas Eve in over 100 years
In Switzerland, temperature records tumbled at numerous measuring stations on December 24th. Some of the stations have been in operation for over 100 years. The reason is a typical Christmas thaw.
According to this information, there were also high temperatures on Christmas Eve in the canton of Graubünden, for example in Poschiavo with 15.6 degrees. 8.9 degrees were measured at the Ofen Pass at an altitude of more than 2,100 meters.
The Christmas thaw pattern is common, SRF Meteo reported. When the polar night begins in Scandinavia at the end of November, a cold high forms and icy air often flows into Central Europe from the north. Because some of the cold air flows into the rather warm Atlantic, low pressure areas form, which often lead to thaws and significantly milder temperatures shortly before Christmas.
