White Christmases in Switzerland: Increasingly Rare on the Plateau
Table of Contents
While often envisioned with snow, white Christmases are becoming less common in many parts of Switzerland, particularly on the Plateau, according to long-term meteorological data.
The Plateau’s shifting Christmases
In many people’s minds, Christmas is associated with a landscape covered in snow. On the Swiss Plateau, however, white Christmases have long been exceptions, as statistics show. Since measurements began in 1931, the Central and Eastern Plateau has experienced snow cover on Christmas (December 24-25-26) only four years out of ten.
This means that six years out of ten, the Plateau regions have seen green Christmases, deviating from the traditional snowy image. The data, compiled by MeteoSwiss, highlights a clear trend towards less frequent snowfall during this period.
Regional Variations: West and Northwest Switzerland
The situation is even more pronounced in the west and northwest of the country. Here,white Christmases are rarer still,occurring only three years out of four. this suggests a stronger influence of weather patterns in these regions, leading to warmer temperatures and less snowfall during the Christmas period. MeteoSwiss data confirms this regional disparity.
A Different Story in the Mountains
The mountainous regions of Switzerland,however,tell a different story.Davos, a popular resort in the Grisons region, has experienced a Christmas Eve without snow only once as 1931 – on December 24, 2016. Even then, snow returned quickly, with a 3-centimeter layer covering the resort on December 25, 2016, as reported by MeteoSwiss.
This contrast underscores the meaningful impact of altitude on snowfall patterns. Higher elevations generally experience colder temperatures and increased precipitation, making white Christmases more reliable.
Historical Data: Snow Cover Frequency (1931-Present)
The following table summarizes the frequency of snow cover during the Christmas period (December 24-26) in different regions of Switzerland, based on data from MeteoSwiss:
| Region | Years with Snow Cover (out of 10) |
|---|---|
| Central & Eastern Plateau | 4 |
