Current Climate


This page presents Switzerland's climate context for the current climatology, 1991-2020, derived from observed, historical data. Information should be used to build a strong understanding of current climate conditions in order to appreciate future climate scenarios and projected change. You can visualize data for the current climatology through spatial variation, the seasonal cycle, or as a time series. Analysis is available for both annual and seasonal data. Data presentation defaults to national-scale aggregation, however sub-national data aggregations can be accessed by clicking within a country, on a sub-national unit.  Other historical climatologies can be selected from the Time Period dropdown list. Data for  specific coordinates can be downloaded for in the Data Download page.

Observed, historical data is produced by the Climatic Research Unit (CRU) of University of East Anglia. Data is presented at a 0.5º x 0.5º (50km x 50km) resolution.

Climate conditions of temperature and precipitation patterns vary significantly across Switzerland, depending mainly on altitude and location. The Alps – running from south-west to east – act as a major climate divide. About one third of the relatively abundant precipitation occurs as snow.


  • Since the beginning of temperature measurements in Switzerland in 1864, the average annual temperature has risen by 1.75°C.


  • Precipitation trends are insignificant and changes in mean precipitation are less clear.
  • Since 1901 the intensity of the annual 1-day precipitation maxima has increased by about 12% and the frequency of the all-day 99th percentile events by almost 30% on average.
