Climate indicators

The significant rise in temperature during the past decades is not the only sign of climate change. Many other climate indicators help illustrate the climate and its alterations. The most important of these parameters can be depicted in chronological progression for climatologically relevant measuring stations.

Climate indicators are available for the most important stations of the Swiss climatological network. To the extent available, they are calculated for the periods from 1864 until present and 1961 until present using homogenised data. The graphic charts are updated about one month after the end of a season.



For historical reasons, one day lasts from morning to morning (05:40 am -05:40 am UTC) in the context of precipitation. For the other parameters, one day coincides with the calendar day (00:00 to 00:00 UTC). The time series are not available for all possible combinations of climate indicator, season, period and station. An indicator is not depicted if the required meteorological parameter is not measured at the station or if the indicator always has the same value, for example zero. Dog days never occur at high altitudes and therefore, they are not illustrated at these stations. Non-selectable combinations are greyed out in the selection menu.

Data quality

Homogenous climate data are used whenever possible. Homogenous climate data are adjusted for effects that are not related to climate and climate change. No homogenous series are yet available for snow and indicators that are based on the duration of sunshine; they are evaluated by means of the original data.
