Facts and figures

Important note

The content of this page is based on the Swiss climate scenarios CH2018. In the meantime, the new Swiss climate scenarios have been published as part of the Climate CH2025 project. They expand on the previous results with longer measurement series and information from new, high-resolution climate models. The qualitative statements remain unchanged from the CH2018 climate scenarios, but the quantitative estimates have changed. It is recommended that the results of Climate CH2025 be used.

Climate CH2025

Switzerland as a whole

Global climate change does not stop at Switzerland's borders. The extent of the change will depend on how greenhouse gas emissions develop worldwide. Here you get an overview of how temperature, precipitation and various climate indicators will change throughout Switzerland by the end of the century with and without climate change mitigation.

Temperature

The temperature in Switzerland will continue to rise in the coming decades. Here you will find information on temperature changes as annual averages, seasonally and as high-resolution maps, with and without climate change mitigation.

Precipitation

Future climate change is also evident in terms of precipitation. Over the course of this century, an increase in winter precipitation can be expected throughout Switzerland, while summer precipitation is likely to decrease. Learn everything about the seasonal trends in precipitation in the form of time series and high-resolution maps with and without climate change mitigation.

Climate indicators

As average temperatures rise, summer days and tropical nights will increase significantly. Conversely, days with frost or snowfall will decrease in the lower-lying areas. Here you can find high-resolution Swiss maps showing how many summer days, tropical nights, frost days and fresh snowfall days can be expected around the middle of the century with and without climate change mitigation.

Major Swiss regions

Climate change manifests itself differently in the various regions of Switzerland. This page provides an overview of the future changes in temperature, precipitation and various climate indicators for the major Swiss regions of the Jura, the Swiss Plateau, the Alpine foothills, the Alps and the south side of the Alps.
