The monthly and annual maps show the monthly and annual averages of the temperature, precipitation, hours of sunshine and global radiation. The deviations of the current climate values from the long-time average, the normal values, are additionally illustrated. Consequently, the maps supply important climate-related information that is recognizable at a glance for all regions of Switzerland.
Monthly and annual maps
The graphic charts are updated regularly in accordance with the existing data quality. Precipitation details are tentative until the 26th day of the following month and may not yet be complete. Global radiation data are available several days after the end of the month.
The deviations for the temperature, precipitation and hours of sunshine are shown in comparison to the long-time average, the so-called normal values, from 1981-2010. The deviations of the global radiation relate to the average values from 2004 until present. The respective weather pattern for the month, season and year is described extensively in the climate bulletins; they can be retrieved under climate reports.
Temperature deviation in February 2014
The map shows the temperature deviation in February 2014 from the average of the years 1981-2010 for every location in Switzerland. As an example, the temperature during this month was 2-3°C higher than the long-time average in the central area, while the deviation in large parts of the Canton of Ticino ranged between -0.5°C and +0.5°C .
Acquisition of grid data
Grid data in different chronological and spatial resolutions can be obtained from the weather service MeteoSwiss. Detailed information about the grid data, grid method and available products can be found under Service & Publications.
