Climate indicators - precipitation

The climate indicator for precipitation is based on measurements from 87 stations since 1860. As there are no stations in the mountainous areas with heaviest precipitation the values are slightly lower than a true average for the whole country.

Based on the moving averages it can be seen that precipitation was lower than 600 mm up until around 1920. Between 1920 and 1980 the precipitation was approximately 600 mm. Since then precipitation has increased. It is now very uncommon that average annual precipitation values are less than 600 mm.

Precipitation in the future

Precipitation in Sweden is expected to increase. By the end of the century the average annual precipitation will be 20-60% more than for the period 1961-1990, depending on which scenario is used.

Precipitation is expected to increase during all seasons, but mostly in northern Sweden and during the winter. During summertime the increase in southern Sweden is small. About half of all the climate model simulations show an increase in precipitation while the other half show a reduction, which is an indication that the change will be close to zero.

Precipitation can vary a lot from season to season. This means that there is a wide range of possible developments in the future. For each season there are climate model simulations that show little or no increase in precipitation by the end of the century.
