Data and statistics

SMHI has access to a comprehensive database with a long series of day-to-day observations from weather stations throughout the world. From the database, weather statistics are customised based on your requirements and needs for the best possible decision-making information. Read more about how we can compile climate data for each parameter, or contact us so that you can choose the parameters and stations or find out what it costs.

Products

Temperature

– what will the temperature be like? Our temperature products include, among other things, time series, mean and normal values, frequency tables, temperature maps and estimates of duration and return periods. Temperature

Wind

– what does the wind climate look like? SMHI supplies data series, wind roses, frequency tables, return times, storm maps and information for the development of wind power. Wind statistics

Solar radiation

– how often does the sun shine? Receive data from SMHI's solar radiation stations, or calculate the values for any point with the STRÅNG model. Solar radiation

Snow depth

– how does snow coverage usually disperse? Many of SMHI's stations measure the depth of snow coverage. Data can be presented in table or map form. Snow depth

Data from stations abroad

– weather from the whole world Through cooperation with metrological institutes throughout the world, SMHI has access to data from many measuring stations abroad. Data from stations abroad

Precipitation

– what does the pattern of precipitation look like? Mean precipitation, extremes, frequency distribution and return time are presented in table form, maps, graphs and reports. Precipitation

Air humidity

– how does air humidity vary? We provide compilations of outdoor air humidity for relative and absolute humidity levels, the mixture ratio and dew point. Air humidity

Visibility

– how far can you see? We show the variation in visibility over a period of 24 hours, a season and longer periods in clearly displayed tables and maps. Visibility

Ice development on masts

– how prevalent is icing? Knowing how often icing takes place on masts and wind power installations is important from a dimensioning and safety point of view. Ice development on masts
