Hydrological situation and forecasts

The environment.fi website will be renewed

The renewed environment.fi website will be published by the end of March

The renewed environment.fi website will be published in the last week of March. The most important changes of the renewal concern the content. Environment.fi has implemented new functionalities that improve the user experience. The look of the site has also been renewed and the publication system has changed. This means that the vast majority of the current environment.fi addresses will change, but the important shortcuts will continue to work. Read more

Hydrological observations

Watershed forecasts for lakes and rivers on map (In Russian)

Hydrological forecasts

Hydrological watershed models systems cover the whole of Finland, including transboundary drainage basins. These models provide forecasts of flows and water levels (including flood forecasts) for more than three hundred locations. Real time hydrological maps are also produced, as well as comprehensive sets of hydrological data used for the purposes of flood prevention, water level regulation, pollution load calculations, and public information.

Hydrological observations

Current hydrological information is available from measuring sites all around Finland. These figures include the results of the latest hydrological observations. In many cases observations are recorded on a daily basis. Historical hydrological observations are available to download from SYKE Open information.

Satellite measurements

For the hydrological features satellite measurements can reveal such information as the extent of snow cover, sea surface temperature, and the presence of intense algal blooms. Snow cover is monitored from March to May in more than 5,000 drainage basins around Finland. Sea surface temperatures are recorded for the Baltic Sea and Finland’s largest lakes from May to October. Water turbidity and chlorophyll-a concentration in the Baltic Sea are monitored from April to October. Algal blooms in the Baltic are monitored in July and August. The results of all these satellite measurements are combined into thematic maps on a daily basis, although clouds may partially cover the observed area and prevent satellite observations. 

Other current information

The Finnish Environment Institute (SYKE) also publishes occasional pressreleases on floods, snow cover, and other important news related to water and snow information.
