Sea levels & waves

Positions where sea levels or significant wave height are measured in the Baltic Sea area are shown on the map. By clicking one of the dots or by using the drop down list, time series of observations and forecasts are shown in a diagram and table.

Information about the service

In the map, the last observation in all position is represented by a colour according to the legend below the map. If SMHI has issued a sea level warning for any area, this is marked with a background colour according to the legend.

Compare observations

Click on Compare observations to see the last 24 hours of data at the chosen stations. The result is presented in a Table.

Chose station and forecast length

By clicking one of the dots in the map or by using the drop-down list, time series of observations and forecast from the station are shown in a diagram or table. You can chose to look at data for at shorter time period or longer period by selecting time span.

The forecasts in the service

The ocean circulation model that is used to make the sea level forecasts presented in the service exist in two horizontal resolutions. The different setups can result in different forecasts.

Short forecast: The forecast called "Short forecast" in the diagram is from a model with a resolution of 1 nautical mile. It provides 60-hour forecasts.

Long forecast: The “Long forecast” is from a model set up with a 2 nautical mile resolution that provides longer projections.

Wave forecast: The forecast displayed for waves is from a wave model. It is available in one set up and is called "Wave forecast" in the diagram.

Observations from different sources

Beside measurements made by SMHI, observations that are owned or supplied by other data providers is shown in the service. For each station this is show under the name in the diagram. The used height system is shown in the diagram/table as well. All Swedish stations use RH 2000.

Denmark: DMI - Danish Meteorological Institute

Germany: BSH - Bundesamt für Seeschifffahrt und Hydrographie, WSA – Wasserstraßen- und Schifffahrtsverwaltung des Bundes
