The range of sea level heights depends on the location

The water level is reported in the meters according to the N2000 system, which is the common European height system. The water level readings differ by 13-43 cm compared to the older N60 height system, mainly due to land uplift.

Water level height as a timeserie

By clicking the station on the map, list or diagram, the last 2 weeks observations can be seen. The water level values on a map are presented in theoretical mean water. On the map, setting the mouse on a station shows the last 24 hours sea level observations. The values are presented in theoretical mean water. The description of different height systems can be found in Finnish meteorological institutes webpages(siirryt toiseen palveluun).

On the diagram, setting the mouse on a station shows the latest observation and as a grey column the extreme sea levels measured on that station.
