The significant wave height: observations (blue), wave model forecast (red). When the buoy is not in the sea or observational data are not available for technical reasons, the results calculated by the wave model are shown in both the graph and the table (with magenta in the graph). The arrows show the wave propagation direction.
The Finnish Meteorological Institute (FMI) has four wave buoys in the Baltic Sea. They are located in the Northern Baltic Proper, in the Gulf of Finland, in the Bothnian Sea and in the Bay of Bothnia. FMI also operates a wave buoy that is moored outside of Suomenlinna, althought the buoy is owned by the City of Helsinki. Because the wave model is not yet able to produce reliable wave forecasts for this area, only the observations are presented.
The buoys are removed before the sea freezes and redeployed in the spring when the ice has melted.
