Significant wave height: observed value (blue), wave forecast value calculated by the wave model (red). When the buoy is not in the sea or the observation data is not available for other 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 direction.
Finnish Meteorological Institute has four buoys in the Baltic Sea. These wave buoys are located in the Northern Baltic Proper, off Helsinki, in the Bothnian Sea and in the Bay of Bothnia. The buoys are removed before the sea freezes and redeployed in the spring when the ice has melted.
