Abstract

Visual wave observations from the north-eastern coast of the Baltic Proper and from the southern coast of the Gulf of Finland and numerically hindcast wave properties for the entire Baltic Sea were used for the identification of combinations of wave heights and periods in extreme storms and long-term changes in extreme wave heights and wave propagation directions. The extreme wave heights and periods are about 7 m and 10–12 s in the northern Baltic Proper, about 6 m and 8–11 s at the entrance to the Gulf of Finland, and about 4 m and 6–8 s in the eastern part of this gulf. Wave hindcasts show no statistically significant trends in the 95%-iles and 99%-iles of the wave heights. Significant observed changes in the directional distribution of waves at Narva-Jõesuu from the 1980s are not represented in hindcasts.

Keywords
