These big waves are going to get smaller in the next couple of days. At the moment I am still in washing machine mode. Time to get back to some faster sailing then. The lines in different colours depict the estimates of different weather models. The most accurate ars the black (ECMWF) and green (GFS) lines. Wave height means the average of the highest 25% of the waves if i recall that number correctly by heart. Individual waves can be (and are) significantly higher.
