Do not underestimate the Baltic Sea if you slightly worry about the west side of Denmark at first!
The layout of the waves is not as high as on the west side, but more kind of sqare and they follow closer together.
It seams to be calmer...but especially with a nice wind from the east side over 2-3 day´s, not calm any more, and they hit you from port side if you circumnavigate clockwise.
Could be more destroying for physicals and material.
If, i would plan that for july or august, not that cold not that windy......mostly!!!
