For a good impression of the weather conditions during the Puttgarden-Rødby crossing, you can refer to the maps below. These maps provide information on wind direction, wind speed, wave height, wave direction, and precipitation.
Any precipitation is represented by colored clouds. The direction of the wind is also indicated so you can make an estimation of what is coming your way.
Will it be a smooth crossing or not? The height of the waves is an important indicator of the comfort level during the crossing. If the map turns red instead of green, you can expect a fairly rough sea.
