The waters in the Norwegian fjords are generally much calmer than the open sea, thanks to the fjords' narrow and sheltered characteristics. This makes Norwegian fjord cruises an excellent choice for those who may be concerned about sea sickness.
The fjords' tall mountains provide protection from the wind and sea conditions, resulting in smoother sailing experiences. However, when travelling to and from the fjords, it's possible to encounter rougher seas, especially in the North Sea, depending on the weather and the season.
Most modern cruise ships are well-equipped with stabilisers to minimise the motion felt on board, ensuring a comfortable journey for passengers.
