Weather on the Rostock Trelleborg crossing
Wind, wave height and storms for both ports and the water in between, so you know what the crossing will feel like.
Prices and availability via Direct Ferries
The season
The Baltic is usually calm through the summer. From autumn on it gets considerably rougher, and storm warnings can mean delays or a cancelled sailing.
What matters
Wave height tells you more than wind speed about how the crossing will feel. Anything under a metre is a quiet trip.
Delays
A forecast is not an official notice. Your operator decides whether a sailing runs, so check with them on the day if the weather looks bad.
Live maps for both ports and for the water in between. Wind and wave height are what decide whether the crossing feels calm or rough, and in autumn and winter they occasionally decide whether it sails at all.
Weather at Rostock ferry port
Conditions at the Überseehafen terminal, where you check in and wait.
Weather at Trelleborg ferry port
Conditions at the Swedish end, useful whether you are boarding there or driving on after arrival.
Wind on the crossing
Wind is the single best indicator of how the crossing will feel. The map is centred on the middle of the route, roughly halfway between the two ports.
Wave height on the crossing
If you are prone to seasickness, this is the map to check. The Baltic is usually calm in summer and considerably rougher from autumn onwards.
Temperature on the crossing
It is normally cooler on deck than in either port, because there is nothing to break the wind out there. Worth a look before deciding what to wear.
Rain and storms over the Baltic
Precipitation across the route. Heavy weather systems moving over the Baltic are what lead to storm warnings, and storm warnings are what lead to delays and cancellations.
When the weather actually matters
For most summer crossings it does not. From October through March it is worth a check the day before, especially if you have a connection to make on the other side or you are travelling with a high-sided vehicle such as a motorhome or a caravan, which are the first to be affected by strong crosswinds on the vehicle deck.
If a storm warning is in force, check directly with your operator before driving to the port. A cancelled sailing is easier to handle from home than from a queue at the terminal.

Frequently asked questions
Can weather cancel the Rostock Trelleborg ferry?
It can, though it is uncommon. Storm warnings on the Baltic occasionally cause delays or cancelled sailings, mostly in autumn and winter.
Which forecast should I check?
Wind and wave height. Those two determine how the crossing feels far more than temperature or rain do.
Is the Baltic crossing rough?
Usually not in summer. Autumn and winter can be noticeably rougher, and the ships are large enough that moderate swell is barely noticeable.
Should I check both ports as well as the crossing?
Yes, if you have a long drive on either side. Conditions at the terminal and out at sea are often different.
Does bad weather make the crossing longer?
It can. Strong headwinds or heavy swell add time to the usual 6 hours, so leave margin if you have something to catch after arrival.
