Yes, ferries are frequently cancelled, and in 2026, the primary reason remains adverse weather conditions, particularly high winds and heavy seas. Safety regulations (such as those from the IMO) prevent vessels from operating when wave heights exceed the ship's "significant wave height" rating. In addition to weather, ferries can be cancelled due to technical mechanical failures, labor strikes, or tidal restrictions in certain shallow-water ports. During the 2025/2026 winter season, many English Channel and Mediterranean routes saw increased cancellations due to unseasonably strong "storm cycles." If your ferry is cancelled, operators are generally required to offer you a choice between a full refund or re-routing on the next available sailing. It is highly recommended to sign up for SMS alerts from the ferry company, as cancellations can happen with very little notice, sometimes while passengers are already waiting at the terminal.
