Latest Status of Şehir Hatları and BUDO Services
Şehir Hatları, operated by the İstanbul Metropolitan Municipality, has announced that it has not made a new general service cancellation decision for November 5, 2026. Passengers traveling on routes such as Kadıköy, Üsküdar, Beşiktaş, Eminönü, Karaköy, and the Princes' Islands (Adalar), should monitor the official Şehir Hatları announcement page for current departure times in case of possible delays or changes in pier calls.
No new service cancellations have been reported by Bursa Sea Buses (BUDO) for November 5, 2026, either. BUDO services between Mudanya and İstanbul's Eminönü/Sirkeci are continuing as per the current schedule. However, wind and wave conditions in the Sea of Marmara may cause instant changes to service times throughout the day. Passengers traveling from Bursa to İstanbul or from İstanbul to Mudanya are advised to check BUDO's live service inquiry screen.
Impact of Weather Conditions on Sea Transport and Passenger Guidance
Adverse weather conditions in the Sea of Marmara can affect long-distance sea bus services in particular, leading to changes in travel plans. While city ferry lines and open-sea sea bus services may be affected differently by the same weather conditions. Therefore, a service cancellation by one operator on a specific route does not mean that all services by other operators are also suspended.
It is crucial for passengers using sea transport to check current service information on the official websites of the respective operators:
