Canceled Services and Details for October 27, 2026
Şehir Hatları Service Cancellations
Following the General Directorate of Meteorology's storm and heavy rainfall warnings for the Marmara Region, Şehir Hatları decided to cancel some ferry services on Tuesday, October 27, 2026. Services were halted on many routes, particularly the Princes' Islands lines, which provide access to popular destinations like Büyükada, in order to ensure passenger safety. Other Princes' Islands connections, such as Bostancı - Princes' Islands and Kadıköy - Princes' Islands, were also affected.
İDO Service Cancellations
Istanbul Sea Buses (İDO) announced the cancellation of 4 scheduled services on Tuesday, October 27, 2026, due to adverse weather conditions. Passengers planning to travel with İDO are strongly advised to check İDO's official website or mobile application before their journey to avoid inconvenience.
BUDO Service Cancellations
Bursa Sea Buses (BUDO) also canceled 5 scheduled services for Tuesday, October 27, 2026, due to severe weather conditions in the Marmara Region. These cancellations directly affected passengers planning to travel by sea between Istanbul, Bursa, and Armutlu, particularly on routes like Mudanya - Kabataş. Up-to-date information can be found on BUDO's official website.
Adverse Weather Conditions Impacted Sea Transportation in Marmara
According to the General Directorate of Meteorology's forecasts, strong torrential and thundery showers affected the Marmara Region. Winds blowing from the north at speeds reaching 50 to 70 kilometers per hour in the form of strong, short-lived storms negatively impacted sea transportation. Wave heights in the Sea of Marmara were expected to reach up to 3.5 meters in places, which was the main reason for the service cancellations. Such weather conditions pose a risk to maritime safety, leading operators to make cancellation decisions.
