Dense Fog Disrupts Maritime Traffic in the Bosphorus Strait
Fog, which began to affect Istanbul, particularly along the Bosphorus line, from the night hours, intensified in the morning. This situation led to disruptions in maritime traffic, negatively impacting both international vessel passages and urban sea transportation. According to information announced by DHA at 08:28 AM on Monday, August 3, 2026, the fog layer was clearly observed from critical points such as Beşiktaş and Ortaköy, while even the 15 July Martyrs Bridge virtually disappeared due to the dense fog.
Canceled Şehir Hatları Services and Announcement Details
To ensure maritime safety as visibility decreased, Şehir Hatları decided to cancel some of its services. A statement on the company's official website read, "Due to unfavorable weather conditions (fog), the services listed below will not be operated until further notice." This announcement affects passengers planning to travel on busy routes such as Beşiktaş - Kadıköy, Kadıköy - Beşiktaş, and Eminönü - Kadıköy. The cancellation details specified in the announcement are as follows:
- Announcement Date and Time: Monday, August 3, 2026, 08:28 AM
- Affected Services: Due to dense fog, some Şehir Hatları services have been canceled until further notice. Specific routes were not listed in the announcement.

Important Information and Alternatives for Passengers
Passengers facing service cancellations due to fog should be aware of several points to avoid inconvenience. Firstly, those with travel plans should check Şehir Hatları's official website, social media accounts, or mobile application before departing. The most current and accurate information regarding canceled services can be obtained from these channels. Alternatively, road transportation options can be considered. Given Istanbul's heavy traffic, departing early or opting for rail systems like the metro/Metrobus can help prevent time loss.
Fog and Maritime Safety in the Bosphorus Strait
The Bosphorus Strait is one of the world's busiest waterways, hosting heavy vessel traffic. Adverse weather conditions like fog pose significant risks to maritime safety in this sensitive region. As reduced visibility increases the risk of vessel collisions, authorities take measures such as closing the Bosphorus to transit passages. Such closures become mandatory to ensure the safety of international maritime traffic and prevent potential accidents during urban ferry services. Bosphorus tours departing from Kadıköy Pier or other piers may also be affected in such situations.
