In mid-July 2026, the Meteorology General Directorate issued warnings for extreme weather across Turkey, including high temperatures in southeastern Anatolia and heavy rainfall along the eastern Black Sea coast. By mid-August, patterns shifted toward heavy rain and thunderstorms in the central and eastern Black Sea coasts, while southern regions like Antalya and Diyarbakır remained hot.

On August 11 and 12, 2026, meteorological authorities and the Istanbul Governor's Office issued widespread warnings for severe conditions. In the Marmara and North Aegean regions, including Istanbul, Izmir, and Çanakkale, wind speeds were expected to reach between 60 and 80 km/h, creating risks of falling trees, flying roofs, and transportation disruptions. Due to high wave heights and dangerous currents, local authorities implemented temporary swimming bans at numerous coastal locations, including beaches in Bartın, Trabzon, Sakarya, Zonguldak, Tekirdağ, and several Istanbul districts such as Şile, Arnavutköy, Beykoz, and Sarıyer.

Simultaneously, heavy rainfall and thunderstorm warnings were issued for the Black Sea region, specifically Samsun, Ordu, Sinop, Giresun, Rize, and Artvin. In Giresun, heavy rains have caused rivers to overflow and landslides, impacting local roads and damaging infrastructure, including a hydroelectric plant in the Yağlıdere district.

By August 14, swimming bans expanded across multiple provinces due to ongoing adverse weather, including strong winds and high waves. In Bartın, 11 beaches including İnkumu and Güzelcehisar were closed through August 16. In Tekirdağ, prohibitions were implemented in Marmaraereğlisi, Şarköy, Süleymanpaşa, Çorlu, and Saray. Along the Black Sea, bans extended to Trabzon, Giresun, and Kocaeli’s Kandıra district, while Kastamonu saw closures in Abana and Cide. In Kırklareli, beaches in Vize and Demirköy, specifically Kıyıköy and İğneada, were also closed.
