Türkiye is set to experience an unusually warm October weekend, with temperatures climbing to 33 degrees Celsius (91.4 degrees Fahrenheit) in some areas before widespread thunderstorms and cooler weather move in early next week, according to forecasts from the Turkish State Meteorological Service (MGM).

The warm spell, known locally as "pastirma yazi," refers to a brief period of mild, sunny weather during autumn, similar to what is commonly called an "Indian summer" in English.

Clear skies and above-seasonal-feeling warmth are expected across much of the country on Saturday, Oct. 10, with temperatures reaching 25°C in Istanbul and Ankara, approaching 30°C in Izmir and climbing to 33°C in Adana.

Sunny weekend brings summer-like temperatures across Türkiye

The Mediterranean region is expected to enjoy particularly warm conditions, with Antalya reaching 27 °C, while temperatures along parts of the Black Sea coast, including Zonguldak and Bartin, are forecast to range between 28 °C and 30 °C.

Further east, Trabzon and Rize are expected to reach 23°C, while southeastern cities, including Gaziantep, Sanliurfa and Adiyaman, could see temperatures between 25°C and 30°C.

Despite the largely clear conditions, fog and mist may develop in the morning across Marmara, coastal Aegean areas, inland parts of the central and eastern Black Sea regions, and eastern Anatolia.

Thunderstorms expected in southeastern cities on Sunday

Temperatures are expected to remain largely unchanged on Sunday, Oct. 11, although cloud cover will build up across the country.

Istanbul is forecast to reach 24°C, Ankara 25°C, and Izmir 28°C, while Antalya could climb to 30°C and Adana to 32°C.

Thunderstorms are expected around Kayseri, Nigde, Kilis, Gaziantep, Adiyaman, Sanliurfa and Mardin, while most other areas are expected to remain dry.

Rain and falling temperatures to follow from Monday

The warm spell is forecast to give way to widespread thunderstorms beginning Monday, Oct. 12, as a new weather system moves across Türkiye.

Rainfall is expected to affect much of the country through Wednesday, Oct. 14, while temperatures are forecast to begin falling from Tuesday, bringing the brief period of summer-like October weather to an end.
