Turkey is facing a new heatwave during this first week of August, with temperatures set to exceed the usual levels for this time of year across much of the country. Thermometers are forecast to exceed 40 ºC in some regions, whilst the high humidity will make conditions particularly stifling in Istanbul and other coastal areas of the Marmara region.
According to the latest forecasts from the General Directorate of Meteorology, no significant changes in air temperatures are expected, and figures over the coming days will remain close to seasonal levels, although they will be above average in southern and eastern Anatolia.
Meteorologists warn that the highest temperature will be recorded in the south-eastern province of Şanlıurfa, where it will reach 43 ºC, reported the Turkish newspaper Dünya. Also noteworthy are the 42 ºC that thermometers are forecast to reach in Diyarbakır and the 41 ºC in Siirt. Temperatures are also expected to reach 39 ºC in Malatya and Denizli, 38 ºC in Mardin and 37 ºC in İzmir, Manisa and Muğla.
The summer heat will also affect major cities in Türkiye. Temperatures are forecast to reach 32 ºC in Istanbul, 34 ºC in Ankara, 34 ºC in Bursa, 33 ºC in Antalya and 35 ºC in Adana. However, localised rain and thunderstorms are also expected in the areas surrounding the northern provinces of Rize, Artvin and Ardahan, on Turkey’s Black Sea coast, as well as in the inland areas of Sinop, Samsun, Giresun and Trabzon and in the Taurus Mountains region.
In areas of Istanbul, temperatures will approach 40 ºC
Adil Tek, a Turkish meteorologist, told the newspaper Hürriyet that “August will, on the whole, be warmer than June and July. Compared with statistics from the last 30 years, temperatures are expected to exceed seasonal averages across the country”.
“Temperatures in Istanbul have already risen to 30 °C or higher, and according to the forecast for the week, the city’s average temperature will be around 31–34 °C. However, due to the urban heat island effect, there will be significant differences between different areas. Along the Bosphorus, it will feel cooler, at around 27–28 ºC, due to the influence of northerly winds and sea breezes; in areas such as Mecidiyeköy, Fatih and Kadıköy, where there is little wind and a high density of tarmac and buildings, temperatures are expected to approach 40 ºC”, he warned.
Tek emphasised, however, that temperatures in Turkey are not reaching the historic highs of 2025: “Last year, a record temperature of 50.1 ºC was recorded in Şırnak, the highest in Turkey’s history, and we suffered prolonged and intense heatwaves. This year, however, temperatures have not yet reached those extreme levels. Thanks to the ‘Omega block’ system, which is affecting Europe and trapping hot air there, Turkey lies to the east of this system; this situation has allowed polar air from the north to reach our country, preventing temperatures from rising excessively, particularly in the western regions,” he concluded.
