Istanbul is bracing for the hottest stretch of the year, with temperatures expected to climb from around 33°C (91.4°F) to nearly 35°C (95°F) between Wednesday and Friday as cooling winds die down.

According to the latest assessment by the Turkish State Meteorological Service, no significant change in temperatures is expected on Tuesday.

However, hotter and more humid conditions are set to build up across the city from Wednesday, Aug. 5, through Friday, Aug. 7.

Cooling winds begin to fade

Istanbul has experienced a relatively milder summer compared with previous years, partly because of the poyraz, a dry northeasterly wind that commonly blows across the Marmara region.

The wind has made temperatures feel cooler than their measured levels, but its influence is expected to weaken, allowing the heat to intensify later in the week.

Humidity set to make heat feel heavier

NTV Meteorology Editor Dilek Caliskan said the hot weather pattern would remain in place until Aug. 13.

Temperatures in Istanbul are expected to reach around 33°C on Wednesday before moving toward 35°C by Friday. Relative humidity could also climb to between 90% and 95%, adding to the uncomfortable conditions.

Dry winds keep wildfire risk in focus

Caliskan also pointed to a continued forest fire threat along the Canakkale-Manisa corridor, where the poyraz is blowing strongly and carrying little moisture.

"This week, because it is blowing very strongly, there is a forest fire risk in these areas," she said.

The wildfire threat is also expected to continue across inland parts of Izmir this week, while the risk around Antalya has declined.
