Istanbul weather reviews

Alina, July 2023
We vacationed in Istanbul with my family in July. The air temperature was +28-32°C, it was quite well tolerated, there was no discomfort. It took literally a day to adapt after the flight. The coast of the Sea of Marmara warms up by an average of +24°C. Sunbathing and swimming are comfortable. Night time is accompanied by a decrease in the thermometer by 5-7 degrees, and shows a value of +23-26°C, and a breeze of 5-6 m/s is remarkably refreshing.
