Humid night warning for Istanbul: Humidity could reach 91 percent between 03:00 and 06:00

Stifling weather is expected to intensify in Istanbul tonight. According to forecasts, the humidity level across the city could rise to 91 percent between 03:00 and 06:00.

While the heatwave coming from Africa and Basra continues to affect most of the country, the weakening of strong winds is causing the humidity to be felt more intensely. For this reason, it is stated that a suffocating environment may occur, especially during the night hours, regardless of the air temperature.
