Istanbul heatwave survival guide: Tips to handle record humidity

Istanbul’s heatwave reached a new high with an extremely humid and hot night on June 20-21, with the humidity levels reaching unprecedented highs in several districts.

The city’s early morning hours saw temperatures around 78.3 degrees Fahrenheit (25.7 degrees Celsius) with a perceived heat of 82.9 degrees Fahrenheit, coupled with an average humidity of 83%.

Istanbul districts that see record humidity

According to reports, the humidity levels soared to over 95% in many districts, including Atasehir, Besiktas, Beyoglu, Catalca, Kagithane, Sariyer, Silivri and Sisli. The highest humidity was recorded in Atasehir and Umraniye, both hitting a record of 99%.

In Atasehir, the temperature was measured at 74.7 degrees Fahrenheit with a perceived heat matching the air temperature, but the humidity reached an unbearable 99%. Similarly, Umraniye, with a temperature of 74.5 degrees Fahrenheit, also experienced a record 99% humidity.

These levels are particularly challenging, making the air feel much warmer than the actual temperature. A resident from Atasehir said, “The air feels like it’s suffocating us; it’s almost impossible to breathe.”

Worst districts of Istanbul in terms of heat, humidity

Districts like Besiktas and Beyoglu also reported significant discomfort, with temperatures around 77.7 degrees Fahrenheit and humidity levels of 98%. Beyoglu, in particular, had a perceived temperature of 102.7°F because of the high humidity.

Other districts also experienced high humidity, with Kadikoy at 87%, Kartal at 88% and Sariyer at 95%. These conditions made it difficult for residents to find relief, even during the cooler night hours. One local in Beyoglu mentioned, “It feels like we’re in a steam room, and there’s no escape from it.”

Turkish experts’ advice about heatwaves

Experts attribute these extreme conditions to a combination of high temperatures and humidity, creating a stifling environment.

Meteorologists explain that the combination of high humidity and temperature prevents the body from cooling down through sweating. This can lead to heat-related illnesses, especially among vulnerable populations like the elderly and children.

The Istanbul Metropolitan Municipality’s Disaster Coordination Center (AKOM) issued a warning regarding the high temperatures, emphasizing the risks to vulnerable groups such as the elderly, sick, pregnant women, and children.

They advised:

• Avoiding prolonged exposure to the sun, particularly between 11 a.m. and 4 p.m.
• Stay hydrated
• Seek air-conditioned environments when possible.

Following these guidelines can help ensure safety and health during extreme heat and humidity conditions.
