Temperatures over the weekend will be above seasonal averages across most of the country due to the hot weather coming in from North Africa, weather experts warned Monday.

The country's state-run meteorology agency announced that temperatures will be 6-10 degrees Celsius (11-18 degrees Fahrenheit) higher than seasonal averages starting Thursday and the heat wave is expected to last a week.

Temperatures in Turkey’s most populous city, Istanbul, are expected to exceed 30 degrees C, with much of the week expected to be partially cloudy. In the capital Ankara, temperatures will also reach 30 degrees C but cloudy weather is forecast for much of the week.

The Aegean province of İzmir will see temperatures as high as 35 degrees C, according to the agency. The country’s northern Black Sea region will see rainfall for two days before the heat wave arrives.

With many citizens expected to spend their days outside to cool off during the heat wave, experts warned of the lingering coronavirus danger. Despite a common belief that increasing temperatures will affect the virus’ infection rates, experts say there is no scientific data to back such claims.

Last year, Turkey and Europe sweltered under record temperatures. Several provinces across the country saw thermometers exceed 40 degrees C. According to the Turkish State Meteorological Service, Istanbul sweated through its hottest May in 69 years last year, with temperatures exceeding 35 degrees C in some parts of the city.
