Heavy rainfall to sweep across Türkiye starting April 23

Widespread rainfall is set to impact all regions of Türkiye starting April 23, 2025, according to the Turkish State Meteorological Service under the Ministry of Environment, Urbanization, and Climate Change.

Weather Forecast Expert Cengiz Celik spoke to Anadolu Agency (AA) about the incoming weather pattern and warned of persistent thunderstorms lasting several days across the country.

Local showers to give way to widespread storms

Celik noted that isolated rain is expected in northeastern Türkiye on Monday and Tuesday, with a brief spell of rain also forecasted for the Aegean region on Tuesday evening.

However, the situation will change dramatically from midweek. "Starting Wednesday (April 23), heavy showers and thunderstorms will affect the entire country for four to five days," said Celik.

He added that rainfall will be intermittent but significant in intensity.

Persistent rain in east, strong storms in west

The northeastern regions of Türkiye are expected to experience uninterrupted rainfall throughout the week. Celik stated that the interior parts of the Eastern Black Sea region and the broader Eastern Anatolia region will remain under rainy conditions for at least seven days.

Western parts of the country will start receiving rainfall from Wednesday. Strong thunderstorms are forecasted for the northern and interior parts of western Türkiye on April 23, April 24, and April 25.

Despite the rainfall, Celik emphasized temperatures will remain unchanged, staying above seasonal averages.
