On May 15, Türkiye is experiencing a weather split between its western and eastern regions. While many western cities prepare for evening showers, the east braces for rain mixed with snow at higher elevations. The Turkish State Meteorological Service (MGM) forecasts that eastern Türkiye will see widespread rainfall throughout the day, some of it intense, while the western regions will turn cloudier and rain-prone by nighttime. Here’s a focused look at the weather in key cities across the country:

Istanbul

Türkiye’s largest city will be partly to mostly cloudy throughout the day. No rainfall is expected during daylight hours, but skies will become increasingly overcast in the evening. Temperatures will remain mild, with a high of around 21°C.

İzmir

İzmir will start the day with partly sunny conditions, gradually becoming cloudier. By nightfall, showers and possible thunderstorms are expected to move in. Daytime highs are forecasted to reach 26°C.

MUĞLA

Although not mentioned explicitly in today’s forecasts, Muğla — like much of the Aegean region — can expect partly to mostly cloudy skies, with a chance of evening rain, especially near the coast. Temperatures will likely peak around 24–25°C.

ANTALYA

The popular Mediterranean city will enjoy partly cloudy skies with no expected rainfall. It’s one of the drier spots in southern Türkiye today, with pleasant conditions and temperatures near 26°C.

Şanlıurfa (Urfa)

Urfa will see cloudy skies throughout the day. Showers and localized thunderstorms are likely, especially in the afternoon. Temperatures will hover around 22–24°C.

Eastern Kars will be heavily clouded, with intermittent rain that may turn to snow or sleet at higher elevations early in the day. Rainfall could become locally strong in the afternoon. Temperatures will stay cool, peaking around 9°C.
