Europe Split in Two: 38°C Heat in the Southeast, Heavy Rain in the North
The week of 17–23 August 2026 splits Europe into two very different weather regimes. Cooler, wetter Atlantic air dominates much of western and northern Europe, while southeastern Europe turns hotter and increasingly dry. Central Europe sits between the two, with sharp temperature swings and several heavy-rain episodes.
Europe weather 17–23 August: key points
Cooler and wetter: the UK, Ireland, Benelux, Scandinavia and parts of Central Europe.
Heavy rain signals: Amsterdam, Zurich, Prague, Warsaw, Vilnius and Rome.
Strong late-week heat: the Balkans, Romania, Moldova, Ukraine, southern Russia, Greece and Turkey.
Hottest cities: Athens +37.9°C, Belgrade +37.6°C, Sofia +36.6°C, Madrid and Rome +36.0°C.
Kyiv: a dramatic swing from around +31°C to +24°C and back toward +34°C.
Western and Northwestern Europe turn cooler and wetter
Atlantic systems push east after 17–18 August, bringing lower daytime temperatures, more cloud and more frequent rain. Glasgow stays cool at around +16…+18°C. Dublin ranges from +16 to +23°C and cools after Monday, with rain around 20 August. London peaks near +26.2°C before turning cooler and mostly dry.
Paris reaches about +28.8°C before a sharp cooldown, with roughly 14 mm of rain possible on 19 August. Amsterdam stands out for a very wet week, with local daily totals near 20 mm.
Rain focus: this is a wetter Atlantic-driven pattern, but the supplied forecast does not confirm flooding. The strongest wording supported by the data is heavy or very heavy rain in selected locations.
Central Europe becomes the main transition zone
Central Europe lies between cooler Atlantic air and much hotter air over southeastern Europe. Berlin starts cool, then turns drier and slightly warmer. Zurich reaches nearly +29.6°C, but its standout feature is very heavy rain around 20 August, with about 35 mm possible.
Prague stays changeable, with heavy rain possible around 21 August. Vienna rebounds toward +32.8°C before wetter weather on 21–22 August. Bratislava sees hot intervals followed by a wetter, potentially stormier late-week pattern. Budapest becomes one of the hottest Central European capitals at about +35.1°C and remains mostly dry.
Why Central Europe is so changeable: it sits close to the boundary between cooler Atlantic air and much warmer air farther southeast. Small shifts in that boundary can quickly change temperature and rainfall from one day to the next.
Poland, the Baltics and Scandinavia stay on the wetter side
Warsaw has several days with substantial rain. Vilnius could receive around 25 mm on 18 August. Riga sees frequent showers, while Tallinn remains cool and becomes increasingly wet.
Stockholm stays mild, then becomes wetter toward the weekend. Oslo has rain signals on 17 and 22 August. Helsinki remains cool and turns wetter by 21–23 August.
Eastern Europe heats up again late in the week
Minsk reaches around +25.2°C but has a heavy-rain signal around 18 August. Moscow warms later, reaching about +26.9°C, with rain risk around 22 August. Voronezh has a sharp cool dip on 19 August before heating back up to around +33.6°C.
Ukraine: a sharp dip, then heat returns
Kyiv is one of the clearest examples of the week’s volatility. The temperature sequence is roughly +31°C → +24°C → +34°C, with a weekly peak near +34.1°C. The supplied forecast keeps Kyiv mostly dry.
Simferopol also cools sharply around 19 August before warming strongly again, with a later peak around +33.8°C.
Late-week hot zone: the strongest heat builds from Ukraine and Moldova through Romania and the Balkans toward Greece and Turkey, with several locations reaching +34…+38°C.
Moldova, Romania and the Balkans become hot and mostly dry
Chișinău reaches around +34.4°C under a predominantly dry pattern. Bucharest remains persistently hot at around +31…+35°C, peaking near +34.9°C.
Belgrade becomes one of Europe’s hottest major cities late in the week at about +37.6°C. Sofia follows with a peak near +36.6°C, mainly under dry conditions.
Spain cools after early heat; Rome mixes heat with heavy rain
Lisbon stays dry and reaches about +31.8°C, with the hottest weather early in the week. Madrid reaches +36.0°C on 17–18 August before noticeably cooling.
Rome also peaks around +36.0°C, but a very heavy rain episode is possible around 21 August, with roughly 28 mm in the daily signal.
Greece and Turkey remain firmly in the heat
Athens is the hottest city in the supplied set, with a weekly range near +32…+38°C and a peak of +37.9°C. The forecast signal is completely dry. Ankara warms steadily and reaches about +34.6°C.

What to watch through the weekend
The central story is the growing contrast across Europe. Cooler Atlantic air dominates the northwest, while much hotter air expands across the southeast. Central Europe remains the main battleground between the two air masses, with the highest risk of abrupt temperature changes and locally heavy rain.
By the weekend, the strongest heat is concentrated across the Balkans, Greece and parts of eastern Europe, while wetter weather remains more likely from Central Europe northward into the Baltic and Scandinavian sectors.
