Severe Weather in Poland
Poland sits where maritime and continental air masses collide, giving it a full menu of severe weather: summer tornadoes, violent derechos, giant hail, and some of Europe's worst river floods. Here is the overview.

Poland's severe-weather profile
Poland lies in a transition zone where warm, humid air drawn up from the Mediterranean and the continent meets cooler Atlantic and polar air. In summer this fuels powerful multicell and supercell thunderstorms across the central lowlands, capable of large hail, damaging straight-line winds, and tornadoes. In spring and summer, snowmelt and torrential rain over the Sudetes and Carpathians feed the Oder (Odra) and Vistula (Wisła) rivers, producing catastrophic floods.
The main hazards
- Tornadoes (trąby powietrzne) — a handful of significant ones each year, mostly July and August. See tornadoes in Poland.
- Derechos and windstorms — long-lived, fast-moving thunderstorm complexes that flatten forests, like the devastating August 2017 derecho.
- Large hail — supercells over southern and central Poland regularly drop hail several centimetres across.
- River flooding — the Oder and Vistula basins have produced some of Europe's deadliest modern floods. See Poland floods.
- Winter storms — Baltic gales, heavy snow, and freezing rain.
Where to get official warnings
The national authority is IMGW-PIB, which issues colour-coded warnings for storms, wind, rain, and flooding. Poland's alerts also feed the pan-European Meteoalarm aggregator, and forecasters watch the daily ESTOFEX storm forecast for severe-weather risk across the continent.
