Wrocław, the largest city of western Poland, sits on the Oder River on the flat Silesian plain, far from any sea at approximately 51.11°N, 17.04°E. Its inland position gives it a humid continental climate (Köppen Dfb/Cfb) — with warm summers and cold winters — and it is among the warmest and driest of Poland's major cities.

Summer, from June to August, is warm, with July the warmest month — average highs around 25–26°C, the warmest in Poland — and heatwaves that can exceed 35°C on the sheltered Silesian plain. It is the wettest season, with frequent, sometimes heavy thunderstorms, though totals remain modest and the sunshine is generous.

Winter, from December to February, is cold and often grey, with January the coldest month — average highs around 2°C and lows near -3°C, and cold snaps from continental air that can drop below -15°C. Snow falls and can lie for weeks, and the flat plain readily traps fog and winter smog during still, high-pressure spells.

Wrocław is among the driest Polish cities, receiving only around 570–600 mm of precipitation a year, sheltered from Atlantic rain by distance and by the uplands to the southwest, with a clear summer maximum from thunderstorms. Live rainfall, humidity, and pressure readings for the city are shown in the panels above.

Wrocław's sheltered position on the Silesian plain gives it Poland's warmest summers and among its lowest rainfall. Its riverside setting on the Oder, however, has proved dangerous: the catastrophic flood of July 1997 inundated much of the city when torrential rain overwhelmed the river's upper catchment.
