Highs of 26C expected as summer makes brief return to Germany

By Olivia Logan

After a spate of autumnal weather, sunshine and highs of 26 degrees celsius will return to much of northern Germany from Tuesday to Thursday, September 19.

Sunshine and warm weather forecast for northern Germany

After being plunged into autumn weather, summer will make a brief reprise in northern and central Germany this week, according to the German Weather Service (DWD).

On Tuesday afternoon, cities north of Frankfurt will begin to feel the sunshine. Highs of 22 degrees are forecast for Frankfurt, Cologne, Dresden, Bremen, Hanover and Hamburg. Meanwhile, locals in Leipzig can enjoy 23-degree warmth and 25 degrees in Berlin.

Along the Baltic Sea coastline in Rostock, a moderate 20 degrees will prevail and in the south, intermittent sunshine and highs of just 17 degrees are expected in much of Baden-Württemberg and Bavaria.

On Wednesday, temperatures will rise slightly across the country; with 26 degrees forecast for Berlin, 25 for Cologne, 24 for Hamburg and Frankfurt, 23 for Nuremberg and 19 degrees for Munich.

The sunshine will wind down towards the end of the week but highs of 24 in Cologne and 23 degrees in Berlin and Bremen will persist into Thursday.

After the Global North recorded its hottest summer ever in 2024, autumn began with more record-breaking temperatures and a heat warning in eastern Germany. Speaking to rbb, meteorologist Ingo Bertram assessed the early September weather as “around 10 degrees celsius warmer than normal”. 

Storm Boris hits Germany and neighbouring countries

While sunshine is expected, Germany remains cautious, preparing for possible flooding and disruption as Storm Boris batters neighbouring Austria, Poland and Czechia.

The German State Flood Centre announced on Monday morning that water levels in the River Elbe sat at 5,54 metres, triggering stage two of a four-stage warning system. It is expected that stage three will be triggered on Monday when 6 metres is reached.

Before water levels rise further, workers in the capital of Saxony are rushing to clear debris from the 100-metre Carola Bridge, which unexpectedly collapsed into the Elbe last week.

In Bavaria, experts are also cautious of water rising in the Danube, Vils and Isar rivers as the DWD expects more rain to run down from the Alps.
