Late-September warmth holds Central Europe – but France turns much wetter by Wednesday

Late-September warmth remains entrenched across much of Central Europe from Tuesday afternoon into Wednesday. Germany, Switzerland and Austria stay unusually mild to warm, while much of Italy remains stable under high pressure. France is the clear exception, with a more active Atlantic and Mediterranean pattern beginning to take hold.

Tuesday afternoon temperatures range from the upper teens and low 20s near some northern coasts and higher Alpine locations to 26–31 °C across large parts of France, western and southern Germany and other warm lowland areas. Austria reaches 22–28 °C, while many Swiss lowlands are in the mid to upper 20s.

Overnight into Wednesday, temperatures vary widely. Central European valleys can drop into single digits, while western France and Mediterranean districts remain remarkably mild, locally around 18–22 °C. Wednesday daytime highs are broadly 17–29 °C across Germany, Austria, Switzerland, France and much of Italy, depending strongly on elevation and cloud cover.

The main weather change develops over France. An active rain band crosses the north-western half of the country on Wednesday, while the south-east faces a potentially intense and persistent heavy-rain and thunderstorm episode. By contrast, Austria, most of Switzerland, much of Germany and most of Italy remain largely dry through Wednesday evening, although western Switzerland and western Germany see increasing cloud and a higher chance of showers later.
