Europe splits in two: late-summer heat from France to the Alps as Atlantic rain and gales gather in the west

Monday afternoon, 28 September, is unusually warm across large parts of continental Europe. Germany reaches the upper 20s and locally around 30 °C in the southwest, Switzerland and Austria sit mostly in the mid-20s, and Italy remains widely in the mid to upper 20s. France is also very warm inland, but the west is already more unsettled.

The British Isles are the clearest sign of the Atlantic change. The Met Office expects a mainly fine Monday for many areas, but rain moves into southeast England overnight and can turn heavy for a time.

Tuesday: warmth remains dominant over the continent

On Tuesday, 29 September, central Europe stays mild to very warm. Western and southwestern Germany reaches roughly 27 to 29 °C, Austria around 20 to 27 °C, and Switzerland broadly 23 to 27 °C in the lowlands. Major Italian cities remain around 26 to 28 °C.

France stays exceptionally warm for the time of year, with 24 to 30 °C over most of the country, while the Channel coast remains closer to 22 to 25 °C. In Poland, temperatures are much more moderate, with Warsaw near 21 °C.

🌍 Europe at a glance

• Central Europe: mostly dry and warm; many lowlands reach roughly 23-29 °C on Tuesday.
• France: 24-30 °C across most areas, but showers and thunderstorms affect parts of the west and south.
• United Kingdom: drizzle early Tuesday, then increasingly windy; gales in the northwest and heavy rain arriving from the west later.
• Italy: widespread late-summer warmth, but local thunderstorm risk increases in parts of Sicily on Tuesday afternoon.

United Kingdom: the Atlantic front arrives

Tuesday begins cloudy in many areas with outbreaks of drizzle. The Met Office expects winds to strengthen through the day, with gales possible in northwestern parts of the UK. Heavier rain then pushes into western regions later, while eastern England can still turn rather warm after a dull start.

Central Europe stays on the calmer side

Switzerland, Austria and much of southern and eastern Germany remain under a much quieter regime. Local morning fog is possible in valleys and low-lying areas, but sunshine dominates after it clears. Nights are noticeably cooler than afternoons, especially in Alpine valleys and southeastern Germany.

France becomes the transition zone

France combines exceptional late-September warmth with increasing instability. Showers and thunderstorms affect parts of the west and southwest, while Mediterranean inflow brings rain toward Languedoc and later the Cévennes. By Tuesday evening, the next Atlantic disturbance is already approaching Brittany.

Across Europe, the key message is not a single continent-wide weather type but a growing contrast: summerlike warmth inland, cooler marine air near some coasts, and a more active Atlantic pattern taking shape from the west.
