Overview
- Monday opens with stark regional contrasts: sunshine and mild air in the south, lingering clouds with fading rain in the north, and persistent humidity and wind along Manche and Brittany coasts.
- Morning readings set the tone in the north with unusually high values — around 15°C in Paris and Nantes and 14°C in Le Havre — sitting roughly 8 to 12 degrees above seasonal norms.
- Afternoon highs reach about 14°C in the north and up to 17°C in the south on Monday, then climb further Tuesday with 14–20°C nationwide and peaks near 20°C around Biarritz.
- Forecasters flag frequent morning fog from Aquitaine to the Centre-East, gusts up to roughly 50 km/h in the Paris basin Monday, and rain confined mainly to Brittany on Tuesday.
- The mild pattern is expected to persist through the week with a disturbance crossing southwest to the Ardennes on Wednesday, brighter spells Thursday, renewed showers in the northwest Friday, and a cloudier weekend, as accelerated snowmelt affects the Vosges, Jura and Massif Central with the freezing level near 3,200–3,300 m.
