These temperatures will be well above seasonal normals.

This change is explained by a shift in the source of the air masses influencing the country. This change is due to a shift in the origin of the air masses influencing the country. France will see a gradual shift from a traditionally cool northerly flow to a much warmer southerly one.

The impact of this southerly flow will vary from region to region. In the south-west, it will favor a Foehn effect, a phenomenon that makes the air drier after the passage of a mountain range, leading to a natural rise in temperatures. Temperatures in excess of 20°C are expected in these areas on Friday afternoon.

In short, this week in Paris and Île-de-France will be marked by a notable transition to milder, above-seasonal temperatures, mainly due to a change in atmospheric circulation bringing warmer air from the south. It's the perfect opportunity to take a stroll in Paris and enjoy the mild winter weather.
