After the cold and the gray, the rain and the wind. The weather models seem to be converging towards a change in weather at the end of the week, and probably (at least) a strong gale from this Friday, January 24, 2025 in the west of France, in Brittany and Normandy in particular.
And the weekend of Saturday January 25 and Sunday January 26, 2025 is not much quieter. Few regions will escape precipitation.
A particularly deep depression on the British Isles
Wind gusts over 100 km/h are envisaged on the coast, “in connection with the passage of a particularly deep depression over the British Isles”, anticipates actu.fr meteorologist Yann Amice.
This depression, northwest of the Azores this Thursday, January 23 at 1,000 hectopascals, is expected to deepen very violently at 946 hpa Friday, January 24 and sweep the west of France. An explosive cyclogenesis since we will lose more than 33 hPa in 24 hours!
The wind could prove violent, on the threshold of the storm on the Channel coasts, and cumulative rain could also be significant in the north-western quarter of the country from this Friday, January 24. All with a lot of swell.

In connection with the cold snap in the United States…
This radical weather change actually originates in the United States, which is experiencing an impressive cold snap and a succession of polar air drops.
While for several days the meteorological situation in France had been blocked with a powerful anticyclone on the European continentthis context in the United States “will revitalize the jet stream (or jet-stream in English) a very powerful upper-altitude wind axis across the entire Atlantic, causing depressions to run aground over Europe,” continues Yann Amice.
If this first depression positions itself over Ireland on Friday, Saturday January 25 and Sunday January 26, it will be necessary to carefully monitor another system near the Azores which could well come to circulate near the coasts of Brittany and bring still very strong winds.
Temperatures will rise
The calm and very wintery weather is over, so, from the end of the week, with temperatures which will rise, but also very disturbed weather conditions to be expectedtherefore with a lot of rain and wind (from the southwest sector).
And with the return of this disturbed westerly current, the rainy and windy waves will parade across Western Europe, probably for several days.
Rain: 2024, a near-record year
With more than 1,000 millimeters on average over France (1,075 mm), the year 2024 ranked among the ten rainiest years since 1959.
In Châteaudun (Eure-et-Loir), Blois (Loir-et-Cher) as in Paris, 2024 was even the second rainiest year ever observed. In Saint-Nazaire (Loire-Atlantique), the year 2024 was the wettest with more than 1,100 mm since 1957, recalls Météo France.
The sun was particularly absent in February, May, September and October, especially in the northern half. 2024 was on average the least sunny year that France has experienced in almost 30 years. And 2025 is currently not much brighter in the north of France…
