From mid-day and afternoon, the sky alternating with brief clearings, numerous and imposing cumulus clouds generating a few showers. Sustained southwest wind in the morning (strength 4, gusts 40-50 km/h, 50-60 over Groix) weakening slightly in the afternoon (strength 3-4, gusts 35-45 km/h, 45-55 on Groix and the exposed coastline).

Sunday
The front which continues to skirt Brittany will generate an overcast and grey sky in the morning with sustained and continuous rains becoming progressively moderate and continuous. In the afternoon, despite the strengthening of the high pressure, the front, more attenuated, continues to skirt Brittany, generating an overcast and grey sky with light rain. Strong southwest wind at the start of the morning (strength 5-6, gusts 70-80 km/h, 85-95 over Groix and the exposed coastline) weakening (strength 4-5, gusts 55-65 km/h, 65 -75 on the coastal fringe).

On Monday
The front which continues to undulate on the Channel will descend gradually towards Brittany, pushed by the high pressure and the descent of moderate cold air which accompanies it. Overcast, grey and very soft in the morning and mid-day with rare light rain. In the afternoon, the front that descends from Aber Wrac’h will generate an overcast sky with moderate and continuous rain until early evening. Strong south-westerly wind in the morning and mid-day (strength 5, gusts 55-65 km / h, 65-75 on the coast) veering, west to northwest weak on the continent and moderate on the coast.

Wednesday focused in the heart of the high, Brittany will experience a beautiful bright day despite the presence of very high altitude sails. Weak east to southeast wind. Mini: 1 / 2 degrees; max: 7 / 8 degrees (Feeling oscillating from 0 to + 6 degrees).
On Thursday, the vast high-pressure conditions continue to push the rains over Ireland generating a bright day. Weak to moderate wind from southeast to east; Mini: 0 / 1 degrees; max: 6 / 7 degrees, felt from -2 to + 4 degrees.
Persistent oceanic softness
Driven by an imposing disturbed ocean current, winter has still not set in despite some vagaries. If south of the 55th north parallel, fresh air masses continue to circulate (+ 5 ° / + 10 ° at 1,500 m altitude), you must go north of the 65th north to find masses of air colder and which does not descend under the effect of an ocean current of low layers and very high altitude. Near 12.5 to 13.5 degrees in southern Brittany this Thursday, the temperatures reached 10 to 12.5 degrees in Ireland as astonishing 9 to 11 degrees in the Netherlands and 8 to 11 degrees in Scotland. Further east, the mercury oscillates from 8 ° to 3 ° from the west of Germany to the east of Belarus. Close to 0 ° / 1 ° in Moscow, you have to reach central Russia or Siberia to observe negative values.
