True if there is a substantial depression over the Atlantic.
The more you’ll approach the sea, the less likely it is to be the case, in particular in August.
Upon entering Britanny, you can expect a so-called “ Coastal effect” generating a Thermic Breeze” , with headwinds during the day, since temperatures climb faster inland than over the sea and the opposite at night time since its the sea which cools down faster.
There’s a narrow window, in summer, when Inshore temp = offshore temp with no wind at all, twice a day.
As the crow fly, Paris isn’t that far from the coast, depending upon weather systems, that’s, IMHO, worth considering.
Indulge in a nap in the afternoon instead of fighting a headwind and ride at night, instead.
