This is quite normal for the winter. Deauville,Cherbourg,Dinard ATC's are all closed on a Sunday morning, customs are normally in attendance(not Cherbourg) If you cant speak french, dont go as they monitor frequencies and give a bollicking to those who dont.
The local flying club is usually active and of course they speak French on RT so it is difficult to ascertain runway in use etc.. also if you land you must close your flight plan by phone to Brest ATCC

Come to Jersey instead or try Le Touquet
