Summer in France is a time for holidays for the French (and many foreign tourists) with the French going to one of its many beach resorts (three quarters of the country is coastline). Popular spots include Ile de Re and the Riviera. There is also a fake beach set up in Paris on the banks of the Seine during August. Other waterside spots (lakes, rivers) are also popular.
In August, the French traditionally take their holidays. So you may find some shops closed for the first half of August. Northern France tends to migrate south from mid July and Bastille Day to mid-August. See statistics about the French and their summer holidays
