Pictures of some principal French attractions
March – early October for sightseeing; June – September for beaches tho’ July and August are overheated/overcrowded on the Côte d’Azur; January-March for winter sports.
Beware July and August when the country is packed with foreign and local tourists. Avoid driving on the weekend at the beginning of August, it’s hell on wheels, bumper-to-bumper even on autoroutes. Some services in Paris – even museums and restaurants – are closed.
Atlantic beaches are warm and useable though the waters never warm up to Mediterranean standards.
November-February can be bitterly cold in mountain areas and in the north including Paris, though the Cote d’Azur may well see blue skies and daytime T-shirt weather, but. . . rain is equally likely in winter.
