It all depends on why you're going to France. The ski season runs from November to April, but weather conditions vary from year to year and from ski resort to ski resort. The summer holidays are the height of the tourist season. July and August are also the hottest months, so if you'd prefer to avoid searing heat – especially in southern France – and higher prices, head to France in June or September. The cultural vibrancy and nightlife of French cities continue all year round.
