July-August is peak season, it is when French families take their holidays and crowd sites and beaches. If you are driving, be prepared for heavy traffic on the approaches to major conglomerations such as Caen and for queues of traffic for popular sites, particularly at weekends.

You should be aware of the holidays dates in France to plan your trip ahead. At http://www.bison-fute.equipement.gouv... you will find not only a calendar of holidays but also information about climate and traffic conditions in most important highways (routes and auto routes), safety recommendations, and traffic and transportation regulations.

It is wise to check opening times of sites and museums that you are planning to visit because many close for lunch and have different opening days or hours according to the season.
