Normandy: When to Go
Normandy is at its best between April and October. The summer months are busy with village festivals, fairs and horse racing, and some beaches fill with Parisians in August. Hotspots such as Honfleur can get very crowded, but inland regions such as La Perche are idyllic. If you have a free choice, we particularly like autumn, when trees are full of colour, the apple harvest gets underway, there are few tourists and plenty of coquilles st jacques (fresh local scallops). Spring is also lovely, with the Coutances jazz festival in May and the D-day anniversary commemorations in June.
In terms of climate, it's similar to southern England - some people call Normandy the French Devon. So be prepared for rain at any time of year, but hope for sun - and you'll probably get a mixture.
