Is it always rainy in Brittany? Brittany has the (wrongful) reputation of being a wetland. The current climate of Brittany is an oceanic climate with dry summers and mild but wet winters.
On the North coast, in the West and in the interior of Brittany the climate is a little more humid. On the south coast, the climate is drier.
As much sun as Biarritz
After that period come summer. It starts around mid-June and lasts untill mid-October. In high season, the average temperature is 25°C.
It is around Carnac and the Gulf of Morbihan, along the coast of South Brittany, that you will find the most hours of sunshine (more than 2000 per year, comparable with Biarritz).
Thus, in spring and autumn, holiday makers enjoy high temperatures and a pleasant time and can still take full advantage of the beaches of South Morbihan...
