Brittany in October

May through September offers the warmest weather and longest days, with July and August bringing crowds and higher prices. June hits the sweet spot – warm enough for beach days but still quiet enough to find parking in Concarneau. September extends summer with fewer tourists and calmer seas, perfect for coastal walks. The shoulder months of May and October can be magical if you don't mind cooler temperatures and the occasional rainstorm. Winter brings dramatic seas and cozy fireplaces, but many coastal restaurants close until Easter.
