Saint Malo and its fortifications, Pornic and its old port, Brest and its famous maritime festivals, Vannes and its half-timbered houses.

Climate and Weather in Brittany
It's time to forget the clichés about Brittany: no, it doesn't rain every day and the weather is not (so) bad! In most cities, when visiting Brittany, you can enjoy an oceanic climate, with well-defined seasons and microclimates scattered throughout this region of France.
Brittany's Climate in Summer
In Brittany, while temperatures are never stifling, summers are nevertheless sunny, as seen in cities like Vannes and Lorient. The sea breeze slightly cools the atmosphere, providing a salty air in this pleasant season. It should be noted, however, that microclimates exist especially on islands in the Gulf of Morbihan, offering an almost Mediterranean landscape. Although precipitation can occur in Brittany, especially in the center, it remains moderate in the summer.
Brittany in Winter
Periods of frost are quite rare in Brittany, especially in the northern part of the region. In the center of Ille-et-Vilaine, however, it can get very cold with occasional snowfall. Negative temperatures are quite rare on the coast and in the islands. It is worth noting that precipitation is more frequent in Finistère. Wind is also very present throughout this season, and temperature variations are very low. Towards Concarneau, winters are milder, as well as on the Emerald Coast.
Autumn and Spring in Brittany
In Brittany, spring and autumn are relatively pleasant seasons, with mild temperatures, although they can be a bit cool during the autumn months. Humidity is present during these two seasons, with regular but light precipitation. It should be noted that the western interior of Brittany experiences almost constant humidity, with numerous cloudy days, especially in autumn.
