Generally, Brittany is warmer than the South of England, all the year round.
In winter time, Brittany benefits from a remarkably mild climate – frost and snow are relatively rare. In the Côtes d’Armor the waters of the north coast are one or two degrees warmer on average than those on the south coast, on account of the Gulf Stream which flows up the English Channel
The mildness of the climate has been a strong factor in the development of tourism in Brittany, but also for the region’s agricultural sector. Nurseries growing plants under glass or in open fields provide early crops for the French market and for other parts of Europe, particularly with crops that are not heavily exported from the warmer areas of southern Spain.
In the months of July and August it can be very hot. Early Summer and Autumn are usually warm and mild and a good time to visit
