The regional winds of Brittany to know to navigate safely

We have all heard of the Tramontane and the Mistral, these regional winds that blow over certain regions of mainland France. But there are many others to know in order to navigate safely when you want to set sail in a new region. Today, we focus on the winds of Brittany.


Regional winds

The wind is what corresponds to the movement of air in the atmosphere. There are 4 kinds of winds :

  • seasonal winds

  • regional / local winds

  • cyclonic winds

  • anticyclonic winds

In the French metropolis, there are many regional winds which appear according to the relief present on a zone. They are designated by specific names. But you have to be careful because a wind has several names depending on the region in which it blows. For example, the Mistral in Corsica is called "Maestrale", or "Magistrau" in some areas of Occitania.

The locals know them well but it is not always easy to find your way around when you don't know the region in question. It is better to find out what winds are blowing in the region where you want to launch your boat, whether it is a sailboat or a motorboat.

Discover the top 4 regional winds in Brittany that we have chosen to present you.
