The Climate of, and Weather in, the Languedoc:   Wind:   Le Vent Marin.

Le Marin, is a warm marine wind from the Mediterranean Sea. 

It blows from the south-east bringing banks of low humid cloud.   Sea mist can be dense on the coastal plain. 

The wind causes heavy rain in coastal areas in winter. 

In summer the clouds tend to dissipate, but they can hang around for days smelling distinctly of salt.  The wind can be strong, even violent, bringing the heavy rain well inland. 

If the rain does not precipitate, this wind is referred to as a Marin blanc (A white Marin).
