While the Provence has it's Mistral wind the Southern France in Languedoc-Rousillon has it's Tramontane coming in from the North - also bringing in some colder weather. Usually it blows the clouds away. This is from a November day in the first of the usually 5-10 days cycles.
From the net:
The dominant wind of the Languedoc region is the Tramontane. The Tramontane is powerful, dry and cold, and blows from the north or the northwest. It gathers its speed and power in the same way as the Mistral does, passing through the narrow corridor between the Pyrénéan Mountains and the Massif Central, and being created by the meeting of the high pressure from the Atlantic with the low pressure of the Mediterranean in the Golfe de Lion.
The areas of France most affected by the Tramontane are the Languedoc Littoral, that is, the coastal areas of the Languedoc all the way along the west to Spain, and the inland areas of the Hérault , the Pyrénées-Orientales and the southern Aude. In certain areas, notably the eastern Languedoc and the western regions of Provence, the Tramontane can merge with the Mistral.
