Saint-Chinian has a Mediterranean climate, with hot, dry summers and fairly mild winters. However, it is close to the mountains (Montagne Noire and Monts de l'Espinouse), which bring a certain coolness to these "terroirs". The wind plays a key role in the area. It can occasionally be a nuisance, breaking young shoots and thereby reducing the harvest, but it has the advantage of reducing the level of moisture in the plants (limiting the spread of Mildew) and around the grapes (reducing problems of rot). This means that the vines need to be sprayed less and the grapes can be left to ripen in peace.
