Mendoza is located at the foot of the Andes Mountains. These mountains greatly influence the weather and climate of this wine-growing region. As a result, the weather in Mendoza is very mild and dry, with more rainfall in the winter months. The overall climate of Mendoza is quite similar to the climate in California. The fresh breezes, bright sunshine and clear skies of the Andes Mountains are very pleasant, but it is important to realize that there are large differences in altitudes and temperatures across the province. Because of these variations, warm clothes are recommended anytime when visiting the region.
