Mendoza Travel Guide: Geography & Climate

A wine Growers Paradise

The Andean Mountain chain runs along the western side of the Mendoza wine region, acting as a divider between here and the famous wine regions of Chile. This gives the two regions very different characteristics and, consequentially, different characteristics of wine. Mendoza does not share the same influence that the Pacific Ocean has on the Chilean climate, making it a much more dry and arid landscape.

There is around 300 days of sun in Mendoza making the weather most pleasant for travelers, the temperature averages between 70 and 90 degrees Fahrenheit during summer months. This does also mean, however, that irrigation is an essential measure to supply water to the vineyards and other agricultural areas – the city itself is crisscrossed with irrigation canals and small rivers providing water to its parks and natural areas. Plentiful water supplies can be derived from rivers that source from melting glacier water in the Andes and also from boreholes scattered around the region. The suitability of Mendoza for wine growing is amplified by excellent fertile soil that is composed of loose sand layered over clay.
