Mendoza’s peak season falls between December and April, which coincides with summer and the wine harvest. Most Mendoceneans flee the city in January, when temperatures hit 90 degrees, to pass their month-long vacation on the breezy shores of Chile. The first week of March, Mendoza celebrates the harvest season with its most impressive festival—Fiesta Nacional de la Vendimia. The winter months July and August attract skiers and snowboarders from around the world to carve up the hemisphere’s premier mountain resort—Las Leñas.
