Mendoza in January

March through May is perfect — harvest season means festivals, cooler weather, and the mountains are crystal clear. September through November brings spring blooms and fewer crowds. Summer (December-February) gets hot — we're talking 95°F daily — but the mountains offer escape. Winter is mild during the day but nights drop to 40°F. July is ski season at Las Leñas, two hours away. Avoid January if you hate crowds; it's peak Argentine vacation time and prices jump 30%.
