Buenos Aires in December

When to go

In December the WMO normals from Argentina's national weather service show warm afternoons, mild nights and rain on several days of the month, so pack for warm weather and the odd wet day. Argentine law makes the Immaculate Conception, early in the month, and Christmas Day fixed national holidays, and lets the national government add tourism days each year, so check the official calendar for this year's dates and opening hours around them.
