If you’re not a frequent traveler to South America, it pays to remember that it’s cold here when it’s warm in the Northern Hemisphere and vice versa. The winter months are June to August, summer stretches from December to February, spring unfolds from September to November and the autumn months are March, April and May. There can be high humidity during the summer months, and winter brings foggy nights and misty mornings. Pack accordingly.
If you are invited to an Argentine home, dress well. In fact, Buenos Aires is one of the most fashion-conscious countries in the world so leave your sneakers in your suitcase at night. Men should wear a jacket and tie to dinner, and women should wear a dress or a skirt and blouse.
