Remember that in the southern hemisphere seasons are the opposite
to those in the northern hemisphere. In general, the summer is the
best time to visit Patagonia and the Southern Andes because of the
mild temperatures and long days. Wintertime is recommended for
travelling to the North and Northwest as rains are less frequent
and tropical temperatures drop a few degrees. Autumn and spring are
marvelous in Buenos Aires, Cuyo and the pre-mountain range areas of
La Rioja and Catamarca.
