As with many places around the globe, the not-too-hot, not-too-cold shoulder seasons of spring and fall are wonderful times to visit Argentina. Since the Southern Hemisphere has opposite seasons to us here in the Northern Hemisphere, spring comes around from September through November, and fall is from March to May. The comfortable temperatures and smaller crowds you'll find during these times of year make for a more enjoyable experience on Argentina guided tours.
December through February marks the summer season in Argentina, which brings muggy weather and more crowds to Buenos Aires. Patagonia is also a popular destination for visitors who set out on Argentina travel packages during the summer, when the southern region experiences warm, sunny days. However, strong winds also blow through Patagonia during the the summer, and then lessen during spring and fall. Cold, rainy days are common during the winter, which goes from June through August.
