Good news, we are currently right in the midst of the one of the two best times of year to visit Buenos Aires, from April-June (fall) or from September-December (spring). These seasons provide us with mild temperatures, beautiful foliage and very little crowding. During the fall and spring, you can also get cheaper prices for accommodations. Summertime in Buenos Aires (January and February) means heavy crowds and high prices. While summertime is still a popular time to visit, temperatures soar the 90s (F) and the air can be extremely humid. The off-season starts in June and ends in August and is usually filled with rain, cold temperatures, and very few tourists.
