Travelers should be prepared for unpredictable weather at any time of year. Most travelers consider the warmer months of November to March (seasons are reversed south of the Equator), to be the best time to visit southern Argentina. However, the hottest summer months, (December - February) can be unpleasantly humid in Buenos Aires so travelers that plan on extending their stay in the capital may opt for the shoulder seasons (October - November or April -May) instead. Holiday weeks (Easter and Christmas) tend to be the busiest times so avoid these times if you want to avoid the crowds. Travelers can visit Iguazu Falls year-round, though again the summer months can be incredibly hot. Visitors to Northwest Argentina will also want to avoid these hot summer months. In fact, the best time to visit this area is during the coolest months of May to September. Recommendations for the best time to do each tour are listed on the Argentina Tours page.

In Argentina, we have selected a variety of charming accommodations ranging from cozy mountain lodges to comfortable city hotels with all of the modern conveniences. In general, we use small, family-run accommodations that are locally owned and characteristic of each area instead of luxury chain resorts.

Argentina's climate is as varied as its terrain, ranging from subtropical in the north to humid and steamy in the central region and cold in the temperate south. The Andes region has erratic rainfall, flash floods in summer, searing heat, snow at higher elevations, and the Zonda - a hot, dry wind. The lowlands receive sufficient rainfall to support swampy forests and upland savanna, but rainfall decreases from east to west; shallow summer flooding is common in the east. The winter dry season is pronounced, and the summer heat can be brutal. Patagonia is mild year-round in the east and glacial in the south. Weather in Patagonia can be very unpredictable and can change drastically and unexpectedly. Argentine Patagonia and Tierra del Fuego have summer averages of just 11°C (52°F); nighttime temperatures will most likely be in the 1°C-5°C.

Patagonia is a rugged, mountainous area of southern Chile and Argentina characterized by glaciers, fjords, and windswept steppe. Weather is unpredictable with strong winds and sudden storms common. In the Magallanes and Tierra del Fuego areas, temperatures in summer average 52°F (11°C). Dampness and wind chill can make it feel cooler so be prepared by having a number of layers and good waterproof gear with you. The weather year-round is highly unpredictable, and in summer be prepared for incessant winds that do lessen in the winter. In the shoulder season months - November and March - you are likely to find the winds not as strong as they are during the peak of summer. Summertime (December through February) is the best time to visit as temperatures are generally warmer and trails are more accessible. Shoulder months, October, November, March, and April tend to have cooler temperatures, but also less wind and smaller crowds so these can be nice options as well
