Weather
Most of Argentina is in full spring mode by October and a gorgeous time to visit the central and northern areas. Buenos Aires, the starting point for most international visitors, sees highs in the lower 70s Fahrenheit, while Mendoza and Salta will see highs in the upper 70s and lower 80s, respectively.
You can catch stunning wildflowers across the country especially in the Lakes District this month, and some travelers even plan their trips around these spectacular blooms. Puerto Iguazú, meanwhile, sees highs in the mid-80s with about 10 days of rain a month, making this the wettest part of the country in October.
As for Southern Patagonia, spring doesn’t really arrive until November, since daily highs remain the low 50s, though you'll start to see less rain and longer daylight hours for more outdoor adventures. No matter where you travel, still bring plenty of warm clothing with you for chilly evening temperatures, especially after the sun goes down.
Crowds & Costs
Those who know Argentina know that this is arguably the best month to travel. October falls within the pre-summer shoulder season, which means you'll find lower prices and not-overwhelming crowds in most popular areas. If you can handle the cool weather in Patagonia, you'll beat the flood of international tourists (and pricey accommodation costs) of the peak summer months. Wherever you travel, it's still a good idea to make your reservations at least three months in advance.
Where to Go
When planning your Argentine October adventure, you'll want to consider Northern Patagonia, specifically the Lakes District for spring-time blossoms, and Peninsula Valdes for whale watching. If you are game for cooler temperatures, Los Glaciares National Park is a must for those interested in hiking near Mt. Fitz Roy and seeing massive glaciers like Perito Moreno.
Don't miss Buenos Aires’ ideal spring weather in October where you can experience the city's buzzing neighborhoods and sites before the summer crowds. Even better, pair the capital with a few days in Mendoza to explore this wine-growing region on the edge of the snow-capped Andes. This is a gorgeous place to spend a few nights where you can enjoy the scenery, small city culture, nearby wineries, and notable dining scene.

What to Do
Argentina offers a wealth of outdoor activities in mid-spring. If you choose to travel north of Buenos Aires, there are hundreds of waterfalls to explore by foot, boat, or bike on both sides of the Brazilian/Argentina border at Iguazú Falls. In the northwest is a desert landscape where you can base yourself in the colonial city of Salta and take road trips to explore nearby villages, salt flats, rocky gorges, canyons, and wineries with few international tourists.
Argentina has some of the best hikes available in South America for all levels and abilities thanks to the spectacular Andes mountain range. If you don't make it to Los Glaciares National Park, you'll find plenty of other day-hikes around the country, including Medoza and the Lakes District where the wildflowers are also in bloom.
Since spring comes late to southern Patagonia, it may be best to wait another month before attempting multi-day treks. That said, those who come prepared with proper gear will find few crowds to see the glaciers and famous peaks, as well as wildlife up close.
Events in October
Oktoberfest. Join the beer swillers and German bands at Argentina’s national beer festival, Villa General Belgrano’s Oktoberfest in the Central Sierras. Villa General Belgrano is well known for its German population, who settled in the town after a German warship sunk off the Argentina coast in 1939. During this fest, watch as Argentina becomes old-fashioned Munich with Bavarian dancing, schnitzel, and traditional costumes.
Bariloche a la Carta. This weeklong food festival represents the Lake District’s best culinary offerings. Dozens of restaurants take part, showcasing special menus, and numerous food stalls and microbreweries set up shop in the main square.
Festival Internacional de Ushuaia. Each October, the city of Ushuaia puts on an annual International Festival of Classical Music.
