Argentina stretches from the subtropical north to the edge of Antarctica, so there is no single best time to visit. The right month depends on where you want to go and what you want to do. This guide breaks it down region by region, so you can match your route to the weather, avoid closed roads and maybe save some money along the way.
Patagonia: November to March
Patagonia is the classic campervan destination, and the best time is roughly November to March. Days are long (in December it can stay light until after 10 pm in the south), trails around El Chaltén and Torres del Paine are open and campsites are running. January and February are the busiest and most expensive months.
October and April are great shoulder months: fewer people, beautiful spring flowers or autumn colours, but colder nights and more chance of snow. From May to September it is winter. It gets very cold, some roads and passes close, many campsites shut and daylight is short, so a campervan trip in deep Patagonia is not recommended then. The famous wind blows all year, strongest in spring and summer.
The North: Salta and Jujuy
The northwest, with its coloured mountains, salt flats and adobe villages, has a very different rhythm. Summer (December to February) is the rainy season: storms can cause landslides and cut roads, especially in the Quebrada de Humahuaca and on routes to the Puna.
The best windows are March to May, when everything is green after the rains, and September to November, with dry, clear days. Winter (June to August) is dry and sunny but very cold at night, especially at altitude, so it can work if you are prepared for freezing nights.
Mendoza and the wine regions
Mendoza is good for most of the year, but March is special: it is harvest time (vendimia), with the big Fiesta de la Vendimia celebrations and vineyards in full action. Autumn (March to May) brings golden vines and mild days. Summer is hot but perfect for rafting and the mountains; winter is cold, and the high pass to Chile can close because of snow.
Uruguay and the Atlantic coast
The Uruguayan coast is a summer destination, best from December to March. January is peak season, when Punta del Este, La Pedrera and Punta del Diablo fill with Argentine and Brazilian holidaymakers and prices rise. December, late February and March are calmer, still warm and much better value.
Outside summer, Uruguay is quiet and peaceful, with many seasonal businesses closed. Montevideo and Colonia del Sacramento are lovely all year.
Wildlife: whales at Península Valdés
If you want to see southern right whales, head to Península Valdés and Puerto Madryn between roughly June and December, with September and October often considered the best months. Spring also brings penguins to colonies like Punta Tombo, and sea lions and elephant seals can be seen for much of the year. It is a great reason to plan a shoulder-season trip along the Atlantic coast.
Prices, availability and when to book
Campervan prices follow the seasons. At Mate Bus, high season (mid-December to February) costs about 1.5 times the base price, winter (June to September) about 0.85 times, and shoulder months like March to May and October to November use the base price. For many routes, shoulder season gives you the best mix of weather, prices and empty campsites.
In January and February, campervans are scarce across Argentina and Uruguay, as half the continent is on holiday at the same time. Book early: Mate Bus requires a minimum of 21 days lead time, so reserve at least 3 weeks ahead, and for summer, the earlier the better.
