Argentina runs from the subtropical forests of the north to Tierra del Fuego near the southern tip of the continent, with the Andes along its western edge and the flat grasslands of the Pampas in the middle. Most trips combine Buenos Aires with one or two very different regions, often far apart. The whole country keeps one time all year, and its seasons are the reverse of Europe's and North America's.
Argentina for visitors
Almost every trip starts in Buenos Aires, a large, European-feeling city of grand avenues, distinct neighbourhoods such as San Telmo, La Boca and Palermo, cafés, bookshops, tango and late dinners. Day trips reach the delta town of Tigre or Colonia del Sacramento across the river in Uruguay.
Patagonia
Patagonia, the vast, windswept south, is the main draw for many visitors. El Calafate is the base for the Perito Moreno Glacier, El Chaltén for hiking beneath Mount Fitz Roy, and Bariloche, in the northern lake district, for lakes, forests and, in winter, skiing. On the Atlantic coast, the Valdés Peninsula is known for whales, sea lions and penguins, and Ushuaia, on Tierra del Fuego, is one of the world's southernmost cities and the main port for Antarctic cruises.
Iguazú, Mendoza and the north-west
Iguazú Falls, on the border with Brazil, is a long chain of waterfalls in subtropical rainforest; the Argentine side has the most walkways, right above the falls. Mendoza, at the foot of the Andes, is the heart of Argentina's wine country and the gateway to Aconcagua, the highest mountain in the Americas. In the north-west, Salta and Jujuy have colonial towns, Andean villages and red and multicoloured canyons such as the Quebrada de Humahuaca.
Getting around
Distances are huge: Buenos Aires to Ushuaia is a long flight, and most visitors fly between regions, usually via Buenos Aires. Long-distance buses are comfortable, with reclining seats on overnight routes, and reach almost every town. Passenger trains are limited. Renting a car works well in the north-west, Mendoza and parts of Patagonia, where roads are long, straight and quiet.
Time in Argentina
All of Argentina is on one time zone. The time zone database lists several identifiers for its provinces, but today they all share the same offset: Buenos Aires uses America/Argentina/Buenos_Aires, Argentina Time, which is UTC−3 all year. Argentina does not use daylight saving time, so the clocks never change.
That offset is ahead of what the sun would suggest for most of the country, so sunrise and sunset come late by the clock, especially in the west and in winter. In Buenos Aires the sun rises at about 08:00 in late June and sets at about 20:06 in late December, and further west, in Mendoza or Patagonia, mornings are darker still.
Because Europe and North America change their clocks, the gap with Argentina changes twice a year. Right now Buenos Aires is 3 hours behind London and 2 hours ahead of New York, and it keeps the same time as São Paulo. Flights from Europe are long overnight journeys with a modest time change, so jet lag is usually milder than the flight time suggests.
Climate and weather
Argentina's climate changes with latitude and altitude. The north-east, around Iguazú, is subtropical, hot and humid, with rain all year. The north-west is drier, with warm days and cold nights in the high valleys and summer rains. Mendoza and the land along the Andes are arid and sunny. The Pampas and Buenos Aires have a humid subtropical climate with hot summers and mild winters. Patagonia is cool, dry and very windy, and Tierra del Fuego is cold for much of the year, with snow on the mountains even in summer.
In Buenos Aires, average highs range from 14°C in July to 28°C in January, and the city gets about 1,107 mm of rain a year, spread across all months with somewhat less in winter. The Buenos Aires guide has the full month-by-month picture.

São Paulo, on its plateau in Brazil, has much milder winters and a less marked difference between the seasons. In Argentina, the south is much colder than either city, and the capital's figures say nothing about Patagonia, where the wind often matters more than the temperature.
Best time to visit Argentina
Seasons follow the southern hemisphere, with summer from December to February and winter from June to August. For Buenos Aires, spring and autumn are the most pleasant times, warm but not humid; summer is hot and sticky, and many residents leave the city in January.
Patagonia is a summer destination. The hiking season around El Chaltén and the glaciers runs from late spring to early autumn, when days are long; it is also the busiest period. In winter many trails, roads and services in the far south close, although Bariloche and the resorts near Mendoza are busy with skiers. Whale watching on the Valdés Peninsula runs from winter into spring.
The north-west is best from autumn to spring, when it is dry; summer brings rain that can cut mountain roads. Iguazú can be visited all year, but summer is hot and humid, and the falls carry the most water after heavy rain. Mendoza's vineyards are at their most attractive in autumn, around the grape harvest.
