The best time to visit Patagonia runs from November to March, during the southern summer. Days are long, the trails around El Chaltén and Tierra del Fuego are open and boat excursions run. December to February is peak season; November and March offer a good compromise between weather, crowds and prices. From April to September it is cold and some services close, except for skiing and whale watching on the Atlantic coast.
The seasons are the reverse of those in the Northern Hemisphere. Argentine Patagonia stretches from the Bariloche lakes to Tierra del Fuego, and from the Andes to the Atlantic: the climate varies with latitude, altitude and exposure to the westerly wind. This guide relies on the official climate normals of the Servicio Meteorológico Nacional (SMN), the Argentine weather service.

Patagonia weather month by month
The table gives the normals for El Calafate, gateway to the Perito Moreno Glacier and El Chaltén. The town is dry, sheltered by the Andes: it rains very little, but the wind often blows hard. Closer to the glaciers and peaks, it rains and snows much more.

Patagonia’s seasons
Southern summer (December to February): peak season
This is the safest time for hiking: around 19 °C (66 °F) in the afternoon in El Calafate, about 13.6 °C (56 °F) in Ushuaia, and days that stretch late into the evening. Boats on Lake Argentino and the Beagle Channel run at full capacity, and Antarctic cruises leave from Ushuaia.
- Pros: trails and refuges open, glacier excursions, long days, all connections running
- Cons: prices at their highest, fully booked accommodation in El Chaltén and El Calafate, often very strong wind, busy trails
Southern autumn (March to May): the colors
In March, temperatures remain decent (16.6 °C (62 °F) average high in El Calafate) and crowds thin out. In April, the lenga forests turn red and orange around El Chaltén and Ushuaia, but nights approach 0 °C (32 °F). In May, winter sets in and many accommodations close.
- Pros: autumn landscapes, fewer people, falling prices
- Cons: days shortening quickly, reduced boat schedules, end-of-season closures
Southern winter (June to August): cold and skiing
Average minimums fall below 0 °C (32 °F) in El Calafate from May to September (−4.4 °C (24 °F) in July), and the maximum barely exceeds 5 °C (41 °F). The Perito Moreno Glacier remains open to visitors, but much of El Chaltén closes. It is ski season at Cerro Catedral (Bariloche) and near Ushuaia. Bariloche receives most of its precipitation in winter (168 mm (6.6 in) in June).
- Pros: snowy landscapes, skiing, very few visitors around the glaciers
- Cons: short days, sometimes icy roads, limited hikes, reduced services
Southern spring (September to November): the awakening
Services reopen gradually in October and the season is well under way in November. The wind is often strong at this time. On the Atlantic coast, spring is an interesting time for the wildlife of Península Valdés.
- Pros: moderate prices, trails still quiet in November, lengthening days
- Cons: unsettled weather, possible snow at altitude early in the season, not all services open in September–October

Bariloche and the Lake District
Northern Andean Patagonia is the mildest in summer (23 °C (73 °F) in the afternoon in January) and the wettest in winter, often as snow at altitude. December to March for hiking and the Seven Lakes road, July to September for skiing. The Argentine winter holidays, in July, draw many people there.
Atlantic coast: Puerto Madryn and Península Valdés
The coast is dry (less than 30 mm (1.2 in) per month at Trelew) and warmer in summer, with an average high of nearly 29 °C (84 °F) in January. The calendar is set mainly by wildlife: southern right whales in winter and southern spring, Magellanic penguins during the southern summer. Dates vary by year and species: check with the Chubut province tourism office or with operators before fixing your trip.
El Calafate and El Chaltén
November to March. El Calafate is dry and windy; El Chaltén, at the foot of Fitz Roy, gets more rain and cloud. Allow spare days: the summit of Fitz Roy can stay hidden for several days in a row. In winter, most of El Chaltén closes.
Ushuaia and Tierra del Fuego
The climate there is cool and damp all year: the average high does not exceed 14 °C (57 °F), even in January, and it rains or snows a little every month (30 to 47 mm (1.2 to 1.9 in)). December to March for Tierra del Fuego National Park and the Beagle Channel; winter is for skiing and snow activities.
Chilean Patagonia
On the Chilean side, Punta Arenas has a climate close to Ushuaia’s (16.3 °C (61 °F) in January, 4.9 °C (41 °F) in July). Torres del Paine National Park, a few hours’ drive from El Calafate, follows the same rhythm: November to March. For this side of the border, see our page on when to go to Chile.

Patagonia month by month
January: Heart of summer: 19.1 °C (66 °F) in the afternoon in El Calafate, 13.6 °C (56 °F) in Ushuaia. Trails open, crowds and prices at their highest.
February: Still summer, with slightly fewer people at the end of the month. Excellent for El Chaltén and Tierra del Fuego.
March: One of the best months for the weather/crowds balance: 16.6 °C (62 °F) in El Calafate, first autumn colors.
April: Red and orange forests, but nights close to 0 °C (32 °F). Some services close at the end of the month. Beware of Holy Week.
May: Winter arrives: night frost in El Calafate (−1.7 °C (29 °F) average minimum), many closures.
June: Winter, short days. Perito Moreno Glacier open to visitors, El Chaltén largely closed.
July: The coldest month (−4.4 °C (24 °F) average minimum in El Calafate). Skiing at Bariloche and near Ushuaia, Argentine winter holidays.
August: Still winter, few visitors. A good time for skiing.
September: End of winter, gradual reopenings. Atlantic coast interesting for wildlife.
October: Windy, cool spring. The season restarts in El Calafate and El Chaltén.
November: Season under way, still few crowds: a very good month, with gentler prices than in January.
December: Start of high season and long days. Book early for the holidays.
When to book your trip to Patagonia
For December to February, book 4 to 6 months ahead: the accommodation in El Chaltén, El Calafate and Ushuaia is limited, and domestic flights from Buenos Aires fill up fast. For Torres del Paine, the park’s refuges and campsites often go several months ahead. In November or March, 2 to 3 months is usually enough.
Planning your trip to Patagonia
- Entry requirements: rules depend on your nationality; see the entry requirements for Argentina and the entry requirements for Chile before you travel.
- Time difference: see our time difference guide for Argentina to compare it with your home city.
- Currency: Argentine peso (ARS); Chilean peso (CLP) on the Chilean side. Prices change quickly in Argentina: our currency converter helps estimate your budget.
- Health and mountains: the U.S. Department of State (travel.state.gov, last updated July 16, 2026) strongly discourages hiking alone or separating from your group on a trail in Argentina, advises hiking in groups and following the advice of park rangers and search and rescue teams. See also our list of what to pack for clothing suited to wind and cold.
Frequently asked questions
What is the best month to visit Patagonia?
January and February offer the most favorable weather, but also the most people. November and March are the best compromises: trails open, long days, fewer crowds and gentler prices.
Can you visit Patagonia in winter?
Yes, for skiing at Bariloche or near Ushuaia, or to see the Perito Moreno Glacier without the crowds. However, it freezes at night in El Calafate, days are short and much of El Chaltén closes.
Is Patagonia cold in summer?
Cool rather than cold: about 19 °C (66 °F) in the afternoon in El Calafate in January and 13.6 °C (56 °F) in Ushuaia, with nights between 5 to 7 °C (41 to 45 °F). Wind and rain quickly lower the felt temperature.
When can you see whales in Patagonia?
Southern right whales visit Península Valdés during the southern winter and spring. Exact dates vary from year to year: check them with the Chubut tourism authorities or local operators.
When should you visit Chilean Patagonia?
As on the Argentine side, from November to March. Punta Arenas has normals close to Ushuaia’s, and Torres del Paine National Park is most accessible during the southern summer.
Is Patagonia windy all year?
Yes, the westerly wind blows frequently, with strong gusts especially in spring and summer. Pack a windbreaker and leave room in your itinerary for canceled excursions.
