When is the best time to visit Chilean Patagonia?

January and February - the southern summer. In the Aysén region these are the warmest months (daily highs around 20 °C), the driest part of the year and the longest days: in mid-January there is more than fifteen hours of daylight. December and March are also acceptable, just cooler and wetter.

How do I get to the Aysén region?

The gateway to the region is Balmaceda Airport (BBA) with direct flights from Santiago de Chile; the flight takes about 2.5 hours. From Balmaceda it is an hour by car to Coyhaique and another hour to Puerto Aysén. From Prague you always fly with two to three connections, typically via Madrid or Barcelona and then via Bogotá or Lima to Santiago.

How much does a flight from Prague to Patagonia cost?

When searching in August 2026, a return flight Prague - Balmaceda for a date in the second half of January 2027 started at CZK 32,400, but with 44 hours of travel. Connections under 30 hours started at CZK 35,600. The cheapest options take up to 44 hours, so it pays to filter by travel time, not just by price.

When should I buy a flight to Patagonia?

Five to six months in advance. For a date in the second half of January, that means deciding by November at the latest. Outside the peak season the flight will not be cheaper: when searching in August 2026, a return flight Prague - Balmaceda for the second half of January 2027 started at CZK 35,600 for connections under 30 hours, while for the first half of March 2027 it started at CZK 40,100 for connections under 34 hours. The price is not driven by the European season but by the occupancy of the connecting flight from Santiago to Balmaceda, which is served by only a few flights a day.

How much daylight is there in Chilean Patagonia in January?

In the Aysén region, at the 45th parallel south, there is approximately 15 hours and 10 minutes of daylight in mid-January - the sun rises around a quarter past six and sets after nine in the evening. At the beginning of February it is 14.5 hours, at the beginning of March 13 hours, and on June 21 only 8 hours and 40 minutes. Day length is the main practical reason to go in January or February.

How long does the journey from Prague to the Aysén region take?

The fastest connection Prague - Balmaceda takes about 30 hours one way, with two to three transfers (typically Madrid or Barcelona, then Lima or Bogotá, then Santiago de Chile). The cheapest options take up to 44 hours. Because of the length of the journey, it does not pay to plan a stay shorter than ten days.

When to Fly to Patagonia: Months, Light and Flights

The most common question I get is not about the price. It is: when should I actually go?

The short answer: January and February. The rest of this article is about why, and why in Aysén it works a little differently than in the rest of Patagonia.

The short answer

January and February: warmest, longest daylight, least rain. The southern summer in full force.
December and March: one to three degrees cooler and wetter, but quieter and cheaper.
June to August: the southern winter. Empty roads, snow, eight and a half hours of daylight. Beautiful, if that is exactly what you are coming for.

Golden light over the fjord and mountains in the Aysén region — In mid-January the day runs over fifteen hours. The light stays low and long.

Month by month

The numbers below are long-term averages for Coyhaique, the region's capital. It lies on the eastern, drier side of the Andes, in Puerto Aysén it rains roughly twice as much, and on the outer fjords more still. Take this as a guide, not a forecast.

Month	Day / night	Rainfall	Rainy days	Daylight
November	16 / 6 °C	60 mm	8	15 h
December	18 / 8 °C	60 mm	8	15.5 h
January	20 / 9 °C	55 mm	8	15 h
February	20 / 8 °C	45 mm	7	14 h
March	17 / 7 °C	75 mm	9	12.5 h
June	6 / 0 °C	140 mm	14	8.5 h

The most telling column is the last one. In mid-January you have over fifteen hours of daylight, the sun rises around a quarter past six and sets after nine in the evening. In June, eight and a half hours. That is not a difference in comfort; it is a difference in what you can get done in a day.

And then there is the thing the table cannot show. In Patagonia, all four seasons take their turn within a single day. Sun in the morning, rain at noon, an icy wind off the Andes in the afternoon, a clear sky in the evening. The wind is strongest in summer. Anyone expecting stable weather is going wrong, not in the wrong month, but with the wrong expectations.

How you fly there and what it costs

The gateway to the region is Balmaceda Airport (BBA). From Santiago de Chile it is a flight of about two and a half hours, from there an hour by car to Coyhaique and another hour to Puerto Aysén. Further west, the road ends.

From Prague, that means two to three connections, typically via Madrid (sometimes also Bogotá or Lima) to Santiago and on to Balmaceda. When I searched in August 2026 for a return flight for our dates in the second half of January 2027, it looked like this:

from CZK 32,400 return, Prague–Balmaceda
fastest connection about 30 hours of travel one way
but the cheapest options up to 70 hours: with this destination it pays to look at time, not just price

"The flight is too expensive" is a sentence I hear regularly. Thirty-two thousand for a journey to the other end of the world is not much. What is too much is flying there and staying a week.

When to buy a flight

This is where the most common mistake is made: waiting for the flight to get cheaper outside the peak season. It will not. I tried the same search for a March date and it came out more expensive.

Second half of January 2027: from CZK 35,600 for a connection under 30 hours; the absolute cheapest option CZK 32,400: but with 44 hours of travel.
First half of March 2027: from CZK 40,100 for a connection under 34 hours. Four to five thousand more than in January.

The reason is simple: no direct route from Europe reaches Balmaceda, and the final leg from Santiago is served by only a few flights a day. Prices here are not driven by the European season, but by how full the connecting flights are. Therefore:

Buy five to six months in advance. For a January date, that means deciding by November.
Filter by travel time, not by price. The difference between 30 and 44 hours costs three thousand and two days of your life.
Watch the connecting flight to Balmaceda separately. January and February are also the Chilean summer holidays, and domestic flights south are at their busiest of the year.
Plan for one night in Santiago on the way there. A same-day connection looks good on paper: until something is delayed.

Why the second half of January, specifically

Our first expedition goes into the fjord January 20 to February 3, 2027. That is no coincidence:

Some of the longest days of the year and the warmest water in the fjord, 8 to 14 °C.
On January 28, Puerto Aysén celebrates the town's anniversary. We will be there.
February already starts cutting into the daylight: by early March there is two hours less of it.

If you are choosing between Aysén and the far south for January, see Aysén or Torres del Paine?

A boat wake under a storm sky in the Aysén channels — It rains even in the best month. You do not plan around the weather, you plan to adapt.

When not to go to Aysén

If you need certainty about the weather. You will not get it in any month.
For less than ten days. The journey alone swallows nearly two days each way. A week-long trip means you barely find your bearings.
If you want signal. Mobile coverage works in Coyhaique, in Puerto Aysén and along the main road. In the fjord, zero.

The most important thing is not the month

For thirty-seven years I kept telling myself I would go to Patagonia "someday". Someday is not a date.

The best time is January and February. The best date is the one you write in your calendar and then buy the flight around.

When would you want to go, and what is still holding you back?
