Base Torres hike in summer, spring, autumn or winter

Summer is when Base Torres is busiest and brightest. Las Torres Patagonia, the concession that manages the land around the trailhead, puts the average summer temperature around 18°C, with a range from a low of 1°C to a high of 23°C.^16,17 Those are park-wide figures. The lookout sits higher and more exposed than the hotel lawns, and on top you should expect the cold end of that range. Plan to pull a fleece and a shell out of the pack at the top, even in January.

Wind is the summer story. The same source puts the park's wind anywhere between a steady 20 km/h and bursts reaching 110 km/h, and it names summer as the windiest season.^4,3 On the trail that matters most on the exposed pass before Refugio Chileno and on the open moraine, where there is nothing to hide behind. Hold the poles short and keep a hand free. Gusts come in bursts, so stop, crouch and wait them out rather than pushing on mid-step.

The upside is time. In December, January and February hikers may leave Laguna Amarga as late as 10:00, and the lookout stays open until 16:00, the widest window of the year.⁶ The park gates open from 07:00 to 21:00 in January and February, so a late summer evening still leaves room to get back to the car or the bus.¹⁸ Las Torres also counts summer in its high season, with more visitors on the trails.¹⁹

March and April bring the lenga forest into colour. Las Torres speaks of red and orange leaves across the park in these months, and CONAF names lenga as the dominant tree of the park's deciduous woods, the forest you cross below the moraine.^26,31 A still autumn morning under those leaves is a reward in itself. Colours change week by week, and a calm day lets you hear the river under the trees.

The air cools quickly. Las Torres gives autumn a range from a low of -1°C to a high of 11°C on one page and an average near 13°C for March to June on another, and it calls April very cold but with milder winds and fewer people.^21,32,19 The trail window narrows too, with a latest start of 09:30 and a closing time from the lookout of 15:00 in March and April.²⁴ Shorter afternoons make an early start more important than in summer.

Services wind down at the end of April. Refugio Chileno closes on 25 April 2027 and the Welcome Center at the trailhead on 27 April 2027, so a late-April hike has fewer places to warm up or buy water.^15,14 The park gates still open at 07:00 in April and close at 19:00, a reminder that the evenings are getting shorter.¹⁸ Bring a warm hat and gloves even if the morning in town feels mild.

Closures are part of the season, not an exception. The park's bulletin says rangers inspect trail conditions every day and that access may close without prior notice because of high winds, river flooding or severe weather.⁹ It is worth knowing this before you plan a single fixed day for the hike in your itinerary. The towers will still be there tomorrow, and a closure is the park doing its job.

A recent example shows how it works. CONAF closed the Mirador Base Torres trail and several other paths from 10 November 2026 on a preventive alert for wind gusts, rain and likely storms, with reopening estimated for 12 November 2026.^10,38 Las Torres Patagonia reported the same closure on its news page, citing forecast gusts for 9 and 10 November.³⁹ Closures like this come with little warning, so follow the park's own channels in the days before your hike.

For a booked day hike, the listing itself says the activity may be changed or cancelled for unsafe weather, and it carries free cancellation up to 24 hours in advance. That is the useful combination in a windy season. If you can, keep a spare day in Puerto Natales after the hike date, so a closure moves your walk instead of cancelling it. It also takes the pressure off a hike in poor visibility.
