Patagonia, a region shared by Argentina and Chile at the southern end of South America, is a dream destination for trekkers worldwide. With its dramatic mountain peaks, vast ice fields, and deep blue lakes, Patagonia offers some of the most breathtaking landscapes on the planet. However, given its extreme southern location, the weather here can be unpredictable, making it crucial to choose the right time for your trekking adventure.

Here's a seasonal guide to help you plan the perfect Patagonian trek.

1. Summer (December to February)

Peak Trekking Season

Summer is the most popular time to trek in Patagonia, and for good reasons. The weather is at its warmest (though still quite variable), the days are longest, and all the trails and tourist services are in full swing.


  • Warmest temperatures (can reach up to 20°C or 68°F)

  • Long daylight hours, meaning more time to explore

  • All trails and services are open


  • Popular trails can be crowded

  • Accommodation and services need to be booked well in advance

  • Winds can still be strong, especially in open areas

2. Autumn (March to May)

A Time of Tranquility and Colour

Autumn in Patagonia is a spectacular time for those who prefer a quieter trekking experience. The landscape transforms with beautiful autumn colours, and the summer crowds have dissipated. March is our favourite time to go trekking in Patagonia. 


  • Less crowded trails and accommodations

  • Beautiful autumn foliage

  • Milder weather, (10℃ or 50°F) though cooler than summer, and can drop to below freezing at night later in the season

  • Due to less crowded trails, there is more chance of seeing wildlife


  • Days get shorter, reducing trekking time

  • Some facilities start to close towards the end of the season, the Torres del Paine 'O' circuit closes at the end of March

  • Weather can be unpredictable, with a mix of mild days and sudden cold snaps or bouts of rain, with strong winds

3. Winter (June to August)

For the Hardy and Adventurous

Winter trekking in Patagonia is only for the most adventurous souls. Many trails and services are closed, but the reward is a unique and solitary experience in a winter wonderland.


  • Solitude in nature, as few tourists visit during this time

  • Snow-covered landscapes offer a different kind of beauty

  • Ideal for photography with soft light and clear skies


  • Many trails, refuges, and facilities are closed

  • Days are short, and weather can be harsh

  • Suitable only for experienced trekkers with appropriate gear

  • Temperatures hover around 4℃ or 40°F during the day and around -7℃ or 20°F at night

4. Spring (September to November)

The Reawakening of Nature

Spring in Patagonia is a time of renewal and great beauty, with wildflowers blooming and wildlife becoming more active. The weather begins to warm up, and the high season crowds have not yet arrived.


  • Increasingly warmer weather (around 10℃ or 50°F) and longer days 

  • Lowest rainfall

  • Less crowded than summer

  • Ideal for wildlife watching and photography


  • Early spring can still be quite cold and windy

  • Some services may not be fully operational until late spring

  • Unpredictable weather with occasional snowfalls

Choosing the best time to trek Patagonia largely depends on what you want from your experience. Summer offers the best weather and full services but comes with crowds. Autumn and Spring provide a more solitary experience with stunning natural beauty, while Winter challenges the most experienced trekkers. Regardless of when you go, Patagonia promises an unforgettable adventure with its awe-inspiring landscapes and untamed wilderness.
