If you asked me to describe Patagonia’s weather in one word it would be quite simple — unpredictable.
Any experienced local guide would say the same, and might add, “You can experience all four seasons in one day here”, which couldn’t be more true.
Although it’s typical for travellers to expect a comprehensive forecast for the day’s activity or excursion, it’s important to understand that rain, snow, sunshine and rainbows can all be seen on any given day, or at any given hour!
It’s completely normal to be on an excursion where one moment you’re taking off layers to stay cool, and the next you’re bundling up for a sudden blizzard or shoving on waterproof gear for horizontal rainfall.
Patagonia’s richly diverse landscape includes glaciers, mountains, rivers, valleys, fjords, and pampas, creating unique microclimates for you to experience.
Winds of change
If there’s one thing you can be pretty sure of, it’s wind.
The huge region of Patagonia spans from around 40 to 50° latitudes in the Southern Hemisphere, which receives some of the strongest westerly winds in the world. Torres del Paine National Park, for example, is situated at a latitude of 51°, where warm air from the equator collides with cold air travelling north from Antarctica. As a result, westerly winds are forced east to the tip of the continent where the Pacific and Atlantic oceans converge. The place feels so extreme. You really get the sense you’re at the World’s End.
It’s important to understand that there are few land masses across Patagonia’s vast desert and steppe to act as barriers and slow down westerly winds.
Winter calm
Despite its unpredictable weather patterns, Patagonia’s winter months are surprisingly stable. With strong winds and heavy rain throughout the year, winter brings a sense of tranquillity. It’s as if nature, and the landscapes themselves, slow down to enjoy a rest.
During winter, expect short, chilly days with snow-covered mountains and valleys. The average daylight period throughout the day is only 8-10 hours, with sunrise beginning at 10am and sunset by 6pm. June and July are the coldest and driest months.
Ready for rain
Another of the elements you’re likely to encounter on your trip is rain. Often without much warning.
I’d recommend packing a reliable waterproof jacket, sturdy waterproof boots, and a durable rain cover for your backpack. Quick-drying layers are also indispensable, allowing you to embrace the sudden shifts in weather.
Plus, don’t rule out a compact and portable umbrella for greater shelter during those unexpected downpours.
Strength of the sun
When I first travelled to Patagonia, this was the first thing that struck me about the climate. My lips were constantly dry and I felt like I was always burnt on my neck and face. This is because one of the largest holes in our ozone is directly above Patagonia.
Even if you cannot feel it, the sun is incredibly strong, and it can cause serious sunburn in a very short time. Sunscreen (and a lip protectant) are highly recommended while travelling.
Seasons change
Remember the southern hemisphere runs on the opposite schedule to the north; so winter is summer, summer is winter. Here’s a little breakdown to help you further:
Spring: (September, October, November) Warm daytime temperatures, chilly nights, strong winds, and plenty of rain. Days begin to grow longer and the climate begins to transition with erratic weather conditions, which can make for interesting days — truly experiencing all four seasons in one day!
Temperature range: 3-7ºC (the low 30s°F) to 14-18ºC (the mid-60s°F).
Summer: (December, January, February) During this time of year in Patagonia, you can expect warm days and cool (but not too cold) nights. This is the season when Patagonia’s notorious winds are at their most powerful, even exceeding 120 miles per hour. Be prepared for rain although it can feel much hotter because of the strong UV rays.
Temperature range: 6-8ºC (the low 30s°F) to 17-20ºC (the upper 60s°F).
Autumn: (March, April, May) During the fall, the northern regions of Patagonia experience warm and sunny days with clear skies. However, the southern regions are colder, with chilly nights and even snow towards the end of the season. Days begin to grow shorter with 9-13 hours of daylight as winter solstice approaches and
Temperature range: 3-7ºC (the upper 30s°F) to 14-18ºC (the mid-60s°F).
Winter: (June, July, August) Despite the cooler, crisp air—Patagonia’s winter months are much more stable than summer and spring. Days, although shorter (8-10 hours of daylight) are calm and peaceful.
Temperature range: -3 to 2ºC (mid-20s to low 30s°F) to 10-14ºC (50s°F).
