Mongolia Will Freeze You Into Philosophy; Chile Will Just Confuse Your Wardrobe

🇲🇳 Mongolia vs 🇨🇱 Chile — Weather and How Locals Cope

By Suki Nakamura, Out of Office

Some countries have weather. Mongolia and Chile have climate as a personality trait, a national identity so entangled with temperature that you cannot understand either place without first understanding what it's like to be permanently, structurally at the mercy of the sky. Mongolia gives you one of the most brutal winters on the planet and expects you to be cheerful about it. Chile gives you a single country stretched across nearly forty degrees of latitude, meaning you can get sunstroke in the Atacama and frostbite in Patagonia on the same national holiday.

I have shivered through a Ulaanbaatar January that made a Canadian friend of mine, a person who grew up thinking -30°C was a personality flaw she'd overcome, genuinely reconsider her life choices. I have also stood in San Pedro de Atacama watching my skin attempt open rebellion against the driest place on Earth, then flown four hours south to Puerto Montt and needed a jumper by dinner. Both countries have made peace with extremity in completely different ways, and both will judge you, subtly but unmistakably, for how badly you handle it.

Do's & Don'ts

🇲🇳 Mongolia

🇨🇱 Chile

Mongolia: Cold as a Way of Life, Not an Inconvenience

Ulaanbaatar is, depending on the year, one of the coldest capital cities on Earth, and Mongolia treats this not as a crisis to be managed but as a baseline condition to be organised around, the way other countries organise around having a coastline. Winter temperatures regularly drop below -30°C, and the response is not panic but infrastructure: coal and dung-fired stoves in the ger districts, extraordinarily effective traditional deel coats that modern technical fabric still struggles to outperform, and a cultural stoicism that treats complaining about the cold roughly the way complaining about gravity would be received elsewhere — technically valid, socially useless.

What foreigners consistently underestimate is the dzud — a specific Mongolian weather phenomenon combining a dry summer with a catastrophically harsh winter, capable of wiping out enormous percentages of a herder's livestock in a single season. This isn't abstract climate trivia; it's the defining economic risk for a huge portion of the rural population, and it shapes everything from insurance products to internal migration to Ulaanbaatar's ballooning, under-resourced outskirts. If you're doing business or research connected to rural Mongolia, understanding dzud risk isn't optional colour, it's the whole plot.

The ger itself deserves more respect than visitors typically give it. It looks rustic; it is, in fact, a brilliantly engineered response to an environment that would kill most Western tent designs within a night. The central stove, properly fed, will hold a livable interior temperature against exterior cold that would otherwise be lethal within hours. Guests who treat the stove as quaint rather than critical, who let it die overnight "to save fuel," learn the lesson exactly once and never repeat the mistake.

Summers, by contrast, can hit 30°C on the same steppe that was -30°C months earlier — a seasonal swing of sixty degrees that would be considered meteorologically implausible almost anywhere else and is, in Mongolia, just the calendar. Nobody here finds this remarkable. You will. Get over it quickly; the locals have no patience for foreigners who treat a fundamental feature of their homeland as a novelty.

Chile: One Country, Several Climates, No Apologies

Chile's geography is a joke that keeps punching: a country over 4,300 kilometres long and rarely more than 350 kilometres wide, draped down the edge of South America like it's trying to touch as many climate zones as physically possible out of sheer ambition. The Atacama in the north is the driest non-polar desert on the planet — some weather stations there have never recorded rainfall in the history of measurement. Patagonia in the south delivers wind that will physically alter your walking gait and cold that owes more to Antarctica, sitting just across the water, than to anything most people associate with South America.

Santiago sits in a valley basin that, come winter, traps its own pollution with mountain-ringed efficiency, producing smog alerts that catch newcomers off guard precisely because they arrived expecting the crisp Andean air of the postcards, not a city occasionally advising residents to limit outdoor exercise. The camanchaca — the thick coastal fog that rolls in along much of the country's shoreline, particularly around Valparaíso and further north — will drop a supposedly sunny beach day into damp, grey disappointment with no warning and no negotiation.

What Chileans have built, out of geographic necessity, is an almost professional-level fluency in microclimates. Ask a Santiaguino about weather in their own city and you'll get a genuinely granular answer — which neighbourhood runs five degrees warmer, which one catches the worst of the winter inversion layer, when to bring a jacket even in January. This isn't small talk, it's survival literacy, passed down the way other cultures pass down cooking technique.

The UV exposure in the north deserves its own paragraph of respect. San Pedro de Atacama and the surrounding high-altitude desert regularly register UV index readings that would be considered emergency-level almost anywhere else, treated locally as Tuesday. Tourists who ignore this burn spectacularly, often within an hour, and the resulting sunburn stories are a minor but consistent genre of expat forum content, always written with the specific mortification of someone who was warned and didn't listen.

The Verdict

Mongolia's weather is more extreme in the moment; Chile's weather is more exhausting in its refusal to be consistent. If you want a single, honest, brutal winter that teaches you something about resilience, Mongolia will deliver it without theatrics. If you want a country that will make a fool of your packing list no matter how carefully you research it, Chile wins by geographic design. Neither place will coddle you. Mongolia respects you for enduring; Chile respects you for adapting on the fly. Pick your survival skill accordingly, and pack more than you think you need either way.

What Nobody Warned You About

Reddit r/Mongolia — "Nobody told me my phone would just die from the cold walking to the shop. Learned to keep it in an inside pocket the hard way."

Reddit r/chile — "Flew from 38°C in the Atacama to 4°C in Punta Arenas in one day. Same country. I hate it here. I also love it here."

expat.com Santiago forum — "The winter smog is genuinely worse for my asthma than anything I dealt with back home. Nobody mentions this before you move."

Conclusion

Both countries will make you a better packer and a worse person to travel with, because you'll never stop bringing a jacket "just in case" for the rest of your life. Mongolia teaches endurance in a single unrelenting direction. Chile teaches vigilance across a dozen microclimates that refuse to hold still. Move to either expecting the weather to behave the way it does at home, and you will be spectacularly, publicly wrong within the first week. Move expecting nothing, and both countries will still surprise you — just in opposite directions, and roughly forty degrees apart.
