Seasonal Weather in Santiago: What to Expect Throughout the Year (It's Complicated)

okay, so santiago. it’s…a lot. i mean, it’s beautiful, don't get me wrong. mountains practically hug the city, and there’s this constant, hazy glow. but the weather? forget about predictable. it’s a rollercoaster disguised as a mild climate. i'm a freelance photographer, so i'm extra sensitive to this stuff.

picture this: you're trying to get that golden hour shot, and it's just…grey. all the time.

let's break it down. i'm going to try to keep this somewhat organized, but honestly, it's a bit like trying to catch smoke.

*Spring (September - November): The Hopeful Mess

spring in santiago is supposed to be gorgeous. everyone raves about the cherry blossoms and the trees exploding with color. and yeah, it can be stunning. but it’s also a transition. you’ll get these bursts of sunshine followed by rain showers that feel like they’re straight out of a dramatic telenovela. it's really unpredictable. the air smells amazing - like wet earth and blossoms, but also occasionally like impending doom, you know?

*Temperature: Average highs around 18-22°C (64-72°F). Feels warmer when the sun actually decides to show up.
*What to Wear: Layers, layers, layers. Seriously. A light jacket, a sweater, a scarf. Think adaptable.
*Pro-Tip: Check the forecast multiple times a day. Don’t rely on that overly optimistic weather app.

Summer (December - February): The Dry Heat (Maybe)

summer is…deceptive. people say it’s hot and dry, and sometimes it is. other times, it’s just humid and overcast. you might get a few days of actual sunshine, but don't count on it. the peaks surrounding the city are surprisingly cool, a welcome escape from the city itself. i heard a local on r/Santiago on Reddit (seriously, check out that subreddit - it’s wild) say that summer's humidity is brutal. “It clings to you like a bad ex,” she said.

*Temperature: Average highs around 25-30°C (77-86°F). Can spike higher, but rarely stays that way for long.
*What to Wear: Light clothing, breathable fabrics. Sunscreen is a must.
*Drunk Advice: Don't plan an outdoor concert without a backup plan. Rain is always a possibility.

Autumn (March - May): The Golden Haze

autumn is probably the most “classic” santiago weather. it's mild, with crisp mornings and pleasant afternoons. the leaves on the trees turn all sorts of shades of brown and gold. it’s kind of magical.

It’s the perfect time for hiking in the nearby hills.

*Temperature: Average highs around 17-23°C (63-73°F).
*What to Wear: A light jacket or sweater is still a good idea. Comfortable walking shoes.
*Overheard Gossip: Someone at a cafe told me that autumn is prime picnic season. Apparently, the parks are packed!

Winter (June - August): The Gray Season of Gloom (and occasional sunshine)

winter is…well, it's grey. like, really grey. it’s not freezing cold, but it's damp and overcast for weeks on end. you might get a few days of sunshine, but they’re rare and precious. it's definitely the least popular time to visit. i spend a lot of time indoors during winter, editing photos and dreaming of sunny beaches somewhere far, far away.

*Temperature: Average highs around 13-17°C (55-63°F). Average lows around 5-9°C (41-48°F).
*What to Wear: A warm coat, gloves, a hat. Waterproof shoes are essential.
*Something a Local Warned Me About: Don’t expect endless sunshine. Bring a good book and embrace the cozy vibes.

Cost of Living (Rough Estimates - as of late 2023/early 2024)

Here’s a quick data table. Keep in mind these are just estimates and can fluctuate.

Seriously, rent can vary wildly* depending on the neighborhood. Proximity to the metro changes everything. you can find some pretty decent studios in communes like Ñuñoa or Providencia for around $600-$800, but don’t expect a palace.

So, yeah. santiago weather. it’s a challenge. but it's also part of what makes the city…well, santiago. just be prepared for anything and don’t expect a perfectly sunny vacation.

If you're planning a trip, check out TripAdvisor's Santiago page for more info. You can also get a feel for local events on Time Out Santiago. And seriously, the subreddit r/Santiago is a goldmine of info and opinions.
