Let me be honest: I packed for Iceland in October like I was heading to a moody photoshoot, not a trip where the wind would try to physically remove my jacket from my body. I brought a “waterproof” coat that turned out to be waterproof the way a paper towel is waterproof — technically, briefly, uselessly.
October in Iceland is this strange in-between season. The tourist crowds have thinned out, the Northern Lights start putting on their first real shows of the year, and the light does that gorgeous low, golden, slightly apocalyptic thing by 4pm. But the weather has zero interest in being predictable. You can get sideways rain, actual sunshine, and a wind gust that makes you question your balance — all before lunch.
This surprised me the most: it’s not really about the cold. Reykjavik in October sits somewhere around 4–9°C, which isn’t brutal. It’s the wind and the wet that get you. Most people overpack “cute” and underpack “functional,” and by day two they’re buying an overpriced fleece from a gift shop in Vík. Don’t be that person. Here’s what actually works.
Before We Dive In
Weather: October highs hover around 6–9°C (43–48°F), lows dip close to freezing, and daylight shrinks fast — from about 11 hours at the start of the month to under 8 by Halloween. Rain is frequent, but it’s the wind that defines the month, regularly gusting hard enough to turn a light drizzle into something that hits you sideways.
Walking conditions: Reykjavik’s streets are manageable, but the moment you’re near lava fields, black sand beaches, or waterfalls, you’re on wet rock, gravel, and boardwalks that get slick fast. Late October can bring the season’s first icy patches, especially on the Golden Circle route and near glacier viewpoints.
Style culture: Icelanders dress for function first, style second — and somehow still look put together doing it. Think a lot of black, navy, and oatmeal wool, technical outerwear worn without apology, and zero judgment for hiking boots at dinner. Nobody in Reykjavik is going to side-eye your puffer jacket. It’s basically the national uniform.
Your Bag: Carry-On or Duffle for the Ring Road
Here’s the thing nobody tells you: Iceland eats suitcases alive. Between gravel car parks, waterfall trails, and the occasional hotel with no elevator, a rigid hard-shell case becomes a liability fast.
A soft-structured duffle or a sturdy carry-on with all-terrain wheels handles Iceland’s terrain far better than anything glossy and rigid. If you’re road-tripping the Ring Road, a duffle that compresses down and squeezes into a trunk alongside cooler bags and camera gear is genuinely more useful than you’d think.
If you’re staying mostly in Reykjavik, a standard carry-on is fine — just don’t bring your nicest one.
Local tip: Pack a foldable tote or small daypack inside your main bag. You’ll want it for wet swimwear after the Blue Lagoon, muddy boots after a hike, or just separating “clean” from “questionable” on the way home.
Base Layers: Merino Wool Isn’t Optional, It’s Survival
I resisted merino wool for years because it sounded like something my outdoorsy uncle would recommend. He was right, and I’m annoyed about it.
A merino base layer — top and leggings — is the actual foundation of dressing for Iceland in October. It regulates temperature shockingly well, doesn’t hold odour the way synthetic layers do, and works whether you’re standing at a waterfall in driving wind or sitting in an overheated Reykjavik café five minutes later. Cotton, by contrast, is basically useless here. It gets damp from rain or sweat and just stays damp, which in a 7°C wind is miserable.
Wear it under jeans or hiking trousers during the day, and honestly, keep a set for sleeping too if you’re chasing the Northern Lights and standing outside at midnight.
Local tip: Buy merino a size true-to-fit, not loose. It works by sitting close to your skin — baggy defeats the purpose.
The Mid-Layer: Your Wool Sweater or Fleece
This is the piece that does the emotional heavy lifting of your outfit. A chunky wool sweater — ideally an actual Icelandic lopapeysa if you want a real souvenir that also functions as gear — or a good fleece goes over your base layer and under your shell.
The trick is thinking of your mid-layer as removable, not permanent. Iceland’s indoor spaces run warm, so you’ll be shedding this layer constantly — in restaurants, in the car, in museums — then putting it straight back on the second you step outside. Pack one that’s easy to stuff in a daypack without looking like a crumpled mess when you pull it back out.
Local tip: If you want the genuine lopapeysa experience, buy one from a small shop or the Handknitting Association of Iceland rather than a tourist trap near Laugavegur — the quality difference is obvious the moment you put it on.
Outer Shell: The Waterproof, Windproof Jacket That Actually Matters
I’ll say this bluntly: this is the one item worth spending real money on. Everything else can be a compromise. Your outer shell cannot.
You need something genuinely waterproof (not “water-resistant,” which is marketing for “fine in a light drizzle”) and windproof, ideally with a hood that cinches so it doesn’t blow off the second you’re near a waterfall.
A cute trench coat, a denim jacket, a fashion puffer with no hood — none of these will survive contact with actual Icelandic wind. I learned this the hard way standing at Skógafoss looking like I’d showered fully clothed.
If you run warm, a shell without heavy insulation over your wool mid-layer is more versatile than one all-in-one puffer, since you can adjust for how brutal the wind actually is that day.
Local tip: Test the hood cinch before you leave home. If it doesn’t tighten properly, your “waterproof jacket” is about to become a waterproof kite.
Bottoms: Jeans, Hiking Trousers, or Both
Regular jeans are fine for city days in Reykjavik — cafés, museums, the flea market — especially with thermal leggings underneath on colder days. But the second you’re doing waterfalls, glacier walks, or anything near black sand beaches, jeans become a problem. Wet denim is cold, heavy, and takes forever to dry.
For anything outdoorsy, pack one pair of water-resistant hiking trousers, ideally with some stretch. They layer over merino leggings beautifully and shrug off spray from waterfalls that would soak straight through denim. Shorts are, unsurprisingly, not really an October-in-Iceland thing — I wouldn’t bother.
Local tip: If you’re only bringing one non-jean bottom, make it something that layers over thermals, not something so fitted there’s no room underneath.
Footwear: Waterproof Hiking Boots, Non-Negotiable
This is where I see people make the biggest mistake — showing up with white sneakers because they photograph well. They will not photograph well covered in mud and lava grit, which is what happens within about twenty minutes.
You need a proper pair of waterproof hiking boots with real grip, broken in before you land (please don’t debut new boots on a glacier trail). Ankle support matters more than you’d expect, since a lot of Iceland’s most photogenic spots involve uneven volcanic rock, not paved paths. Save the stylish boots for dinner in Reykjavik — outside the city, function wins every time.
Local tip: Pack boots that are slightly roomier than your usual size to fit a thick wool sock without cutting off circulation. Cold toes ruin waterfalls faster than rain does.
Wool Socks: The Unglamorous MVP
Nobody wants to write a whole section about socks, but here we are, because bad sock choices quietly ruin more Iceland trips than bad jackets do.
Thin cotton socks get wet, stay wet, and turn your feet into ice blocks by hour two of any outdoor activity. Thick merino wool hiking socks solve this almost entirely — they insulate even when damp, which regular wool doesn’t always do. Pack more pairs than you think you need; damp socks from yesterday’s waterfall trip don’t dry overnight in a cool hotel room.
Local tip: Bring at least one dedicated pair just for travel days and flights — cold feet on a long drive around the Ring Road is a specific kind of miserable.
Hats, Gloves, and a Buff: Small Things, Huge Difference
The wind is the real villain of this trip, and it goes straight for your ears, hands, and neck. A proper beanie (not a thin fashion one — an actual insulated one) and a pair of waterproof or wool gloves are not optional accessories here, they’re basic equipment.
A buff or neck gaiter is the sleeper hit of Iceland packing. It blocks wind from sneaking down your collar, doubles as an extra ear layer, and takes up zero suitcase space. I didn’t bring one my first trip and spent an embarrassing amount of time with my sweater pulled up over my chin like a bandit.
Local tip: Touchscreen-compatible gloves save you from the ridiculous dance of pulling gloves off every time you want a photo — and in October, you will want a lot of photos.
The Swimsuit You’ll Almost Forget
It sounds counterintuitive to pack swimwear for a trip where you’re also packing thermal underwear, but the Blue Lagoon, Sky Lagoon, and countless local geothermal pools mean you’ll want it, probably more than once.
Pack a swimsuit you can actually move in, not something you’ll be adjusting the whole time — you’re getting in and out of near-freezing air repeatedly, and nobody needs that stress on top of it. Bring a quick-dry towel or one from your hotel, plus flip-flops for the walk between changing rooms and water, since bare feet on cold tile in October is its own small horror.
Local tip: Your hair will thank you if you skip conditioner before the Blue Lagoon — the mineral-rich water reacts badly with it and can leave hair feeling strawlike for days.
What NOT to Wear: The Mistakes I See Constantly
A few things I’d genuinely leave at home.
White sneakers, unless you enjoy the aesthetic of mud-splattered canvas.
A single lightweight rain jacket with no insulation layer underneath, since it’ll keep you dry and still cold.
An umbrella — truly, don’t bother, the wind will invert it within a block and you’ll be carrying a broken skeleton of metal for the rest of the day.
Also skip anything you’d be devastated to ruin. Iceland’s landscapes involve volcanic ash, mud, sulfur-smelling steam, and salt spray, and your clothes will know it by the end of the trip. This isn’t the place for your favourite cashmere.
Local tip: If you’re debating whether an item is “too outdoorsy” for the trip, it’s probably exactly right. Iceland does not reward vanity dressing.
Dressing for the Northern Lights Hunt
Chasing the aurora means standing still, outdoors, often near midnight, for anywhere from twenty minutes to two hours. This is a completely different packing challenge from daytime sightseeing, because you’re not moving enough to generate body heat.
Layer aggressively for this: merino base, wool mid-layer, insulated jacket, and genuinely warm accessories — this is where a proper insulated beanie and thick gloves earn their spot in your bag.
Thermal leggings under trousers are worth the slightly bulky look when you’re standing in a field at 11pm waiting for green light to show up. Bring hand warmers if you run cold; most Reykjavik pharmacies and outdoor shops sell them cheaply.
Local tip: Pack your warmest outfit as a dedicated “aurora kit” you can throw on quickly over whatever you’re already wearing, rather than trying to plan your whole day’s outfit around a maybe-tonight event.
Bags for the Day: Crossbody vs. Backpack
A small crossbody works fine for city days in Reykjavik, but the second you’re doing waterfalls, glacier walks, or anything with wind involved, it becomes annoying fast — swinging around, banging into your hip, getting in the way of a jacket zip.
A compact daypack is the better call for excursion days. You’ll want room for a water bottle, gloves you’ve just taken off, a buff, snacks, and your camera, and a backpack keeps your hands free for the inevitable moment you need to grip a railing against the wind.
Local tip: A pack with a rain cover, or at minimum a dry bag insert for your camera, is worth it — Icelandic weather doesn’t pause for your electronics.
Evening Outfits in Reykjavik
Reykjavik’s restaurant scene is more stylish than people expect, but it’s not fussy.
Smart-casual covers almost everywhere — think a nice sweater, dark trousers or jeans, and boots you don’t mind wearing indoors, since coat check isn’t really a thing at most casual spots.
If you’re going somewhere higher-end, a simple dress or button-down under your wool layers works, then you just shed the outer layer at the door.
The trick is building evening outfits around your daytime base rather than packing separate “going out” clothes. This is the same capsule logic that works for city trips further south — our capsule-style breakdown for Paris in September covers the same “layers that do double duty” approach, just swapped for Icelandic wool instead of a trench coat.
Local tip: Bring one slightly elevated top — a nicer sweater or blouse — that you can layer under your shell during the day and wear alone at dinner. One piece, two jobs.
Practical Packing: How Much to Actually Bring
You don’t need a different outfit for every day. Five or six tops, two or three bottoms, and a rotation of two jackets (your everyday shell and something warmer for aurora nights) will comfortably carry you through a week, because everything’s designed to layer and repeat rather than stand alone.
The real mistake is overpacking “outfits” instead of packing pieces that combine. Before you zip your bag, lay everything out and count how many combinations each item actually creates — if a piece only works with one other thing you’ve packed, it’s probably not earning its space. This is the exact logic behind a proper travel capsule wardrobe, and it applies just as much to Iceland’s wool-and-waterproofs kit as it does to a summer packing list for somewhere like Greece — different climate, same principle.
Pack laundry sheets or travel detergent if you’re staying more than five days; damp gear needs washing more often than you’d think, and drying racks in Icelandic guesthouses are more common than you’d expect.
So, Are You Ready?
Iceland in October isn’t a place that asks you to dress up. It asks you to dress smart — layers that work together, boots you trust on wet rock, a jacket that actually does what the tag promises. Once you get that right, something shifts. You stop thinking about the weather and start actually looking at the waterfall in front of you, the steam rising off a hot spring, the sky doing something green and unbelievable at 10pm.
Pack for function, leave the vanity pieces at home, and you’ll spend your trip genuinely comfortable instead of quietly miserable in a jacket that isn’t up to the job. That’s the whole secret. Go enjoy it.
