Korea in October and November: Weather, Fashion & What to Pack
Two months. Two very different sides of Korea. One beautiful season.
If you are planning a trip to Korea in October or November, you are visiting during one of the most beautiful transitions of the year.
October is crisp, colourful and comfortable, with autumn foliage beginning to transform mountains, parks and city streets. November starts with the last beautiful weeks of autumn in many parts of Korea, but gradually becomes much colder as winter approaches.
This also means that Korea weather in October and November can feel very different, even within the same trip.
You might leave your hotel in a light sweater one morning and reach for a proper coat a few weeks later.
So, what should you pack for Korea?
What should you wear in October?
And how cold is Korea in November?
Here is a practical guide to Korea in October and November, including weather, fashion, packing tips and what to do if you realise you need something warmer after you arrive.
October: The Month Korea Shows Off
October in Korea feels like the country has been saving its best self for this moment.
The summer heat and humidity are completely gone. The skies are clear and reliably blue in a way that makes every outdoor photograph look effortless. Daytime temperatures sit around 18°C to 22°C in early October, warm enough to walk around comfortably in a light top, cool enough that you are not exhausted by noon. And by late October, when temperatures drop to around 12°C to 18°C, the foliage begins to peak. The mountains turn red and gold. The ginkgo trees lining Seoul's major boulevards go a deep, glowing yellow. Palace courtyards become the most beautiful versions of themselves.
It is, genuinely, one of the best times of year to be in Korea.
The trade-off is that other people know this too. October is popular, domestic Korean tourism increases significantly, and popular foliage destinations like Seoraksan and Nami Island can get very busy on weekends. If your schedule allows it, visiting on a weekday makes a real difference.
What to Wear in October
Early October is relatively forgiving. A light jacket thrown over a T-shirt will cover most of what the weather asks of you. By late October, you will want a proper mid-layer, a sweater or knit and a coat that you actually like wearing, because you will be in it a lot.
A practical early October wardrobe looks something like this:
• Light tops: T-shirts are still perfectly comfortable during sunny afternoons
• Jeans or casual trousers
• A cardigan or light hoodie for mornings and evenings
• A light jacket: not always needed at midday, but you will want it by evening
• Comfortable walking shoes: foliage season means spending a lot of time outside
• A compact umbrella: brief showers can arrive without much warning
By late October, shift toward:
• Layered outfits: a thin knit underneath, a sweater or mid-layer on top
• A mid-weight jacket or coat: evenings genuinely need it
• A scarf: both useful and very much in season
• Ankle boots or closed-toe shoes
October is when Korean street fashion is at its most beautiful. Earth tones dominate, camel, beige, rust, olive, charcoal. Long coats appear early, often over simple outfits that let the coat do the talking. Scarves are worn as much for style as for warmth. If you enjoy fashion, October in Seoul is a wonderful month to simply pay attention to what people around you are wearing.
November: Beautiful, Then Cold
I want to be honest with you about November, because it is a month that can catch people off guard.
The first half of November is still genuinely lovely. Many foliage destinations are at or near their peak, Naejangsan, Bulguksa Temple in Gyeongju, Jirisan, and daytime temperatures of around 8°C to 13°C are cool but manageable if you are properly dressed. The crowds thin compared to October, which a lot of travellers actually prefer. There is something quieter and more intimate about Korea in early November.
The second half of November is a different story. Temperatures drop to around 3°C to 8°C. Winds pick up. By the end of the month, Seoul can see its first light snow, and the mountains have already had theirs. Winter has arrived. A proper warm coat is no longer optional at this point, it is the most important thing in your suitcase.
What to Wear in November
For early November, you need:
• A warm sweater or knit as your main layer
• A medium-weight coat
• Jeans or thicker trousers
• A scarf: essential now, not optional
• Closed-toe shoes or ankle boots
• A compact umbrella
For late November, the list changes considerably:
• Thermal inner layers: Uniqlo's HEATTECH range is enormously popular with both locals and visitors, lightweight and genuinely warm
• A warm sweater or fleece as your mid-layer
• A proper winter coat: lighter puffer jackets layered over sweaters are the classic local look by this point
• Scarf, gloves and a warm hat
• Warm boots
November air in Korea is dry as well as cold, the humidity drops significantly from October onward, and this catches a lot of first-time visitors by surprise. Pack a good moisturiser and lip balm. Your skin will thank you.
By November, many Korean cafés, guesthouses and restaurants will have their ondol, the traditional underfloor heating, running, which means you may be asked to remove your shoes more frequently. Shoes that slip on and off easily will save you more frustration than you might expect across a multi-day trip.
Does It Matter Where in Korea You Are?
More than you might think, yes.
If you are heading to the south, Busan, Geoje or the coastal towns, you will find noticeably milder temperatures than in Seoul, especially in October. The sea moderates the climate, and evenings feel much more comfortable than further north. Jeju Island is similar: warm enough in October that you might still reach for short sleeves on a sunny afternoon, and cooler but manageable into early November.
At the other end, mountainous areas in Gangwon Province, around Seoraksan, Pyeongchang, Taebaek, are considerably cooler than Seoul throughout autumn. If you are hiking in October, bring an extra layer even if the city forecast looks warm. In November, mountain conditions can feel properly wintry well before the cities do.
Seoul itself sits in the middle, comfortable in early October, increasingly cold through November, and noticeably windier near the Han River and open spaces than in more sheltered neighbourhoods.
If You Underpack, It Happens
Here is something reassuring: Korea is one of the easiest countries in the world to buy things you forgot, or did not realise you would need.
If you need warm layers, Uniqlo has HEATTECH thermals, light puffer jackets and warm basics at very reasonable prices. SPAO and TOPTEN10 are popular Korean alternatives if you want something that feels a little more local. For smaller things, gloves, a compact umbrella, hand warmers, Daiso has most of what you need at very low prices. And if the dry autumn air is affecting your skin, Olive Young is the easiest place to find Korean skincare and moisturisers.
Convenience stores like GS25 and CU are open late or around the clock, and are worth checking first if you need something quickly, umbrellas, basic toiletries and hand warmers are usually available.
There is genuinely no need to overpack out of anxiety. Korea has you covered.
One Last Thing
I have been learning about Korea for years now, through the language, the culture, the food, the history, the small daily details that make it feel so particular and so warm. And one of the things I keep coming back to is how Korea rewards the people who slow down a little.
October and November are good months for slowing down. The weather invites it. A warm café when the air outside is cold. A long walk through a palace courtyard when the trees are red. An afternoon that was meant to be one hour and became three because you found a street you did not want to leave.
Dress for the weather. Pack layers. Leave a little room in your bag.
And let Korea do the rest!
