What to Wear in Korea: Monthly and Temperature Guide
Use Seoul and Busan monthly normals, seven temperature cards and four seasonal capsules to pack practical layers.
What to wear in Korea: a month-by-month, temperature-led packing guide
In Korea, morning, afternoon and heated or air-conditioned interiors can feel very different. Seoul and Busan also diverge. Start with the forecast temperature band, not the calendar, and pack two or three removable layers. Researched 13 September 2026.
Check the medium-range forecast seven days before departure, then the short-range forecast and warnings the day before. Normals guide packing; they do not guarantee weather.[3][4][5]
Monthly normal ranges: Seoul and Busan
These are rounded 1991–2020 climate normals: monthly mean daily low–high and monthly precipitation for packing, not a forecast or a promise for any day.[1][2]

Busan winter mornings are generally milder than Seoul's, but coastal wind can feel colder. Seoul often falls below freezing in midwinter and summer precipitation rises sharply. Jeju and coasts can be windier and wetter; mountains can be colder and changeable. Use the forecast for your exact point.

March may still need winter pieces; April often suits a light jacket; May afternoons may suit a T-shirt. Evenings can be cool. Check official air-quality and dust information and carry a mask if it suits your needs.
One-day spring capsule: long-sleeve tee + light knit + windproof jacket + trousers + trainers + compact umbrella.
Summer: monsoon rain, heat and typhoons

Pack quick-dry tops and spare socks plus a thin layer for strongly air-conditioned trains and cafés. Fast-drying footwear and a waterproof pouch are often more useful than relying on an umbrella alone. Reduce outdoor plans and follow official instructions during heavy-rain, heat or typhoon warnings.[5]
One-day summer capsule: two quick-dry tees + thin long sleeve + airy bottoms + quick-dry footwear + spare socks + umbrella/waterproof pouch.
Autumn: bright afternoons, cool evenings

Early September can still feel summery, October rewards layers, and November may need a coat or light down. Bring a bag that can hold the layer you remove at midday.
One-day autumn capsule: short- or long-sleeve top + overshirt + light jacket + trousers + trainers + light scarf.
Winter: cold waves, dry air, snow and ice
Caption: Snow-covered Gyeongbokgung in Seoul, with distant visitors in insulating coats. Shoes with grip can help after snow.
Combine a windproof outer layer, thermal base and gloves/scarf. Lip balm and a small moisturiser can be useful in dry heated rooms. Avoid smooth soles on snow or ice and shorten your stride.
One-day winter capsule: thermal base + knit + down/coat + warm trousers + water-resistant grippy shoes + gloves/scarf.
Long walking days and indoor climate
• Choose broken-in cushioned shoes and change socks before friction becomes a blister.
• Carry one thin middle layer for both summer air conditioning and winter heating.
• For children and older travellers, add one easy-to-remove light layer and plan regular rest, drinks and easy indoor stops. This is general preparation, not personal medical advice.
Final pre-departure check
1. Check the destination's medium-range forecast seven days out.[4]
2. Check hourly short-range details and warnings the day before.[3][5]
3. Pack for both the forecast minimum and maximum bands.
4. Replace city assumptions with the exact Jeju, mountain or coastal forecast.
5. For a Seoul arrival plan, see the Incheon Airport–Seoul transport guide.[6]
