Packing clothes for Korea: follow the forecast, not the month
Seoul and Busan feel different even in the same month. Pack by the forecasted high and low, not the calendar — layers you can shed easily.
Packing clothes for Korea: follow the forecast, not the month
A Seoul morning, a Busan afternoon and an air-conditioned train can demand different layers on the same trip. Start with the forecast low and high for your destination, then pack two or three removable layers. This guide's source review date was September 13, 2026. Check the medium-range forecast about seven days out, and the short-range forecast and warnings the day before.[3][4][5]
Monthly normals as a starting point
These rounded 1991–2020 climate normals give monthly average daily low–high temperatures in °C and monthly precipitation in mm. They are not a forecast for any individual day.[1][2]

Busan's winter mornings are generally milder than Seoul's, but coastal wind may feel colder. Seoul has frequent subzero winter conditions and heavy summer monthly rainfall. On Jeju and other coasts, wind and rain matter; in mountains, elevation and shade change the picture. Use a forecast for the actual locality.
Build an outfit from both ends of the forecast
Below freezing, combine a thermal base and knit with a down or insulated wind-blocking coat, warm trousers, waterproof shoes with grip and thick socks. Gloves, scarf, hat and lip balm fit the same bag. At 0–5°C, wear a warm base, long sleeve and knit under a heavy coat or light puffer plus wind layer; choose grippy trainers, trousers, gloves and a folding umbrella. At 6–10°C, a long sleeve and thin knit under a trench, jacket or light puffer work with trousers, cushioned trainers, scarf and umbrella.
At 11–15°C, a long-sleeved shirt, cardigan or thin jacket, trousers and walking shoes usually offer flexibility; add an umbrella. At 16–20°C, use a short or long sleeve, light shirt or cardigan, light trousers, breathable trainers, sun hat and small umbrella. At 21–25°C, choose a breathable tee, thin trousers or long skirt, ventilated shoes and spare socks, with a light layer for strong indoor cooling, water and umbrella. From 26°C upward, quick-dry tees and airy bottoms plus shoes or sandals that dry quickly suit wet days; keep water, hat, umbrella, spare top and a thin indoor layer.
Spring: a cool return after sunset
*The source describes visitors in long trousers and light hoodies or jackets on Yeouido's blossom path. The photograph cannot establish that day's temperature.*
March may still call for winter pieces; April for a light jacket, while a May afternoon may suit a tee. For one walking day, try a long sleeve, thin knit, wind-resistant jacket, trousers, trainers and folding umbrella. Check KMA dust and yellow-dust information and pack a mask according to personal need.
Summer: make room for dry replacements
*The source dates this Haeundae Beach picture to October 27, 2006. Distant people are too small to judge clothing; it is not evidence of summer attire.*
Two quick-dry tops, an airy bottom, fast-drying shoes and spare socks make rain less disruptive. Add a thin long sleeve for cold trains and cafés, umbrella and waterproof pouch. Heavy-rain, heat or typhoon warnings call for less time outdoors and attention to official instructions.[5]
Autumn: space for the jacket you take off
*The source labels this late-autumn fallen leaves at Seoul's Dosan Memorial Park. No outfit is visible, so use it only for seasonal context.*
Early September can still feel like summer; October rewards layers, and November may need a coat or light puffer. Pack a tee or long sleeve, shirt, thin jacket, trousers, trainers and a light scarf. A bag for the discarded daytime layer is more useful than committing to one heavy item.
Winter: grip matters as much as insulation
*The source describes snow at Gyeongbokgung with distant visitors in warm coats. Shoes with traction help after snowfall.*
Thermals, knit, wind-blocking down or coat, warm trousers, gloves, scarf and waterproof grippy shoes make a practical starting kit. Avoid smooth soles on snow or ice and shorten your stride. Lip balm and a small moisturizer may help in dry heated rooms.
For a long walking day, prefer already broken-in cushioned trainers to new shoes and change socks before blisters develop. Carry a thin middle layer against both summer cooling and winter heating. Children and older travelers may benefit from another adjustable layer and routes with water, rest and indoor shelter. This is general preparation, not individual medical advice.
Before leaving, use both the expected low and high, and switch to a location-specific forecast for Jeju, coast or mountains. For the arrival journey see the Incheon Airport–Seoul transport guide.[6]
