What to wear in Seoul in March? Temperatures climb to a high of 52°F and a low of 35°F as spring begins to push back the winter — daytime is comfortable in a medium-weight coat, but mornings and evenings near Bukhansan or the Han River still demand warm layers. With 7 days of precipitation, light rain showers become more frequent than snow, so a water-resistant layer replaces the heavy parka for most outings. Layering is the essential March strategy.
March in Seoul is one of the most dynamic months for weather — warm sunny afternoons can suddenly yield to cold, wet evenings as winter and spring wrestle for control. The city comes alive with the first plum blossoms near Bukchon Hanok Village and the early cherry trees beginning to bud by month's end. Visitors to Insadong and Gyeongbokgung will enjoy pleasant midday temperatures, but the 35°F low means a warm layer is always needed once the sun drops. Seoul's streetwear scene fully shifts gears in March — the heavyweight puffers give way to structured wool coats, oversized knit cardigans, and transitional trench coats layered over thermal shirts. The key is packing pieces that work both at 35°F and 52°F: a removable mid-layer under a medium-weight water-resistant coat covers the full daily range without requiring a wardrobe change.

Packing List
What to Pack for Seoul in March →
Wear a medium-weight coat (wool blend, trench coat, or a lighter down jacket) over a warm mid-layer like a knit sweater or thermal long-sleeve. Mornings near Bukhansan or along the Han River remain cold enough for gloves and a light scarf. Keep layers removable — midday temperatures near Myeongdong can feel comfortable in just a sweater if the sun is out. Water-resistant footwear handles the increased rain frequency.
March is an excellent time to visit Seoul for shoulder-season value and the start of cherry blossom season. Late March sometimes delivers the first cherry blossoms at Yeouido Park and along the Han River — among the most photographed scenes in Korea. Crowds are lighter than April's peak blossom season, and hotel rates are more moderate. Weather is variable but very manageable with a layered wardrobe.
Waterproof ankle boots or clean sneakers with good water resistance work well in March. Snow becomes rare after mid-month, but rain increases — non-slip, waterproof footwear handles the wet cobblestones of Bukchon Hanok Village and the granite steps of mountain trailheads. If you plan to hike Bukhansan, trail runners with waterproofing or light hiking boots remain appropriate through March.
March averages a high of 52°F (11°C) and a low of 35°F (2°C). The first half of March still feels distinctly wintry, particularly in the mornings, while the second half brings genuinely spring-like afternoons. Precipitation rises slightly to about 7 days, transitioning from occasional snow to more frequent light rain. Wind chill near the Han River remains significant on overcast days.
Pack a medium-weight coat (wool, trench, or light down), 2–3 warm mid-layers (knit sweaters or thermal shirts), slim trousers or jeans, and water-resistant ankle boots. Bring a compact umbrella for spring showers and a light scarf and gloves for chilly mornings. You can leave the heaviest thermals at home but keep a lightweight thermal layer for cold evenings on the Han River or Bukhansan trails.
