What to wear in Seoul in May? With highs of 73°F and lows of 56°F, May is warm, pleasant, and one of Seoul's most comfortable months for outdoor exploration — light layers and breathable fabrics handle the daytime easily, while a light jacket covers the still-cool evenings near the Han River. Nine days of rain mean occasional showers, so a compact umbrella or packable rain jacket belongs in every daypack. This is Korean public holiday season (Golden Week), so plan for crowded attractions.

Based on typical May conditions in Seoul. Weather varies year to year — check the live forecast when you're within two weeks of your trip.
May in Seoul offers some of the best weather of the year — warm enough for short sleeves by midday at Gyeongbokgung Palace, but still fresh enough in the mornings and evenings near Bukhansan to avoid the crushing humidity that arrives in July. The city is at its greenest, with full foliage along the Han River parks and lotus flowers beginning to bloom at Jogyesa Temple. Golden Week (early May) brings domestic travelers in large numbers, filling the palaces and Insadong alleys. Seoul's fashion-forward neighborhoods like Garosu-gil and Hongdae showcase their spring collections in May — lightweight linen shirts, silk-blend blouses, and cropped trousers over stylish sneakers or loafers are the local standard. A light bomber jacket or denim jacket worn open over a t-shirt handles the full day-to-evening temperature range. The humidity is still manageable in May, unlike the drenching July monsoon season.
A black blazer over an ivory blouse and pleated maxi skirt in warm rain is complete formal coverage. Black mule heels are the practical formal choice when espadrilles are off the table.
A black longline parka over a crewneck sweatshirt in warm rain has a deliberateness that works. Ivory satin mules and a cream beanie are the contrasts that make it.
A black rain jacket over ivory linen trousers refuses to look sloppy in warm rain. Espadrilles and a crochet bucket hat keep the warm-weather mood alive below the waterline.
A light wash denim jacket over a denim mini skirt makes a strong case for double denim in warm rain. The black square neck top underneath adds structure.
A blush cropped jacket over a white linen blouse and ivory wide-leg trousers refuses to look heavy in warm rain. Tortoiseshell cat-eye sunglasses are the editorial punctuation.
A white linen blazer over matching wide-leg linen trousers and a blue collarless blouse stays entirely polished through warm rain. Slide sandals and gold aviators make it feel like summer despite the drizzle.
A yellow hooded rain jacket over biker shorts and a longline tee handles warm rain with high-visibility attitude. Ivory pointed-toe mules are the surprising finishing note.
Wear light, breathable layers in May: a t-shirt or light long-sleeve as a base, a thin jacket or cardigan for morning and evening, and comfortable walking shoes. Midday at Bukchon Hanok Village can feel warm in the low 70s if the sun is strong, but evenings by the Han River require a jacket. Avoid heavy denim or wool — opt for cotton, linen, or moisture-wicking synthetics.
May is one of Seoul's best months for visitors — excellent weather, full spring foliage along the Han River, and major cultural events like the Lotus Lantern Festival near Jogyesa Temple. The main drawback is Golden Week (early May) when domestic tourism peaks sharply; book palace tickets and popular restaurants well in advance. Late May offers the same good weather with slightly thinner crowds.
Clean sneakers, leather loafers, or light canvas shoes are ideal for May's warm, mostly dry weather. Comfortable walking shoes with good support are essential given Seoul's extensive pedestrian culture — a full day of exploring Myeongdong, Insadong, and the Han River parks can easily cover 8–10 miles on foot. Keep one pair of water-resistant shoes handy for the 9 likely rain days.
May averages a high of 73°F (23°C) and a low of 56°F (13°C). It's genuinely warm by day — short sleeves are comfortable in direct sun — but evenings near Bukhansan and the Han River maintain a pleasant cool that requires a light layer. Humidity begins to creep upward compared to April but remains comfortable. About 9 days see some rain, usually as afternoon showers rather than all-day events.
Pack t-shirts or light long-sleeves, one or two warmer layers (a denim or bomber jacket), breathable trousers or shorts for warm afternoons, and comfortable walking shoes. A packable rain jacket or compact umbrella handles the occasional shower. Sun protection matters more in May than the winter months — sunscreen and a light hat for outdoor palaces and Han River walks are recommended.
