The main advantages are: - Comfortable spring temperatures - Lower humidity than summer - Green mountains, parks, and palace grounds - Strong conditions for walking-heavy city itineraries - Seasonal atmosphere without peak summer discomfort ## What the weather feels like You do not need winter gear, but mornings and evenings can still feel cooler than many visitors expect. - **Seoul:** Mild afternoons, cooler mornings and nights - **Busan:** Slightly softer coastal weather - **Jeju:** Mild and breezier - **Mountain areas:** Noticeably cooler early and late in the day For most travelers, the right packing logic is simple: T-shirts or light long sleeves, one knit layer, one light jacket, comfortable walking shoes, and a compact umbrella. ## What to wear in Korea in May The best approach is light layering. - **Good choices:** T-shirts, light knits, overshirts, a thin jacket, jeans or trousers - **Useful backup:** Compact umbrella and a bag-friendly extra layer - **Skip:** Heavy winter coats and thick thermal clothing If you are planning a temple stay, add conservative clothing and socks. ## Crowds and booking pressure The busiest periods in **May 2026** are likely to be: - **Saturday, May 2 to Tuesday, May 5, 2026** around Children's Day - **Friday, May 22 to Monday, May 25, 2026** around Buddha's Birthday and the substitute day off You will feel pressure most in: - Family attractions in Seoul - KTX trains - Popular temple stays - Well-located hotels in Seoul, Busan, and Jeju - Domestic flights and rental cars on Jeju routes If you want flexible hotel inventory, use [Seoul hotels on Booking.com](https://www.booking.com/city/kr/seoul.html?aid=2825454).

Use the dedicated [Children's Day Korea 2026](/childrens-day-korea-2026/) guide if you are planning around that exact holiday. ### Mid-May Usually the easiest part of the month if you want good weather with slightly less friction. ### Late May Better for lantern-season atmosphere, temple visits, and culture-focused travel.

Keep one extra layer with you Sunny afternoons can still become cool evenings. ### 2. Do not build an outdoor-only itinerary May is favorable, not guaranteed. One indoor backup each day is still smart. ### 3. Book high-demand items early That includes temple stays, family hotels, Jeju transport, and holiday-adjacent KTX seats. ### 4. Treat holiday weekends differently Ordinary midweek May travel is much easier than the two heavy domestic windows. ### 5. Use specific guides for holiday periods This page should stay focused on month-level planning. Use the dedicated Children's Day and Buddha's Birthday pages for event details. ## FAQ ### Is May the best month to visit Korea?
