#Weather in Seoul in May

Figures are Korea Meteorological Administration 1991–2020 normals for Seoul.
What that actually means for your trip:
- This is Seoul's most comfortable month. Highs in the mid-20s, mild nights, and none of the humidity of summer yet.
- The rain comes as showers. A little more than April, about 104mm over seven wet days, but rarely long grey spells.
- The dust eases. Yellow dust is less common as the month goes on, and the skies clear.
- The evenings are long and warm enough to stay outside until late, with sunset approaching eight by the end of the month.
Is May a good time to visit Seoul? Yes; for many people it is the best month of the year: warm, green, mostly dry, and full of festivals, above all the Lotus Lantern parade and Buddha's Birthday. The catch is demand: the first week, when Korea's holidays coincide with China's and Japan's, is the busiest of the spring, so book rooms early, or come in the second half of the month.
#May in the city
The Lotus Lantern Festival, Yeondeunghoe, is on UNESCO's list of intangible cultural heritage, and its lantern parade is one of the great nights of the Seoul year.
In 2027 it runs on Saturday 8 May from 7pm to 9:30pm, carrying thousands of lanterns along Jongno towards Jogyesa temple; the next day, Sunday 9 May, a traditional culture street festival runs around the temple from 11am. All of it is free. See our Lotus Lantern Festival guide.
Buddha's Birthday is Thursday 13 May 2027, a public holiday: temples hold ceremonies, and many offer visitors a free bowl of bibimbap at lunchtime.
The holidays come thick and fast: Labour Day, a public holiday since 2026, falls on Saturday 1 May, so Monday 3 May is a substitute holiday; Children's Day is Wednesday 5 May; and Jongmyo Jerye, the royal ancestral rite at Jongmyo Shrine, is usually held on the first Sunday of May, which would be 2 May in 2027, with court music and costumes handed down for centuries.
#What to Do in Seoul in May
Solo Travellers
Join the lantern parade crowd on 8 May, visit Jogyesa and Bongeunsa on Buddha's Birthday, and see the royal rite at Jongmyo Shrine on the first Sunday of the month, one of the few chances to see the shrine used as it was built to be.
Couples
Spend a warm evening by the Han at Banpo, where the fountain on the bridge runs on spring and summer evenings, and walk the lanes of Seochon for dinner.
Families
Join in at the Children's Day events on 5 May if you are travelling with children, and on another day take the cable car up Namsan and walk down through the park.
Groups
Hike Bukhansan on a clear weekday, when the green is at its freshest, or take the riverside night markets at Yeouido and Banpo, with food trucks and craft stalls, on a Friday or Saturday night.
#Getting Around
Trains on the AREX line run from Incheon Airport to Seoul Station, the express in 43 minutes from Terminal 1; for everything else, a T-money card covers the subway, buses and most taxis.
On the evening of the lantern parade, roads in Jongno close and the stations around Jonggak and Anguk are crowded from late afternoon. The first-week holidays in China and Japan also fill the airport trains and Myeongdong.
#Budget & Costs
| Travel style | Per day | What it covers |
|---|---|---|
| Budget | ₩85,000–140,000 | Guesthouse, markets, the subway |
| Mid-range | ₩220,000–350,000 | A central hotel, restaurants, palace tickets |
| Luxury | ₩580,000+ | Five-star rooms, fine dining, a private guide |
May is high season: rooms are dear through the first week, when China's and Japan's holidays coincide with Korea's own, and again around the lantern weekend.
Costs worth knowing:
| What | Price |
|---|---|
| Lotus Lantern parade and street festival | Free |
| Temple bibimbap on Buddha's Birthday | Free at many temples |
| Jongmyo Jerye | Free to watch, with limited seating |
| Palace entry | ₩3,000, free in hanbok |
| A bunch of carnations | A few thousand won |
- Book rooms early for the first week and the lantern weekend.
- Come after the 15th for calmer, cheaper days.
- Check the K-ETA rules for 2027 before you travel.
#Food & Dining
May is the start of the cold-noodle season, and naengmyeon restaurants get busy as the temperature climbs.
Chamoe, the small yellow Korean melon, is in every market, and the last spring greens are still around.
On Buddha's Birthday, the temple bibimbap is the meal; for the rest of the month, Gwangjang Market's stalls are at their most pleasant before the summer heat.
#Nightlife
May evenings are made for being outside. The riverside parks stay busy until late, the pavement bars of Euljiro and Jongno put their tables out, and the city's weekend night markets along the Han run through the warmer months; check the schedule, as they move between locations.
#Shopping
Carnations are everywhere in early May: Parents' Day, 8 May, is when children give them to their parents, and Teachers' Day, 15 May, follows.
The flower market at the Express Bus Terminal is busy before both, and Insadong sells lanterns and Buddhist crafts in the weeks before Buddha's Birthday.
#Culture & Etiquette
- At a temple, walk around the main hall clockwise, keep your voice low near worshippers, and do not step on the thresholds.
- On the parade route, do not grab at the lanterns, which volunteers carry.
- Cover shoulders and knees for temple visits.
- Join the queue for temple bibimbap; visitors are welcome.
#Essential Local Phrases
| Korean | Meaning | When to use |
|---|---|---|
| 연등회 (yeondeunghoe) | Lotus Lantern Festival | On every poster in Jongno |
| 부처님오신날 (bucheonim osinnal) | Buddha's Birthday | The 13 May holiday |

| 카네이션 (kaneisyeon) | Carnation | For Parents' Day |
| 참외 (chamoe) | Korean melon | Market stalls from May |

#Packing List
- Light clothes for warm days and a layer for evenings
- A compact umbrella for showers
- Comfortable shoes for a long lantern night
- Sunscreen and a hat
- A small cushion or mat for the parade route
- Shoulder and knee cover for temples
- A power bank
#Backup Plans
If it rains: the National Museum of Korea, the National Palace Museum beside Gyeongbokgung, which explains the court whose rites you may see at Jongmyo, and the Seoul Museum of History.
If the first week is too crowded: leave the famous sights to the second half of the month, and spend the holidays on the hills or by the river.
If the parade route is packed: watch from a side street, or go to Jogyesa for the street festival the next day.
#Safety & Health
May is one of the healthiest months to visit Seoul: comfortable temperatures, lower dust and no monsoon yet. The main risk is the crowd on the lantern parade route, where it is easy to lose people in the dark: agree a meeting point. The sun is strong by late May.
Emergency: 119 for fire and ambulance, 112 for police, and 1330 for the travel hotline.
