Seoul in April — Travel Guide
By Harry Nara · Last updated
Seoul in April offers some of the best conditions of the year, ideal for cherry blossom, photographers & walkers. Expect temperatures of 8–18°C, around 7 days of rain, and very high crowds across the city. Daily budgets typically land around ₩90,000–150,000 for mid-range travellers. Book accommodation two to three months ahead — the most popular rooms sell out fast during peak visiting windows.

#Weather in Seoul in April

Figures are Korea Meteorological Administration 1991–2020 normals for Seoul.
What that actually means for your trip:
- The city turns pink, then green, in about three weeks. The blossom passes quickly, and by the end of the month the trees are in full leaf.
- The mornings are cold, the afternoons warm. Single figures at breakfast and the high teens by mid-afternoon are normal, so dress in layers.
- This is the heart of the yellow dust season. Most days are clear, but a dusty day turns the sky beige and the air gritty.
- The evenings get long enough for a walk by the river after dinner, with sunset moving past seven.
Is April a good time to visit Seoul? It is the month Seoul is sold on, and for good reason. The blossom along the Han, around the lakes and in the palace gardens is spectacular, and the weather is mild. The questions are timing and crowds: the peak has moved earlier in recent years, so watch the forecast, and come on weekdays if you can. Book rooms early, as the blossom weekends are among the most expensive of the year.
#April in the city
The cherry blossom is the event, and its timing is the question. The weather agency times the season by one tree in Jongno: its long-run opening date, over 1991–2020, is 8 April, with full bloom two days later, and in 2026 it opened on 29 March. Expect the peak between the last days of March and mid-April, and watch the forecast in the weeks before you travel.
Yunjung-ro, the road that circles behind the National Assembly on Yeouido, is lined with well over a thousand old cherry trees and is closed to traffic for the blossom festival in most years, and Seokchon Lake in Songpa, with Lotte World Tower behind, is the other classic.
The lanterns go up through April at temples across the city, ahead of Buddha's Birthday on 13 May, and by the end of the month Jogyesa in Jongno is roofed in coloured lanterns.
#What to Do in Seoul in April
Solo Travellers
Ride a public bike along the south bank of the Han between Yeouido and Banpo under the blossom, then retreat to the free halls of the National Museum of Korea, calm when the parks are packed.
Couples
Book Gyeongbokgung's spring night opening, sold online, or simply walk into Changgyeonggung, which stays open until 9pm (last entry 8pm, closed Mondays) with no booking, and see the lit courtyards under the blossom at dusk. A picnic by the Han after dark, with the trees lit along the bank, is the other April date.
Families
Seoul Forest and Children's Grand Park have lawns and blossom without the crush of Yeouido, and bike hire at the Hangang parks makes an easy afternoon. Bring masks for a dusty day.
Groups
Take a day trip to Jinhae, the naval port on the south coast with Korea's biggest blossom festival and around 360,000 trees, on a weekday; it is several hours away by train and bus and usually blooms a few days before Seoul.
#Getting Around
Incheon Airport is linked to the city by AREX trains, nonstop to Seoul Station in 43 minutes from Terminal 1. Around town, one T-money card pays for the subway and buses, and changing between them within half an hour costs little extra.
The blossom routes are where April transport breaks down: on peak weekends, Yeouinaru and National Assembly stations, closest to Yunjung-ro, and Jamsil for Seokchon Lake are crushed from late morning.
Cycling the Han riverside paths on Ttareungi, the public bikes, is the pleasant alternative.
#Budget & Costs
| Travel style | Per day | What it covers |
|---|---|---|
| Budget | ₩85,000–140,000 | Guesthouse, markets and picnics, the subway |
| Mid-range | ₩220,000–350,000 | Hotel near a blossom spot, dinners out, a night palace ticket |
| Luxury | ₩580,000+ | A river-view luxury hotel, fine dining, a guide |
April is one of the most expensive months for a Seoul room, especially over the peak blossom weekends. The blossom itself is free, and a riverside picnic costs less than a restaurant lunch.
Costs worth knowing:
| What | Price |
|---|---|
| Palace entry | ₩3,000, free in hanbok |
| Palace night opening | Booked online, limited places |
| Hanbok rental | Priced by the hour or the day |
| National Museum of Korea | Free permanent galleries |
| A picnic mat at a riverside shop | A few thousand won |
- Book the room early for the blossom weekends.
- Come on weekdays for the famous spots.
- Check the K-ETA rules for 2027 before you travel.
#Food & Dining
April is the season for ssukguk, a clear soup with young mugwort, and for jjukkumi, the small octopus at its best in spring, stir-fried with chilli. Spring greens fill the side dishes, and the first chamoe, Korean melons, appear by the end of the month.
A blossom picnic is the April meal: gimbap from a convenience store or Gwangjang Market, and a mat on the grass by the river.
#Nightlife
The riverside parks fill in the evenings, and a picnic with beer by the Han after dark is the most April thing to do in Seoul. Yeouido's festival and the lit trees at Seokchon Lake draw evening crowds; afterwards, the bars of Songnidan-gil and Seongsu are close.
#Shopping
Spring collections are in the shops, and Seongsu's pop-up stores change frequently. The outdoor-gear shops near the mountains are busy as the hiking season starts, and the hanbok rental shops around Gyeongbokgung are booked out on blossom weekends.
#Culture & Etiquette
- Keep moving on the narrow blossom paths, where thousands are photographing each other.
- Picnics are welcome on the riverbanks; take your rubbish home or sort it at the bins.
- Wear a mask on a high-dust day if you have asthma; many Koreans will.
- Give way to the bikes on the riverside paths.
#Essential Local Phrases
| Korean | Meaning | When to use |
|---|---|---|
| 벚꽃 축제 (beotkkot chukje) | Cherry blossom festival | On posters across the city |
| 만개 (mangae) | Full bloom | On the forecast when it counts |
| 사진 찍어 주시겠어요? (sajin jjigeo jusigesseoyo?) | Could you take a photo? | Under the trees |
| 돗자리 (dotjari) | Picnic mat | At a riverside convenience store |
| 공기 나빠요 (gonggi nappayo) | The air is bad | Small talk on a dusty day |
| 꽃구경 (kkotgugyeong) | Flower viewing | Every weekend plan this month |
#Packing List
- A light jacket for cold mornings
- Layers for days that range ten degrees
- A few KF94 masks for yellow-dust days
- A light waterproof
- Comfortable shoes for long blossom walks
- Sunglasses and sunscreen
- A power bank for a day of photographs
#Backup Plans
If the dust is high: stay inside, with the Leeum's ceramics, the vast free galleries in Yongsan, or the underground malls of COEX.
If the blossom has passed before you arrive: look up: the trees on the hills, along the Seoul City Wall and at Namsan often flower a few days later than those by the river.
If it rains: take a long lunch in Gwangjang Market, which is covered.
#Safety & Health
Dust is April's health question: on a high reading, anyone with asthma or a heart condition should avoid hard exercise outdoors, and a KF94 mask helps. On peak weekends the paths on Yeouido and around Seokchon Lake become very dense, so keep children close and agree a meeting point.
Emergency: 119 for fire and ambulance, 112 for police, and 1330 for the travel hotline.

Frequently Asked Questions
When is cherry blossom season in Seoul?
Between the last days of March and mid-April. The weather agency’s observation tree in Jongno opened on 8 April on average over 1991–2020, but on 29 March in 2026, and recent springs have mostly run early. Watch the flowering forecasts published from late February before you fix your dates.
Where are the best places to see cherry blossom in Seoul?
Yunjung-ro, the cherry avenue behind the National Assembly on Yeouido, and the ring of trees around Seokchon Lake in Songpa are the most famous, and the most crowded. The south bank of the Han between Yeouido and Banpo, the palaces and the hills along the city wall are calmer; go on a weekday morning or evening.
Is yellow dust a problem in April?
Sometimes. April is the heart of the yellow dust season: most days are clear, but a dusty day turns the sky beige and the air gritty. Check the AirKorea forecast each morning, keep a museum day in reserve, and wear a KF94 mask on a high reading if you have asthma or a heart condition.
How much does an April trip to Seoul cost?
April is one of the dearest months for a Seoul room, especially on the peak blossom weekends. Allow about ₩85,000–140,000 a day on a budget and ₩220,000–350,000 mid-range; the blossom itself is free, and a riverside picnic costs less than a restaurant lunch.
What’s the weather like in Seoul in April?
Seoul in April typically sees temperatures of 8–18°C with around 7 days of rain across the period. Pack lightweight layers that suit both cooler mornings and warmer afternoons.
