Hello, this is Sokcho Eottae. As of 6 p.m. on Tuesday, September 29, Sokcho (속초) is clear at 21°C. Today's high is 23°C and the low is 18°C. The most widely reported Sokcho news today is about a summer concert that ended a month ago. The mobile carrier big data analysis of 'Waterbomb Sokcho 2026', held on August 22, came out today, and the key point comes down to one thing: two hours after the concert ended, 61.4% of out-of-town visitors were still in Sokcho.
It means that when the concert ended, people did not head straight for the expressway. We've laid out, in order, what this number says, how far it can be trusted, and how those of you in Sokcho this evening can make use of the results.
What was Waterbomb Sokcho 2026?
Waterbomb is a summer festival that combines music performances with water play. It has been held in Sokcho for the fourth year in a row this year, and this year it took place on August 22 at the outdoor grounds of 한화리조트 설악 쏘라노 (Hanwha Resort Seorak Sorano). The analysis was carried out by the City of Sokcho together with the Korea University Digital Innovation Research Center (고려대학교 디지털혁신연구센터) using mobile carrier big data. Rather than asking "Did you stay?" as a survey would, it looked at where people actually were and for how long based on mobile phone signals, so the data is closer to actual movement than to impressions.
Who came: more than 8 in 10 were from outside the area
- Visitors to the analyzed area on the day of the event: 23,981
- Share of out-of-town visitors: 85.2% (20,422)
- Share of out-of-town visitors living in the Seoul metropolitan area: 74.6% (Gyeonggi 37.1%, Seoul 31.9%)
- Main age groups: 20s to 40s
Breaking down the numbers, most of the people around the venue were in their 20s to 40s and came from Gyeonggi and Seoul. When the concert ends in the evening, these people have to make a choice: head straight back via Misiryeong-ro (미시령로) or the Seoul–Yangyang Expressway (서울양양고속도로), or spend the night in Sokcho and leave the next day. Since driving more than six hours round trip for a single concert is a burden, a large share stayed in Sokcho, and this analysis showed that in numbers.
Two hours after the concert, where were the 61.4%?
According to the analysis, the out-of-town visitors who remained two hours after the concert ended mainly stayed in or moved around Nohak-dong (노학동), Yeongnang-dong (영랑동), and Geumho-dong (금호동). They appear to have taken care of lodging and meals in these areas.
- Nohak-dong: This is the neighborhood where the venue, Sorano, is located. With lodging and restaurants within walking distance, it was the first place people flocked to.
- Yeongnang-dong and Geumho-dong: These lie in the direction heading down from the venue toward downtown and the seaside. They can be seen as the places where people who booked lodging downtown had a late dinner or continued drinking.
Average length of stay also increased across all types of visitors. Comparing the week of the event with the comparison period:
- Out-of-town visitors: 1.3 hours → 1.6 hours
- Local residents: 0.9 hours → 1.3 hours
- Foreign visitors: 1.5 hours → 1.9 hours
The part worth noting is local residents. Their increase of 0.4 hours was larger than that of out-of-town visitors (0.3 hours). This means Sokcho residents also stayed out later than usual on concert day. It can be read as the street atmosphere on event day increasing residents' evening outings as well.
Late-night sales up 3.9%: how should we read this number?
Sales in the analyzed commercial districts on the day of the event were about 6.49 billion KRW, and sales between 11 p.m. and 2 a.m. rose 3.9% compared with the comparison periods before and after the event.
However, this number needs to be looked at in parts.
- The 6.49 billion KRW is not sales generated by Waterbomb. It is the total of all sales that occurred in the analyzed commercial districts over that entire day. It includes ordinary sales as well.
- 3.9% is not large, but it is meaningful. After 11 p.m. is a time slot when sales normally drop sharply. An increase in sales at this time means that people who dispersed after the concert actually went looking for late meals, convenience stores, and bars.
- The effect probably varied from business to business. Businesses open late in Nohak-dong, Yeongnang-dong, and Geumho-dong would have felt it strongly, but businesses that close at 9 p.m. may not have noticed any difference.
In the end, what this analysis says is closer to "it can keep people in Sokcho until late at night" than "the concert made a lot of money." Sokcho has long had the limitation of being a place where people see Seoraksan (설악산) and the sea on a day trip and head back. This is effectively the first time evidence has come out in numbers that a large concert can shift that pattern toward staying the night.
What the City of Sokcho handled on the day
On the day of the event, the City of Sokcho checked on heat wave response, easing traffic congestion, and stamping out price gouging, and provided information on restaurants open late at night through its official channels. Letting out-of-town visitors who didn't know where to eat after the concert know about restaurants in advance can be seen as connected to the late-night sales as well.
Sokcho Mayor Lee Byung-sun (이병선) assessed that the results showed the potential for large concerts to lead to stay-based tourism. He said the city will strengthen links that bundle concerts, transportation, lodging, and tourism to meet tourism demand from people in their 20s to 40s.
Sokcho this evening: here's how to use these results
Applying the big data results directly to this evening yields a few useful tips. Let's start with the current situation in Sokcho.
- Tourist site congestion: Daepo Port (대포항) Observatory very crowded; Oeongchi Port (외옹치항), Forest Museum (숲박물관), Sokcho Expo Tower (속초 엑스포타워), 한화리조트 설악 워터피아 (Hanwha Resort Seorak Waterpia), and the Sokcho Joyang-dong Historic Site (속초 조양동 유적) crowded
- Inbound traffic (estimated): Misiryeong-ro (toward Seoul) slow, Donghae-daero (동해대로) (coast and downtown) slow, Seoraksan-ro (설악산로) (toward Seorak) smooth
- Sea: water temperature 23.1°C, wave height 0.9 m
- Chance of rain: 42%
First, shift your dinner plans a little. Seeing that both Daepo Port and Oeongchi Port are busy, evening demand is concentrated on the coast. Donghae-daero is also slow, so if you drive up to the front of the ports, you'll get stuck just trying to park. If you turn toward downtown restaurants in Yeongnang-dong and Geumho-dong, where people dispersed on Waterbomb day, you'll find a bit more room.
Second, if you're heading back to Seoul, it's better not to rush. Right now Misiryeong-ro toward Seoul is slow. Since it's a weekday evening, this is also the time when commuter traffic overlaps. If the road is going to be congested anyway, eating dinner and leaving an hour or two later means less driving fatigue. The 61.4% of out-of-town visitors who stayed on Waterbomb day probably made the same judgment.
Third, just look at the sea. With a water temperature of 23.1°C and a wave height of 0.9 m, the sea is fairly calm, but Sokcho's beaches closed at the end of August and there are no lifeguards. Avoid going in the water after dark, and it's safer to be content with a walk on the beach.
Fourth, bring a small umbrella. It's clear right now, but the chance of rain is 42%. If you plan to walk back to your lodging late at night, it's a good idea to keep an umbrella in your bag.
This week, a series of events will test 'Sokcho as a place to stay'
This week, when the Waterbomb analysis came out, happens to be lined up with events that could keep people around.
- September 30 (Wed): 2026 Sokcho Chrysanthemum Exhibition opens around Cheongchoho Lake (청초호) (through November 8), 120,000 chrysanthemums
- October 2–4: Seorak Cultural Festival (설악문화제), around the Expo Lawn Plaza
- October 3 (Sat): Seorak Cultural Festival parade
- October 5 (Mon): Substitute public holiday
With a three-day holiday running from National Foundation Day through the substitute holiday, there is plenty of reason for people in their 20s to 40s from the Seoul metropolitan area to stay the night, just like Waterbomb. This time you'll probably be able to feel it even without big data analysis results. If you haven't booked lodging yet, we recommend checking within this week.
From residents' point of view
For residents, these results have two faces. For businesses that stay open late, there is now evidence that days with large concerts are an opportunity. Since the City of Sokcho promoted late-night restaurants through its official channels, letting the city know your business hours before an event increases your chances of being included in the list. On the other hand, in neighborhoods around the venue such as Nohak-dong, noise and parking problems may continue late into the night on concert days. As the city has said it will strengthen links bundling concerts, transportation, and lodging, we hope ways to reduce inconvenience for residents will come out of that process as well.
Sokcho Eottae will also keep checking and reporting congestion and inbound traffic on days with large events.
Today we looked at 'Sokcho, where people stayed even after the concert ended' through the Waterbomb Sokcho 2026 big data analysis, along with tips for this evening. Did you find it helpful? We'll be back next time with even more useful information.
