If you think Seoul is already hot, brace yourself. Weather experts are warning that temperatures in parts of South Korea could approach 40°C (104°F) as an intense heat wave continues. While Seoul rarely reaches that level, a combination of strong sunshine, hot air moving north, and warm overnight temperatures could push the city close to a historic record. Authorities are urging people to stay hydrated, avoid outdoor activities during the hottest part of the day, and check on elderly neighbors and family members.
South Korea’s Han River (한강, Hangang) is much more than a river—it is one of Seoul’s most recognizable landmarks. But in March 2026, it unexpectedly became the center of an online controversy involving a popular finance app and Korean internet culture.
Korean Internet meme 
What happened?
Korean fintech company Toss introduced a small feature that displayed the current water temperature of the Han River. The feature was originally intended for people enjoying water sports, fishing, and other outdoor activities. However, many users immediately associated it with a well-known piece of Korean stock market slang.
Among Korean investors, asking “What’s the Han River water temperature today?” (한강 물 온도 몇 도야?) is a dark joke. It refers to someone who lost so much money investing that they are joking about jumping into the Han River. Because the phrase is associated with financial losses and suicide, many people felt it was inappropriate for an investment app to display Han River water temperatures.
After criticism spread across social media, Toss quickly removed the feature and stated that it had not intended to reference the meme. The company promised to review its approval process for future mini-apps.
Understanding the Image
The image above is a humorous Korean meme titled:
주식 별 한강다리 집합장소
“Han River Bridge Meeting Places by Stock”
The joke imagines that investors who lose money in different semiconductor stocks would “gather” at different Han River bridges. It is an example of the same dark humor that caused the Toss controversy.
The companies are almost entirely memory-chip and semiconductor businesses, reflecting how popular semiconductor investing is among Korean retail investors.
The small text at the bottom (of the first image above) humorously says:
“Please leave in an orderly manner like citizens of an advanced culture. Investment decisions are your own responsibility.”
In other words, it’s a disclaimer reminding readers that investing carries risk.
Why this matters
For foreigners, this may seem like a harmless joke. In Korea, however, suicide is a serious public health issue, and the expression “checking the Han River temperature” has become widely recognized as a reference to despair after financial losses. That social context explains why many people believed a financial services company should avoid using the phrase—even unintentionally.

한강 Hangang, Han River

투자 tuja, investment
반도체 bandoche, semiconductor
물 온도 mul ondo, water temperature
다리 dari, bridge
The joke has become relevant again because of South Korea’s dramatic stock market correction in 2026. In just 40 days, the Korean stock market lost an estimated ₩2.5 quadrillion (about US$2 trillion) in market value, while the KOSPI index fell roughly 44% from its late-June peak. The decline was fueled by a rapid unwind of AI-related investments, especially in semiconductor companies such as Samsung Electronics and SK hynix, after investors realized expectations had become too optimistic.
During the selloff, the KOSPI suffered back-to-back daily drops of 10.8% and 6%, one of the sharpest corrections in its history. Despite the crash, the market remained more than 40% higher for the year because of its extraordinary rally earlier in 2026, leading some analysts to believe the worst of the panic selling may be over while others warn that volatility could continue.
Step into an elevator in Korea and you’ll notice something immediately—silence. No small talk, no casual greetings, just people standing quietly, often looking at their phones or straight ahead. To many foreigners, this can feel cold or awkward. But in Korea, it’s actually a form of respect.
On arrival at Incheon International Airport, I picked up a T-money Travel Card+ at a convenience store on the first-floor arrivals level, and it quickly became one of the most useful tools for navigating Korea. Unlike a standard transit card, this upgraded version combines three functions in one: transportation, payments, and foreign-friendly money services.
The card works like a typical T-money card for subways, buses, and even taxis across Seoul. But what makes it stand out is its integration with WOWPASS functionality, allowing foreign users to load funds, convert currency, and make purchases at restaurants, shops, and convenience stores without needing a Korean bank account.

Strawberry Nights & Street Bites: A Spring Walk Through Myeong-dong
Spring transforms Seoul’s Myeong-dong into a lively night market filled with bright lights, street food, and fresh strawberries. Vendors line the streets from late afternoon until around 11 PM, selling strawberry tanghulu, cream-filled waffles, and skewered meats. Dessert cafés and cat cafés stay open late, offering a break from the crowds. Seasonal strawberry treats are especially popular from March to April.
And with six Olive Young K-beauty stores, there’s plenty of health and beauty products to shop for too. (Pro Tip- use your home-country Costco membership to get K-Beauty products even cheaper than Olive Young.)

South Korea’s nightlife is evolving into a broader “all-night lifestyle” driven by changing work patterns and consumer behavior. In Seoul, late-night cafés, study lounges, and 24-hour gyms are expanding beyond traditional nightlife hubs like Hongdae and Gangnam into residential districts.
In South Korea, public libraries are far more than places to borrow books. They function as study hubs, cooling centers in summer, and quiet refuges from crowded city life. Many libraries offer spotless facilities, free Wi-Fi, personal desk lamps, and designated zones for students, adults, and seniors. It’s common to see people spending entire afternoons reading, preparing for exams, or simply resting.
