The title asks for the highest temperature in Seoul, but the resolution rules strictly specify data from the Incheon Intl Airport Station. Incheon is a coastal city, and its microclimate often differs from inland Seoul. Traders who only look at the title and check Seoul's forecast may easily fall into this trap.

2026-04-22 to 2026-04-23, the price of '21°C or higher' surged from 35.5c to 77.5c, while '19°C' and '18°C' plunged from 21.5c to 8c and from 16.5c to 3.5c respectively. This was driven by updated Wunderground forecast models projecting a definitive high of 73°F (23°C), causing capital to rapidly consolidate into the highest temperature bracket.

Predicting the daily high temperature for a specific city is a standard derivative on prediction markets, yet betting on the exact temperature of a single day remains a somewhat niche and novelty topic for the general public.

The rules specify the SAEZ airport station rather than downtown Buenos Aires, which often experience noticeable temperature differences. Additionally, resolution relies strictly on Wunderground's rounded integer data; any temporary missing data or discrepancies with official meteorological sources on this specific platform could introduce unexpected risks.
