This market will resolve to the temperature range that contains the highest temperature recorded at the Incheon Intl Airport Station in degrees Celsius on 23 May '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Incheon Intl Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/kr/incheon/RKSI. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C. This market can not resolve to "Yes" until all data for this date has been finalized. The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Current observations from the Korea Meteorological Administration at Seoul’s central station show a daytime peak of 22°C under partly cloudy skies with light easterly winds and no precipitation, aligning with model consensus that suppressed further warming below typical late-May climatology of 23–24°C. This data anchors the near-certain market-implied probability for a 22°C high, reflecting real-time hourly readings that remained at or below this threshold through afternoon hours. Minor upward revisions remain possible if final daily summaries incorporate slightly higher peripheral station values or if post-sunset adjustments alter the official maximum, though KMA’s standardized methodology makes such shifts unlikely before resolution.
