Official observations from the Korea Meteorological Administration (KMA) confirm Seoul's highest temperature on March 25 reached exactly 13°C at primary monitoring stations like Jongno, solidifying trader consensus at 100% implied probability for this outcome amid typical late-March conditions. Cool northerly airflow and partly cloudy skies capped diurnal maxima, consistent with historical averages of 12-14°C for the period and aligning with pre-event forecast model ensembles from KMA and global centers. This observed data, derived from automated surface stations with rigorous quality controls, leaves negligible room for other outcomes. Realistic challenges—such as rare post hoc data corrections—would require evidence of measurement anomalies, which official protocols deem highly unlikely.

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.
