This market will resolve based on the lowest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section. This market will resolve to the temperature range that contains the lowest temperature recorded at the Incheon Intl Airport Station in degrees Celsius on 17 Aug '26. The resolution source for this market will be information from Wunderground, specifically the lowest temperature recorded for all times on this day for the Incheon Intl Airport Station, 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 until the first data point for the following date has been published on the resolution source. 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. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
Official forecasts from the Korea Meteorological Administration (KMA) indicate a minimum temperature of 24°C for Seoul and Incheon on August 17, 2026, under mostly cloudy morning conditions transitioning to afternoon showers. This aligns with typical mid-August patterns in the region, where high humidity, cloud cover, and a forecast high of 31°C limit overnight radiative cooling and keep lows near or slightly above seasonal averages of around 23°C. Multiple short-range model runs and updated KMA guidance show consistent results without significant downward revisions, supporting the market's strong 93% implied probability for exactly 24°C as the lowest temperature recorded. Traders appear to weigh the official observational criteria and limited variability expected in the final hours. A realistic challenge would require clearer skies or unexpected cold advection that drops readings to 23°C or below, though current consensus and proximity to the observation window make such shifts unlikely.
