This market will resolve based on the highest 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 highest temperature recorded at the Incheon Intl Airport Station in degrees Celsius on 22 Aug '26. The resolution source for this market will be information from Wunderground, specifically the highest 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.
Latest forecast models from agencies including the Korea Meteorological Administration show persistent cloud cover, showers, and easterly flow suppressing peak heating for Incheon on August 22, anchoring market-implied odds near 28–29 °C. These conditions reduce incoming solar radiation and promote evaporative cooling, differentiating the closely bunched leading outcomes where even modest changes in cloud timing or precipitation intensity could shift the daily maximum by 1–2 °C. Trader consensus reflects this narrow uncertainty range, informed by recent model runs and current observations of high humidity near 90 % with light winds. Historical August baselines for the region average highs around 29–30 °C, making the anticipated suppression the key driver of positioning ahead of final station readings.
