Official forecasts from the Korea Meteorological Administration indicate Seoul will reach a daytime maximum of 26°C today under persistent cloud cover and scattered showers that limit surface heating and solar radiation. This aligns with late-May climatology, where typical highs hover near 22–25°C amid variable springtime humidity and weak pressure gradients that suppress strong warming. The market’s near-certain 26°C outcome reflects real-time trader consensus on these stable conditions, with minimal upside risk from model runs showing only modest diurnal temperature ranges. A sudden clearing of skies or stronger southerly flow could push readings to 27°C or above, though current observations and short-range guidance make that unlikely before resolution.

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 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.
