The overwhelming 100% market-implied probability for a 17°C low in Seoul on May 31 stems from tight consensus across Korea Meteorological Administration and international model runs, which project this exact overnight minimum under clear to partly cloudy skies, light variable winds, and typical late-May radiative cooling with humidity near 60%. These conditions favor efficient surface heat loss without significant advection or cloud cover to moderate temperatures. Historical climatology for the period shows average lows around 14–16°C, but current atmospheric setup aligns closely with 17°C. Minor shifts in boundary-layer mixing, localized urban heat-island effects at the official station, or last-hour forecast adjustments could realistically produce a 16°C or 18°C reading and alter resolution.

This market will resolve to the temperature range that contains the lowest temperature recorded at the Incheon Intl Airport Station in degrees Celsius on 31 May '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.The overwhelming 100% market-implied probability for a 17°C low in Seoul on May 31 stems from tight consensus across Korea Meteorological Administration and international model runs, which project this exact overnight minimum under clear to partly cloudy skies, light variable winds, and typical late-May radiative cooling with humidity near 60%.
