This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Incheon Intl Airport Station in degrees Celsius on 6 Sep '26. The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=rksi If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source. In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket. To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C. This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first. 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.
Trader consensus strongly favors a 20°C daily minimum for Seoul/Incheon on September 6, 2026, at 98.5% implied probability. Official forecasts from the Korea Meteorological Administration and Incheon International Airport, along with multiple international models, project a nighttime low of 19–20°C under clear to mostly clear skies and steady northeasterly winds of 7–10 kt. These conditions support moderate radiative cooling without significant additional drop, consistent with early-September climatology for the region where average September lows hover near 18–20°C. Current model consensus shows minimal spread, with no incoming cold air mass, frontal passage, or precipitation expected to enhance cooling. The market reflects this high-confidence outlook from real-time observational trends and numerical weather prediction runs. A realistic challenge would require an unforeseen increase in cloud cover or a sharper wind shift that limits mixing, though such changes appear unlikely within the final 24-hour forecast window.
