**Official observations from the Korea Meteorological Administration (KMA) show Busan temperatures peaking near or at 29°C during the afternoon of September 16, 2026, driving the market’s near-certain consensus on that exact outcome.** Real-time station data recorded values reaching 29.2°C around mid-afternoon under clear to partly cloudy skies with northeasterly winds, consistent with model guidance for a mild late-summer day featuring highs in the upper 20s°C. This aligns with typical September climatology for the region, where afternoon maxima often fall in the mid-to-upper 20s before seasonal cooling sets in. The 100% market-implied probability reflects traders’ confidence in KMA’s verified maximum, which serves as the likely resolution source. Only an unexpected post-observation adjustment (such as final quality-controlled data rounding to 28°C or 30°C) or a different official reporting threshold could realistically alter the outcome at this late stage.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Gimhae Intl Airport Station in degrees Celsius on 16 Sep '26.
The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=rkpk
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.**Official observations from the Korea Meteorological Administration (KMA) show Busan temperatures peaking near or at 29°C during the afternoon of September 16, 2026, driving the market’s near-certain consensus on that exact outcome.**
