Trader consensus on the highest temperature in Busan on September 21 centers on 28°C or 29°C because ensemble forecasts from the Korea Meteorological Administration and global models such as ECMWF and GFS converge on maximums near these values under a weakening high-pressure ridge. Subtle differences in predicted wind direction, afternoon sea-breeze timing, and boundary-layer moisture create the tight split, with 28°C slightly favored. Late-September climatology for the region shows typical highs of 26–29°C, so current guidance aligns with historical norms rather than extremes. Updated model runs and morning observations will refine the outcome before resolution.

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 21 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.Trader consensus on the highest temperature in Busan on September 21 centers on 28°C or 29°C because ensemble forecasts from the Korea Meteorological Administration and global models such as ECMWF and GFS converge on maximums near these values under a weakening high-pressure ridge.
