Recent ensemble forecasts from major models show Busan minimum temperatures on September 5 likely falling in the low-to-mid 20s Celsius, with official guidance centering near 23–24 °C amid persistent northeasterly flow and variable cloud cover that limits overnight radiative cooling. The closely matched market-implied odds reflect genuine forecast spread, as small shifts in wind strength, marine layer depth, or timing of any passing disturbances can alter the daily minimum by several degrees. Historical September climatology for the region places typical lows near 22–24 °C, providing context for the current distribution. Traders will watch the next GFS and ECMWF runs, plus any updated guidance from the Korea Meteorological Administration, for signals that could resolve the narrow range between cooler and warmer outcomes.

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=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.
