Recent forecasts from the Korea Meteorological Administration and global models highlight persistent northeast winds and extensive cloud cover over Busan on September 4 as the dominant factors capping daytime heating. These conditions, typical of early September post-monsoon patterns, are expected to limit the daily maximum to 27–28 °C, consistent with climatological normals of approximately 27 °C. Ensemble guidance shows modest spread, with some runs permitting brief clearing that could push peaks to 29 °C, supporting the market’s leading 29 °C (47.5 %) and 28 °C (28.5 %) outcomes. Strong winds will enhance mixing and suppress localized warming, while low precipitation risk reduces evaporative cooling effects. Updated model runs and official KMA briefings tomorrow morning represent the key data points that could refine these market-implied probabilities.

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.
