Latest ensemble forecasts from the Korea Meteorological Administration and global models indicate a maximum temperature near 28–29°C in Busan on September 14 under stable high pressure, clear to partly cloudy skies, and light easterly or southerly winds that limit vertical mixing and moisture influx. These conditions align with late-summer climatology for the region, where diurnal warming peaks in the afternoon before moderating overnight. Market-implied odds favoring 31°C reflect trader assessment of model spread, potential urban heat island effects, and slight upward bias in some high-resolution runs, while lower-probability outcomes capture risks of greater cloud cover or wind shifts that could cap the daily high. Official KMA verification data will resolve the market once released.

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.
