Current forecasts from global and regional models, including those aligned with Korea Meteorological Administration guidance, point to a minimum temperature near 21°C for Busan on September 14 under mostly clear skies and light easterly winds. This setup favors moderate nocturnal radiative cooling, with dew points around 16–18°C limiting further drops unless winds calm significantly. Trader consensus remains closely balanced because small shifts in overnight cloud cover, boundary-layer humidity, or sea-breeze timing can easily move the low between 19–23°C, while historical September variability and model spread keep lower-probability tails (sub-17°C or above-25°C) priced near even. Updated runs and surface observations over the next 48 hours will refine the exact cooling rate ahead of market resolution.

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.
