Current forecasts from GFS and other models indicate Busan will experience stable late-September conditions on the 24th, with partly cloudy skies, light winds shifting from northeast to southeast, and overnight radiative cooling under modest humidity supporting a minimum near 19–21°C. This aligns with climatological averages around 19°C for the date and recent observations showing no strong cold advection or typhoon influence. Trader balance between sub-13°C and 23°C+ outcomes reflects model spread in exact cooling rates and potential for localized sea-breeze moderation or brief cloud increases that could shift the recorded low by a few degrees. Upcoming model runs and official Korea Meteorological Administration updates will likely tighten consensus ahead of 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.
