Current forecast models from sources like WeatherBug and PredictWind indicate a minimum temperature near 21–22°C for Busan on September 17 under persistent northeasterly winds, partly to mostly cloudy skies, and stable high pressure. These conditions limit overnight radiative cooling over the coastal location while moderating temperatures through marine influence. Trader consensus clusters around 19–20°C as the implied lowest, reflecting minor model spreads in cloud cover and wind strength that could enhance cooling. Lower outcomes below 18°C carry weight due to historical variability in early autumn patterns, though recent observations show no major frontal systems or typhoon activity to drive sharper drops. Updated model runs and local station data in the next 48 hours will refine these probabilities.

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.
