Recent forecasts from regional models and the Korea Meteorological Administration indicate stable high-pressure conditions over the Korean Peninsula, with northeasterly flow and partly cloudy skies limiting radiative cooling overnight on September 23. These patterns support a daily minimum in the 16–17°C range, consistent with late-September climatology for Busan where average lows trend near 18–20°C but can dip lower under clear, calm conditions. Trader positioning reflects this consensus, with implied probabilities favoring 17°C and 16°C as the most likely outcomes amid limited model spread and no incoming frontal systems or precipitation expected to alter temperatures before midnight. Final official observations from local stations will determine 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.
