Diverging short-term forecast models are driving the near-even split between the 13°C-or-below and 23°C-or-higher outcomes for Busan’s minimum temperature on September 24. Recent ensemble runs show a potential cold front or northerly flow advecting cooler air from the continent, which could enhance nocturnal radiative cooling under clearer skies, while other solutions favor persistent southerly maritime air from the Korea Strait that would keep overnight lows elevated. Sea-surface temperatures near 24–26°C provide a strong moderating influence, limiting how far readings can fall even with clear conditions. Historical late-September climatology for Busan centers around 18–20°C minima, underscoring the current forecast spread. Traders are watching the next KMA and ECMWF model cycles for shifts in the 500-hPa pattern that would resolve the bimodal risk.

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.
