Current forecast models for Busan on September 13 point to an overnight low near 20°C under clear skies and light winds, consistent with high-pressure stability and typical early-fall radiative cooling along the coast. Sea-surface temperatures moderate the drop, while low humidity and calm conditions allow efficient heat loss overnight, though minor model spreads in timing or cloud cover could shift the exact minimum by 1–2°C. Trader consensus clusters tightly around 19–21°C outcomes, with the 25°C+ share reflecting residual uncertainty over any unexpected warming or measurement variance rather than baseline guidance. No significant weather systems are expected to alter the pattern before 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.
