Recent forecasts from sources including the Korea Meteorological Administration and international models indicate Busan’s overnight minimum on September 21 will likely reach 18–19 °C under clearing high pressure and light northerly winds following scattered rain on the 18th. Clear skies promote strong radiative cooling at night, while seasonal sea-surface temperatures near 24–25 °C limit further drops; however, slight variations in wind speed or residual moisture could shift the exact low by 1–2 °C. Trader consensus remains closely divided between sub-14 °C and 23 °C+ outcomes because small differences in boundary-layer mixing or cloud cover can meaningfully alter the daily minimum relative to climatological September averages of 19–21 °C. Updated model runs and official 48-hour forecasts will provide the next key data points.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Gimhae Intl Airport Station in degrees Celsius on 21 Sep '26.
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.Recent forecasts from sources including the Korea Meteorological Administration and international models indicate Busan’s overnight minimum on September 21 will likely reach 18–19 °C under clearing high pressure and light northerly winds following scattered rain on the 18th.
