Recent forecasts from agencies including the Korea Meteorological Administration indicate Busan’s overnight low on September 16 will likely settle near 21–22 °C, with trader consensus split across 19–21 °C reflecting model uncertainty in the precise minimum. Clear to partly cloudy skies permit enhanced longwave radiative cooling after sunset, while persistent northeasterly winds of 10–15 mph limit boundary-layer decoupling and advect slightly warmer marine air. Dew points around 15–17 °C and moderate humidity further moderate the drop by reducing the temperature-dewpoint spread. These factors, combined with typical September climatology showing average lows near 21 °C, keep the 19–21 °C outcomes tightly contested as final observations are recorded.

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.
