Current forecasts from multiple meteorological models project Busan’s overnight low on September 7 near 21–23°C, shaped by persistent northeasterly flow off the Sea of Japan, moderate humidity, and limited overnight cloud cover that permits moderate radiative cooling. Coastal marine influence and typical early-September climatology (historical lows averaging 20–22°C) anchor expectations away from extremes, yet small variations in wind speed or boundary-layer moisture can shift the exact minimum by 1–2°C. Trader consensus, with 28°C+ and 18°C-or-below outcomes nearly tied, reflects this narrow uncertainty band and the resolution criteria tied to official Korea Meteorological Administration observations rather than any single model run.

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.
