Weather model ensembles for Busan reveal modest uncertainty in nocturnal radiative cooling and boundary-layer mixing ahead of August 28, keeping market-implied odds clustered around 24–26 °C for the daily minimum. Persistent high pressure supports mostly clear skies that favor greater heat loss overnight, while variable sea-surface temperatures in the Korea Strait and light southerly flow limit how far inland cooling extends. Ensemble spreads from the Global Forecast System and European Centre for Medium-Range Weather Forecasts show minimum-temperature solutions differing by 2–3 °C depending on exact cloud timing and wind direction. Historical August lows in Busan average near 23–25 °C, so the current distribution reflects typical late-summer variability rather than an extreme signal. Updated model runs and local observations over the next 48 hours will narrow the range 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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
